Sang-Chul Shin，Jeong-Min Ra，In-Gyu Kang，Jun-Hyeong Park，Jin-Man Kim and Tomoyuki Koyama, A study on the basic properties of cement paste and mortar using carbonated water, Proceedings of the 14th Japan・Korea Joint Symposium on Building Materials & Construction July 2022, 33-38, 2022.07, This study is a basic study for developing carbonation technology that captures and stores carbon dioxide in the cement and concrete industries. This study aimed to confirm the possibility of developing CO2 utilization technology in ready-mixed concrete plant by examining the basic characteristics of cement paste and cement mortar made by using carbonated water in the H2CO3 state, produced by injecting CO2 into the water, as mixing water. The results of this study confirmed that using carbonated water as the mixing water for cement composites delayed hydration while securing an equivalent strength level. It is expected that further developing these results would produce results for the commercialization of CCUS technology in the South Korean cement-concrete field. Furthermore, it will ultimately contribute to carbon neutrality in the cement industry by using carbon dioxide.. |

S.C. SHIN, T. KOYAMA, K. ITO, T. HAYAKAWA and J.M. KIM, A Study on the Quality Improvement of Concrete by the Self-curing Effect of Artificial Lightweight Aggregate in Hot Weather Condition, The 9th International Conference of Asian Concrete Federation (ACF2020/2021), 2021.11, In case of concrete constructed in hot weather environment, more mixing water is needed since slump decreases rapidly and the surface dries quickly. As one method for supplying water, the porosity of artificial light weight aggregate provides source of water for internal curing of concrete which enhances concrete strength and durability and it is called a self-curing effect. This study was investigated for the qualities of hot weather concrete by self-curing effect of the artificial light weight aggregate. The properties of concrete, in which 25 and 50% of fine aggregates are replaced by artificial light weight fine aggregates, were examined. As the results of the experiment, concrete with artificial light weight aggregate is effective on the finishing workability, compressive strength and durability due to the self-curing effect in hot weather condition. Therefore, this paper showed that using artificial light weight aggregate is considered to be effective in quality improvement of hot weather concrete.. |

湯浅 昇，野中 英，小山智幸, 暑中期におけるレディーミクストコンクリートの材料温度に関する調査検討, 日本建築学会技術報告集, 27, 66, 614-617, 2021.06, This report examines the effect of temperature up to 3 days after casting on the standard curing strength. When cured at low temperature up to 3 days of age, the standard curing strength increases, and when curing at high temperature up to 3 days, the standard curing strength is low. In the high strength concrete, the structure strength correction value will be overestimated if the curing temperature is normal temperature in summer. In hot weather concreting for general strength range, if the curing temperature is normal temperature, the structure strength correction value will be overestimated by about 3N / mm2.. |

The use of silica fume with a replacement ratio of 24%, which contained 50% coarse silica flour, attained both high compressive strength and high fluidity. The newly developed chemical admixture showed excellent dispersibility down to 10% water-to-binder ratio, which improved concrete workability, mitigated the delayed setting times, and resulted in 30% less shrinkage and 7% strength gain. For the design strength of 300N/mm2, satisfactory strength and workability can be reached with the specific aggregates and curing scheme reported in our previous study.. |

The fine aggregate type was found to significantly influence compressive strength development, and the use of quartz fine aggregates yielded the highest strength. The strength of the mortar specimens made of blended cement containing silica fume reached 350〜400N/mm2 with a two-stage heat curing scheme. For concrete, the type and maximum size of coarse aggregates greatly affect the strength; the use of rhyolites up to 10mm resulted in approximately 300N/mm2. The use of homogenous high-strength aggregates does not necessarily yield high concrete strength, likely due to the difference in Poisson’s ratio.. |

This study examined the effectiveness of self-curing effects of artificial lightweight aggregates on concrete that has been constructed in hot weather environments. The test specimens were constructed as concrete slabs and columns simulating that used for construction in a temperature controlled environment of more than 35℃. The types of concrete used were: normal concrete, lightweight concrete type I, and a modified normal concrete containing lightweight fine aggregate. During curing the concrete’s physical properties and the hydration reactivity of its internal cement was evaluated. As a result, compared to normal concrete, the concrete using the artificial lightweight aggregate had an improved compressive strength and air permeability in the hot weather environment. With respect to the lightweight concrete type 1, crack resistance was also observed. The analysis results of the cement hydration degree in hardened concrete also indicated that the hydration reaction in concrete using the artificial lightweight aggregate had progressed properly, confirming the effectiveness of the self-curing effect of lightweight aggregates.. |

geopolymer activated in NaOH and NaOH+ Na2SiO3 was studied regarding setting time, compressive
strength, porosity, microstructure, and formation of crystalline phases. When comparing the effects of
alkali type on the FA and GGBS geopolymer composites, results revealed that NaOH has a lesser effect in developing strength and denser microstructure than does NaOH + Na2SiO3, since the addition of Na2SiO3 provides the silica source to develop more compact structure. Incorporation of Na2SiO3 reduced the crystallinity and the paste was more amorphous compared to NaOH activated pastes. The class-C FA and GGBS blends resulted in prolonged setting time, reduced strength, and loose
matrix with the increase in fly ash content. The un-reactivity of calcium in blends was observed with
increasing fly ash content, leading to strength loss. It is evident from XRD patterns that calcium in
fly ash did not contribute in forming C-S-H bond, but formation of crystalline calcite was observed.
Furthermore, XRD analyses revealed that the reduction in fly ash leads to the reduction in crystallinity, and SEM micrographs showed the unreactive fly ash particles, which hinder the formation of a denser matrix.. |

Although the degree of risk of frost damage is rank 1 in the vicinity of Aso and Unzen in Kyushu, frost damage occurs in other inland areas and mountainous areas. In cold areas, frost damage is likely to occur on the south side because the maximum temperature is often below freezing, and once concrete is frozen it must require the action of solar radiation to melt. However, in Kyushu, the lowest temperature rarely is below freezing, and concrete can be melted without the action of solar radiation. Therefore, in order to know the characteristics of frost damage in Kyushu, we made visual investigation of concrete structures. As a result, we found that the frost damage in Kyushu has characteristics different from those in cold areas such as deterioration seen in all directions..  |

Sangchul SHIN, Tomoyuki Koyama, Korekiyo ITO, A STUDY ON THE MOCK-UP TEST FOR QUALITY CONTROL OF FLOOR SLAB CONCRETE ACCORDING TO CURING METHOD UNDER HOT WEATHER, The 7th International Conference of Asian Concrete Federation, 2016.11, This study was conducted to investigate the initial water movement and the hydration property of poured concrete under a hot weather environment and examined impacts from the curing method (water curing, sheet curing and membrane curing), start time and period of curing to the strength and durability of hardened concrete. The floor slab specimens produced in the size of 800 × 800 × 200 mm to consider real construction site. The results of this mock-up test indicate that the bleeding is finished after 3.5 hours, the concrete surface becomes dried state rapidly, and the hydration reaction was very fast in the hot weather condition. Curing is effective if it is started from the point of bleeding ending and start of surface drying. For curing method, the water curing is most effective. If the water curing is complicated, the quality control though the sheet curing or the membrane curing is available.. |

Especially in case of the vertical members such as walls and columns, it should be assured the early intervals of concrete placing time for consolidation with the previous concrete. Therefore, this study was conducted to investigate the effect of concrete placing time and interval of vertical members affecting the development of the cold joint under hot weather environment. As experimental factors of this mockup test, concrete placing time was set 0.5 and 1.5 hours, and the intervals of concrete placing time was set at 1, 2 and 3 hours. Experiment results indicate that the bleeding is finished after 2 hours, the concrete surface becomes dried state rapidly, and the hydration reaction was very fast in the hot weather condition. When approaching from the experimental factors, intervals of placing time was a dominant influence on the air permeability coefficient compared with concrete placing time. If proposed the air permeability coefficient in 10(×10-16m2) or less for quality control in respect of cold joint under hot weather environment, later concrete should be poured within 2 hours. Additionally, in the scope of this experiment, 1.0N/mm2 of Proctor penetration resistance and 50～60mm of N-type penetration depth can suggest a limits of placing time of later concrete.. |

Therefore, this study was conducted to investigate the effect of curing by reviewing the various characteristics according to curing method in order to control the quality of floor slab concrete under hot weather environment. Concrete curing was performed through three kinds of method: water spray curing, sheet curing and non-curing. Especially in the case of water spray curing, the start time of watering was set different. As the result of experiments, Even if floor slab concrete is manufactured in hot weather, the temperature of concrete did not rise significantly in comparison with column concrete specimen. In addition, Experiment results indicate that water spray curing is effective on the compressive strength, neutralization and air permeability. On the other hand, the characteristic difference of floor slab concrete according to curing method was not significant under standard weather environment. In addition, it was confirmed that the water curing within a few hours of placing is effective in order to satisfy both the strength and durability of concrete under hot weather environment.. |

Medium-low level radioactive waste, which is composed mainly of the liquid ion exchange resin, has been consolidated with cementitious material in the plastic or iron container. Since cementitious material is brittle, it would generate cracks by impact load during transportation, signifying leakage of radioactive ray. In order to design the safety transporting equipment, there is a need to check the compressive strength of the current waste. However, because it is impossible to measure strength by direct method due to leakage of radioactive ray, we will estimate the strength indirectly by the dynamic modulus of elasticity. Therefore, it must be identified the relationship between of strength and dynamic modulus of elasticity. According to the waste acceptance criteria, the compressive strength of cement based solid is defined as more than 3.44 MPa (500 psi). Compressive strength of the present solid is likely to be significantly higher than this baseline because of continuous hydration of cement during long period. On this background, we have tried to produce the specimens of the 28 day's compressive strength of 3 to 30 MPa having the same material composition as the solid product for the medium-low level radioactive waste, and analyze the relationship between the strength and the dynamic modulus of elasticity. By controling the addition rates of AE agent, we made the mixture containing the ion exchange resin and showing the target compressive strength(3 ∼ 30 MPa). The dynamic modulus of elasticity of this mixtures is 4.1∼10.2 GPa, about 20 GPa lower in the equivalent compressive strength level than that of ordinary concrete, and increasing the discrepancy according to increase strength. The compressive strength and the dynamic modulus of elasticity show the liner relationship.. |

In this study, the methods were discussed using the data opened to the public by Japan Meteorological Agency. The method described in JASS5 tends to estimate the period shorter due to the effect of recent global warming. The presented method using the mean value of ambient temperature at the nearest ten years could estimate better than the traditional one using the normal values. Additionally, it was shown that the length and severity of hot weather ambience were correlated well. . |

－弱酸性の硫酸環境における長期曝露実験－, 都市・建築学研究，九州大学大学院人間環境学研究院紀要, 21, 41-47, 2012.01, Long term exposure tests on sulfuric acid resistance of concrete containing a large quantity of fly ash with constant cement content were carried out under weak acid environment, i.e., in the atmosphere and soil which has a pH value between 4 and 5. In six years’ exposure tests, the following results were obtained.
a) Specimens embedded in the acid soil expanded slightly, but cracking was not observed on the surfaces of the specimens. b) In specimens with no fly ash content (Portland cement only) or with low fly ash content, those surface parts were dissolved severely by sulfuric acid. Nevertheless, dynamic modulus of elasticity of these specimens was unimpaired. c) It was confirmed that with an increase in the fly ash content, the resistance of concrete to sulfuric acid improved, in other words, dissolution and discoloration of the surface parts hardly occurred.. |

―実大柱および壁試験体による検討―, 都市・建築学研究，九州大学大学院人間環境学研究院紀要, 20, 129-138, 2011.07, This study was carried out with the aim of investigating the influence that the high temperature of ready mixed concrete as delivered and the time for formwork to remain in place exerted on the correction value of concrete strength and the carbonation ratio of the concrete on hot weather concreting. The specimens in the experiments were placed at 35℃ and 38℃ of the temperature of concrete as delivered. The times for formwork to remain in place of the specimen were from 1 day to 28 days. This paper describes that the appropriate correction value of concrete strength is 6N/mm2 on hot weather concreting and the time for formwork to remain in place shall be 5 days or longer from the view of the durability if the temperature of concrete as delivered exceeds 35℃.. |
