项目摘要

In the cement industry, the contribution to the sustainable society is requested, and it is demanded to increase the usage of waste at cement manufacture. Because the content of Al_2O_3 for wastes is higher than the composition of cement, he contents of aluminates phase of cement should be increased for increasing the utilization amounts of waste disposal in cement production. It is possible that the fluidity of cement paste is increased and the hydration shrinkage of cement paste is decreased by the increasing of aluminate phase. Therefore, it is necessary to arrange the material design of blended cement when the amount of cement of aluminate phase in cement increases. In this study, the following items are discussed.1)Arrangement of matter that should be considered on material design of blended cement based on hydration analysis2)Characterization of slowly cooled blast furnace slag3)Merits and demerits of aluminate phase4)Controlling methods for fluidity of cement with high contents … More of C_3A by using of additivesIt proposed the material design method of blended cement and ordinary cement in the future based on the above-mentioned. The influence of various admixtures on the reaction of the cement compound and the reaction of them were clarified. The factors that had to be considered on the material design of the chemical composition, fineness, and the glassiness ratio etc. of the mineral admixtures were summarized. In addition, the reduction effect of the slowly cooled blast furnace slag was discussed.. The aluminate phase in cement is effective for the immobilization of harmful ions. However, the flowability of cement decreases wit increasing of the contents of aluminate phase. When the aluminate phase was adjusted to about 8% or less, it was clarified that the control of the flowability of cement was easy. In addition, it was clarified that it was effective to decrease the amount of the aluminate phase by using the mineral admixtures by about 20-30 mass% as a controlling method of the flowability of cement that increased the usage of waste, and increased the aluminate phase.

在水泥工业中,要求对可持续社会做出贡献,并要求增加水泥制造中废物的使用。由于废弃物中Al_2O_3的含量高于水泥的组成,为了提高废弃物在水泥生产中的利用量,应增加水泥中铝酸盐相的含量。铝酸盐相含量的增加有可能提高水泥净浆的流动度,降低水泥净浆的水化收缩。因此,当水泥中铝酸盐相水泥的掺量增加时,有必要安排混合水泥的材料设计。本文主要研究了以下几个问题:1)基于水化分析的混合水泥材料设计中应考虑的问题的安排2)缓冷高炉矿渣的表征3)铝酸盐相的优缺点4)高掺量水泥流动度的控制方法 ...更多信息 在此基础上提出了今后混合水泥和普通水泥的材料设计方法。阐明了各种外加剂对水泥胶凝材料反应的影响以及它们之间的反应。总结了矿物掺合料的化学组成、细度、玻璃化率等材料设计时应考虑的因素。此外,还对缓冷高炉渣的还原效果进行了探讨.水泥中的铝酸盐相对有害离子的固定是有效的。但随着铝酸盐相含量的增加,水泥的流动性降低。当铝酸盐相被调节到约8%或更少时,可以清楚地看出,水泥的流动性的控制是容易的。此外,可以明确,通过使用约20-30质量%的矿物掺合料作为水泥流动性的控制方法来减少铝酸盐相的量是有效的,这增加了废物的使用,并且增加了铝酸盐相。少
