摘要： PROBLEM TO BE SOLVED: To provide a preparation method for low shrinkage AE concrete which has such multi-functions simultaneously that the entrained air of concrete after kneading is not defoamed, the air content is held stably with time and the dry shrinkage rate of the obtained hardening body is small, the occurrence of cracks is controlled, further the freezing and thawing resistance of the hardening body is excellent, and still further the void occurrence on the surface of concrete of the obtained hardened body after curing and the surface appearance is beautiful, and to provide the low shrinkage AE concrete obtained by the preparation method.SOLUTION: The preparation method for the low shrinkage AE concrete comprises a step of adding 0.1-8.0 pts.mass of a low shrinkage reduction fluidizing agent per 100 pts.mass of cement in the base concrete to stiff-consistency base concrete that has been kneaded and mixed in advance.
摘要翻译：要解决的问题：为了提供具有这样多功能的低收缩AE混凝土的制备方法，即混合后混凝土的夹带空气不脱泡，空气含量随时间稳定地保持，干收缩率所得到的硬化体小，控制裂纹的发生，硬化体的抗冻融性进一步优异，而且，硬化后的硬化体的混凝土表面的空隙发生变化，表面外观是美丽的，并提供通过制备方法获得的低收缩AE混凝土。
解决方案：低收缩率AE混凝土的制备方法包括在基础混凝土中向刚性基础混凝土中加入0.1-8.0重量份的低收缩减少流化剂/ 100磅水泥的步骤，预先捏合并混合。版权所有（C）2013，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method for placing abrasion-resistant concrete having a blending excellent in abrasion resistance and cost-effectiveness on a concrete structure receiving abrasion due to transportation sand gravel, such as a sand elimination bypass tunnel structure and a water conduit of a dam, and an abrasion-resistant concrete structure constructed by the method.SOLUTION: Abrasion-resistant concrete 12 is blended by calculating on the basis of an abrasion resistance index calculated by the sum of ratios of compression strength of compounding materials constituting the placed concrete to the volumes of the compounding materials. The abrasion-resistant concrete 12 is placed on a water flowing surface of a concrete structure 10, which receives abrasion due to transportation sand gravel.
