配制出C80以上强度的混凝土,对于当今的科技技术却不是难题。但配制出的混凝土能否满足泵送要求,却是施工中的难点。如何优化高强混凝土的配比,使其即能满足泵送要求,又能在龄期到后满足强度要求。 Formulating concrete with strength above C80 is not a problem for today’s technology. However, the preparation of concrete can meet the pumping requirements, but it is the construction of the difficulties. How to optimize the ratio of high-strength concrete, so that it can meet the pumping requirements, but also to meet the strength requirements after the age.
