在实际施工中往往出现许多可泵性差而耽误工程进度甚至影响混凝土质量等现象。本期特别策划一期影响泵送混凝土可泵性的因素,邀请行业专家针对此问题进行探讨。1.影响混凝土拌合物的可泵性有哪些因素?2.泵送机械和设备对混凝土泵送性有何影响?3.高性能和超高性能混凝土的泵送特点?4.如何改善混凝土可泵性,泵压不稳、堵塞、增强混凝土可泵性的具体措施是什么? In the actual construction often appear many pumpability is poor and delay the progress of the project even affect the quality of concrete and so on. In this issue, we plan a special project that will affect the pumpability of pumping concrete and invite industry experts to discuss this issue. 1. What are the factors that affect the pumpability of concrete mix? 2. How does the pumping machinery and equipment affect the pumpability of concrete? 3. Pumping characteristics of high performance and ultra high performance concrete? 4. How to improve the concrete What are the specific measures of pumpability, pump pressure instability, blockage, and enhance concrete pumpability?
