摘要
采用特细砂作骨料 ,通过改性 ,配制出C5 0高强混凝土。运用双掺技术 ,改善了混凝土的和易性 ,并通过调整碎石粒径、砂率、坍落度 ,实现了超高程混凝土一泵到顶。
C50 high-strength concrete was successfully prepared using improved extra fine sand as aggregate, and was pumped to a super\|high elevation through adjusting size of crushed stone,sand percentage and slump and meliorating the workability of concrete using two kinds of admixture.
