摘要
含粗骨料超高性能混凝土(粗骨料UHPC)可兼顾超高强度和超高耐久性能,进一步降低收缩,但自收缩较大的问题仍未解决。文章主要研究了高吸水性树脂(SAP)在0.1%、0.15%和0.2%胶凝材料用量下,相对于膨胀剂对粗骨料UHPC工作性、自收缩以及力学性能的影响。
Ultra-high performance concrete with coarse aggregate(coarse aggregate UHPC)can take into account both ultra-high strength and ultra-high durability performance,and further reduce shrinkage,but the problem of large self-shrinkage has not been solved.This article mainly studied the effects of superabsorbent polymer(SAP)on the workability,autogenous shrinkage and mechanical properties of CA-UHPC compared to expansion agents at 0.1%,0.15%,and 0.2%of cementitious material masses.
