摘要

对聚丙稀纤维和聚羧酸超塑化剂等新型材料合掺条件下混凝土的抗冲击性能、抗冲耐磨性能和抗裂性能进行了试验研究。研究表明

由于聚羧酸超塑化剂和粉煤灰的高效减水作用

使得该混凝土与硅粉混凝土相比具有胶材用量少

裂缝显著减少等特点。在聚丙稀纤维的作用下

混凝土抗冲击、耐磨损和抗裂等性能得到显著提高。

Abstract

The shock and wearing resistances and anti-crack performance of concrete blended with polycarboxylate superplasticizer and polypropylene fiber were studied.Results show that

compared with concrete added with silica fume

the high water-reducing effect of polycarboxylate superplasticizer and fly ash reduced the consumption of cementitious material and the amount of cracks decreased significantly.Together with the action of polypropylene fiber

the shock and wearing resistances and anti-crack performance of concrete enhanced remarkably.
