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.
