Abstract

Abstract

The influence of compounding polypropylene fiber and expansion on flexure strength, impermeability and the shrinkage deformation is studied.The experimental results show the comparing with the single effect of either polypropylene fiber or expansive agent, the compounding of them can enhance 28 days flexure strength by 7^5% and 9^9% and reduce the permeability height by 46% and 61% separately and it can also sharply increase the anti-cracking property.The polypropylene fiber can obviously restrict the 7～14 days expansion of expansive concrete.
- polypropylene fiber,
- expansive concrete,
- anti-cracking impermeability,
