| Abstract: | This paper studies the effect of acrylic fibre on improving the performance of cracking-resistance in mortar/concrete,and analyzes the mechanism of the cracking-resistance.The result shows that acrylic fibre have been added to conventional concrete at low volumes and remarkably reduce the effects of plastic-shrinkage cracking,which will be more and more widly used in constructional engineering. |

| Keywords: | acrylic fibre cement based composites cracking-resistance performance mechanism |
