The Reasonable Amount of Polypropylene Fiber on Low-Intensity Manufactured Sand Concrete in the Case of Fixed Powder Paste

Abstract:

Compared with the river sand, manufactured sand’s particle type and gradation is relatively poor and the surface is mat .The manufactured sand also has a big effect on the workability of concrete. In this paper,the Equivalent powder paste’s volume of manufactured sand concrete was determined according to Mehta and Aitcin’s ideas for the preparation of HPC,at the same time,the equivalent powder paste volume is assumed as the cement paste volume in the experiment. The influence of polypropylene fiber on Manufactured sand concrete’s workability and Compressive strength were researched in the case of fixed powder paste .
