Experimental Study on the Anti-Cracking Property of Basalt Fiber for Cement-Based Materials

Abstract

Basalt fiber has the advantages of non-pollution and omnipotence, and will be widely used in the 21st Century. Therefore, more and more attention is paid on experimental research on the basalt fiber in the world. First,according to the requirements of the fibers used in the cement-based materials, the contrast testing of the plastic shrinkage between fiber cement mortar and pure mortar was made. The experimental results showed that basalt fiber , polypropylene fiber and polyacrylonitrile fiber can be preliminarily chosen as reinforced fibers in cement-based materials. Finally, taking both characteristics of basalt fiber and the increase of cement-based materials costs into account, it can be drawn that top priority should be given to the basalt fiber rather than to other fibers for cement-based materials.
