Comparing and Analyzing Influence of Basalt and Carbon Fibers on the Cement Mortar

Basalt fiber is a kind of Environment-friendly inorganic fiber material. Compared with Carbon fibers, studied the influence on cement mortar compressive, flexural, anti-shrinkage properties between different content and lengths of basalt fiber. The results showed that mechanical properties of Basalt fibers cement mortar are better than that of Carbon fibers cement mortar at a certain content, It is well for basalt fibers as reinforcement of cement based materials. Basalt fibers reduce the fluidity of mortar and have a certain enhancement to cement mortar early strength, and short fiber is more obvious than long fiber mortar. Basalt fibers cement mortar improved anti-shrinkage of cement mortar between different age, but decreased it’s 28d strength
