Water Absorption of Basalt Fiber Reinforced Cement
Chopped basalt fibers untreated and treated by silane coupling agent were used to modify cement sample, in order to reduce water absorption. After fully soaked in water, the water content went up with the increase of fiber content. When the fiber content was 2.5Kg.m-3, the water absorption ratios of the samples reinforced by fibers without and with silane treatment were 4.83% and 5.44%, which were 57.1% and 39.5% less than the control group. This indicates that the fiber content was significant to water sorption and the influence of silane treatment is unnecessary for the reduction of water sorption.
