Experimental Study on Anti-permeability Performance of High-performance Basalt Fiber Reinforced Concrete

Electric flux method was adopted in this paper to carry out experimental study on influences of fly ash and basalt fiber contents on chloride penetration resistance performance of high-performance concrete. First, influences of fly ash content were investigated by virtue of uni doped fly ash. Then, basalt fibers in diverse contents were added based on fly ash with an optimal content to achieve the optimal value of basalt fiber. Experimental results indicated that 30% was optimal for the value of fly ash content provided that slump of concrete and total electric flux were both taken into comprehensive consideration. As for the basalt fiber content, the total electric flux kept changing when it varied from 0 kg/m(3) to 1.6kg/m(3) and the maximum total electric flux could be obtained in the case that content of it reached 1.4kg/m(3).
