초록

In this study, it is investigate to influence on tile dispersion of fiber and the flowability of matrix of type and amount of superplasticizer, velocity agent, mineral admixture and steel fiber to improve for construction performance of steel fiber reinforced cementitious composites. As for the test results, it was found that the dispersion of fiber and the flowability of matrix in steel fiber reinforced cementitious composites can improve by using of properly amount and combination of superplasticizer, velocity agent, mineral admixture. Furthermore, It show that the aspect ratio of steel fiber affect the construction performance of fiber reinforced cementitious composites, and the improvement for construction performance is the more effective the smaller aspect ration of steel fiber.
