摘要：

Porous concretes have been used as various construction materials. However, the flexural strength of the porous concrete is lower than that of the ordinary cement concrete because of its porous structure. The flexural strength of the porous concrete may be improved by fiber reinforcement. The purpose of this study is to investigate mix proportioning factors and strength properties of fiber-reinforced porous concretes. The fiber-reinforced porous concretes are prepared with various vinylon fibers contents and continuous voids contents, and subjected to compressive strength and flexural strength tests. The test results show that the percentage of absolute volume of the mixture of fibers and aggregates is an important factor in the mix design of the fiber-reinforced porous concrete to give the prescribed voids. The compressive and flexural strengths of the fiber-reinforced porous concretes are increased with an increase in the cement content and fibers content. The strength control factors of the fiber-reinforced porous concrete calculated from the volume percentage of the cement mortar as a binder, vinylon fibers and continuous voids are proposed.
