通过对普通硅酸盐水泥、粉煤灰、钢纤维制备的不同试样的实验测试,测得了不同纤维含量的水泥基复合材料在高温后的质量损失、超声波波速损失及力学性质,结果表明:随温度升高,其质量损失百分比、波速减少百分比均增大,水泥基复合材料的抗压、抗折强度不断减小。

The paper applies common portland cement,fly ash and steel fiber for fabricating various fiber parameters testing examples,and meas-ures the quality loss,supersonic velocity loss and mechanical properties of cement-based composites with different fiber contents after high temper-ature. Results show that:with the temperature rising,both the quality loss percentage and the supersonic velocity reducing percentage increase, cement-foundation composite material pressure-resisting strength and bending-resisting strength continuously reduce.
