主要研究了粉煤灰水泥二元胶凝体系在聚乙烯醇纤维和粉煤灰含量变化后抗压强度以及抗折强度的影响。结果表明：聚乙烯醇纤维对于粉煤灰水泥二元胶凝体系抗折强度的影响明显优于对抗压强度的影响。粉煤灰的掺入会降低立方体的抗压强度以及小梁的抗折强度，纤维含量均为0时，纯水泥浆体的28d抗折强度为粉煤灰含量为60%的浆体试块的3.17倍。
This paper mainly studies the effects of changing the content of PVA fiber and fly ash on the compressive strength and flexural strength of the fly ash cement binary cementing system. The results show that the effect of polyvinyl alcohol fiber on the flexural strength of fly ash cement binary cementing system is more significant than that of compressive strength. The addition of fly ash will reduce the compressive strength of the cube and the flexural strength of the trabecular beam. When the fiber content is 0, the 28d flexural strength of pure cement slurry is 3.17 times that of the slurry test specimen with 60% fly ash content.
