聚丙烯纤维轻骨料混凝土抗压强度试验研究
|
摘要
混凝土自重一般情况较大,为了提高其韧性、抗裂性和耐久性,在实际工程研究的基础上,本文提出了聚丙烯纤维自燃煤矸石轻骨料混凝土的配合比设计方法。运用该方法对混凝土进行配合比试验,得出聚丙烯纤维轻骨料混凝土的抗压强度试验数据,为聚丙烯纤维自燃煤矸石轻骨料混凝土的工程应用提供必要的技术支持。
The weight of concrete is generally large. In order to improve its toughness, crack resistance and durability, based on the actual engineering research, this paper proposes a mixing ratio design method of polypropylene fiber self-igniting coal gangue lightweight aggregate concrete. Using this method to test the concrete mix ratio, the compressive strength test data of polypropylene fiber lightweight aggregate concrete is obtained, which provides necessary technical support for the engineering application of polypropylene fiber self-igniting coal gangue lightweight aggregate concrete.
