通过正交试验研究设计孔隙率、水胶比、柔性聚丙烯纤维掺量、丁苯橡胶乳液掺量对喷射型多孔混凝土物理力学性能的影响规律，得到各因素对喷射型多孔混凝土坍落度、28 d抗压强度、有效孔隙率的影响程度，并优选出了水库消落区用喷射型多孔混凝土的配合比。

Orthogonal tests examined how design porosity,water-cement ratio,polypropylene fiber content and butadiene rubber emulsion content affect shotcrete properties.They determined each factor's importance for slump,28-day compressive strength and effective porosity.Desig...MORE Orthogonal tests examined how design porosity,water-cement ratio,polypropylene fiber content and butadiene rubber emulsion content affect shotcrete properties.They determined each factor's importance for slump,28-day compressive strength and effective porosity.Design porosity had the greatest impact on shotcrete slump,streng...
