Research of porosity and the size effect on the mechanical behavior of porous concrete

根据透水混凝土的结构特征,本文对其配制参数和配合比计算方法进行了研究,验证了以总孔隙率为第一设计参数,抗压强度为第二参数的配合比设计方法。试验证明:采用该方法制备的透水混凝土具有良好的透水性和强度,基本能够达到最初的设计要求。研究了骨料粒径、孔隙率和尺寸效应对透水混凝土力学性能的影响,为透水混凝土工程应用提供技术支持。

According to the structural characteristics of pervious concrete, with the ratio of its preparation parameters and calculation methods, it was verified that the first design parameters of the total porosity, compressive strength as the second parameter of the mix design method. Through experiments proved: The permeability of concrete prepared by this method has good permeability and strength, to achieve the original design requirements. Study the aggregate particle size, porosity, and size effect on the mechanical behavior of porous concrete, to provide technical support for the permeable concrete engineering application.
