引用本文摘 要：研究了陶粒掺量对透水混凝土孔隙率、抗压强度、透水性能及抗冻性能的影响。结果表明，随着陶粒掺量的增加，透水混凝土的连续孔隙率、透水系数逐渐增大，抗压强度逐渐减小。当陶粒掺量为30％时，透水系数最大，达到了3.10 mm/s，此时抗压强度为11.7 MPa。经过25次冻融循环后，当陶粒掺量达25%以上时，透水混凝土发生冻融破坏。 Abstract: The influence of ceramic content on the measured porosity, mechanical properties, water permeability and frost resistance of pervious concrete was studied. The results show that the measured porosity and permeability coefficient of pervious concrete increase gradually with the increase of ceramic content, while the compressive strength decreases. when the ceramic content is 30%, the water permeability coefficient is the largest, reaching 3.10 mm/s, and the compressive strength is 11.7 MPa. After 25 freeze-thaw cycles, when the ceramic content is 25% or more, the pervious concrete is damaged by freezing and thawing.
