采用粉煤灰等量替代水泥进行改性，研究了不同粉煤灰掺量、不同骨料粒径对透水混凝土孔隙、透水性能及力学性能的影响，从微观层面揭示粉煤灰对透水混凝土的作用机理。结果显示，当粉煤灰掺量为20%时，透水混凝土渗透性能满足工程要求，其60d抗压强度有明显提高。

The equal replacement of cement by fly ash is tested, the influences of different fly ash content and aggre-gate sizes on porous concrete's pores, permeability and mechanical properties are studied, and the microscopic mechani-cals are further revealed. The results show that the permeability of porous concrete mixed with 20%fly ash can meet engi-neering requirement, and the 60 days compressive strength of such concrete increases significantly.
