摘要：用10%、30%和50%的废弃混凝土骨料替代天然骨料制备再生透水混凝土，并对其强度、透水性能和耐久性能进行了研究。结果表明，再生透水混凝土存在最优水灰比，当再生骨料掺量为10%、30%和50%时，透水混凝土的最优水灰比分别为0.40、0.40和0.45；随着再生骨料掺量和粒级的增加，再生透水混凝土的抗压强度、抗折强度降低，透水性能增强；5%硅粉会一定程度上提高透水混凝土的强度，但会对其透水性能产生不利影响；再生骨料的掺加会降低透水混凝土的长期耐久性能。 Abstract: Recycled permeable concrete was prepared by replacing natural aggregate with 10%, 30% and 50% recycled concrete aggregate, and its strength, permeability and durability were studied. Results show that the optimal water-cement ratio is 0.40, 0.40, 0.45 respectively when the addition of recycled aggregate is 10%, 30%, 50%. With the increase of recycled aggregate content and particle size, the compressive strength and flexural strength of recycled permeable concrete decrease, and the permeability of recycled permeable concrete increases. The incorporation of 5% silica powder can improve the strength of permeable concrete to a certain extent, but it will have an adverse effect on its permeability performance. The addition of recycled aggregate canl reduce the long-term durability of permeable concrete.
