摘　　要：主要以废弃混凝土制得再生骨料,通过试验研究不同水胶比,不同颗粒级配的再生骨料制备的无砂混凝土的力学性能,透水性能,抗冻性能。试验结果表明由再生骨料制备的C20无砂混凝土的性能和水胶比及再生骨料的级配相关,其强度满足一般道路基层的需求,透水性能和抗冻性能良好。The concrete mainly made of recycled aggregate through the experiments to research the mechanics performance, the waterproof performance and the antifreeze performance of the recycled concrete under the different water/cement ratio and the different particle size distribution of the recycled aggregate.The result showed that the performance of the recycled concrete was about to the water/cement ratio and the different particle size distribution of the recycled aggregate, and it met the needs of the general road base on its strength, it also has good waterproof performance and antifreeze performance.
