研究了再生骨料取代率和牡蛎壳粉取代率对透水混凝土透水性能和抗冻性能的影响。结果表明:透水混凝土的抗冻性能随着再生骨料取代率和牡蛎壳粉取代率的增加而降低,当再生骨料取代率为100%且牡蛎壳粉取代率≤40%时,透水混凝土的透水性能满足相关规范要求,抗冻等级达到D25。
The effects of the replacement rate of recycled aggregate and the replacement rate of oyster shell powder on the water permeability and frost resistance of pervious concrete were studied. The results show that the frost resistance of pervious concrete decreases with the increase of the replacement rate of recycled aggregate and the replacement rate of oyster shell powder. When the replacement rate of recycled aggregate is 100% and the replacement rate of oyster shell powder is less than or equal to 40%, the water permeability of pervious concrete meets the requirements of relevant specifications, and the frost resistance level reaches D25.
