【摘要】:采用C30混凝土制備的再生粗、細(xì)骨料對(duì)不同強(qiáng)度等級(jí)及不同置換率再生混凝土進(jìn)行了抗透氣性能試驗(yàn)研究.結(jié)果表明:當(dāng)粗骨料為再生粗骨料、細(xì)骨料為天然砂時(shí),再生粗骨料置換率對(duì)再生混凝土透氣系數(shù)的影響較小;當(dāng)粗骨料采用天然碎石時(shí),再生細(xì)骨料置換率對(duì)再生混凝土透氣系數(shù)的影響較大,其透氣系數(shù)隨著再生細(xì)骨料置換率增加而增大.
[Abstract]:The permeability properties of recycled concrete with different strength grades and different replacement rates were studied by using recycled coarse and fine aggregate made of C30 concrete. The results show that when coarse aggregate is recycled coarse aggregate and fine aggregate is natural sand, the replacement ratio of recycled coarse aggregate has little effect on the permeability of recycled concrete, and when coarse aggregate is natural gravel, The replacement ratio of recycled fine aggregate has a great influence on the permeability of recycled concrete, and its permeability increases with the replacement rate of recycled fine aggregate.
