- Here is a study on the effects of hydrated cement on the compressive strength of autoclaved waste cement concrete (granite aggregate) lime system by simulating waste concrete. 模拟废混凝土进行蒸压处理,研究了水泥石对蒸压试样强度的影响。
- The effects of hardened cement on the compressive strength of autoclaved waste concrete samples of fine powder are less because the amount of hardened cement in ordinary concrete is more than 12.5 wt% (mass ratio). 由于普通混凝土的水泥用量按水化水泥量计算均超过12.;5%25;普通混凝土磨细制成蒸压试样的强度受废混凝土中水泥石量的影响很小。
- The gas anti-permeability and carbonation resistance of recycled concrete, which was prepared by using waste concrete as recycled coarse aggregate (RCA) and some cement and mineral additions as raw materials, were studied. 摘要以废弃混凝土为再生粗集料，再适当掺加一定量的水泥和矿物掺和料，制成再生混凝土。
- Mortars separated from the waste concrete were used to produce Portland cements, which were the high alite cement(HAC),the ordinary Portland cement(OPC) and the high belite cement(HBC) respectively. 利用从废弃混凝土中分离出来的废砂浆作为原料煅烧出了3种典型的水泥熟料,并对水泥熟料矿物组成和水泥物理性能、抗压强度、水化产物微观结构等进行了测试;
- Based on this, by using RO. 42.5R cement and recycled aggregate from artificial wasting concrete, RCA which reaching 50MPa strength are mixed successfully. 在此基础上，采用42.;5R普通硅酸盐水泥与人工破碎所得的再生骨料成功配制了强度为50MPa的再生混凝土。
