- In an examination recycled aggregate used instead of a normal macadam and sand 1... 试验结果,100%25全再生混凝土与普通混凝土试件相比,抵抗中性化能力差,中性化几乎以3倍的速度增长。
- The percentages of recycled aggregate are 0,30%,50%,70% and 100%. The same slump of each concrete was obtained by adjusting the quantity of water. 试验中再生粗骨料的掺入量分别为0,30%25,50%25,70%25和100%25,通过调节用水量使各组混凝土达到相同的坍落度。
- Regardless of the age, compressive strength of recycled aggregate precoating is around 11% higher than that of recycled concrete. 裹浆再生粒料混凝土抗压强度不论龄期长短皆较未裹浆再生粒料混凝土高约11%25。
- The result indicates pre-wetted aggregate can improve workability and decrease slump loss due to large water absorption of recycled aggregate. 结果显示,预湿可有效改善再生混凝土工作性以及坍度损失过高的问题;
- It was found that the inferable compressive strength coincides well with the measured values for recycled aggregate concrete. 基于本文获得的再生混凝土的超声声速和回弹值试验结果,建立了再生混凝土的测强曲线。
- 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。
- The recycled aggregate precoating can enhance aggregate specific gravity, reduce abrasion and water absorption rate.It does not have a significant effect in anti-sulfur corrosion. 裹浆再生粒料可提高粒料比重、降低磨耗率及吸水率,抗硫酸盐侵蚀效益较不明显。
