摘要
介绍了采用具有较低吸水率的轻集料(轻集料24h吸水率低于6%),通过一定的技术手段,配制出CL25 CL35符合泵送施工要求的轻集料混凝土,并采用正交试验法,分析了影响轻集料泵送混凝土强度和工作度的主要因素.
The authors introduce a lower absorb-water lightweight aggregate (Its capacity of absorb-water is lower than 6% in 24 hours) that was adopted in strength level of CL25-CL35 to fit pumping concrete through some technology. Then it analyzes the main relationship between its strength and workability of the lightweight aggregate pumping concrete and its components.
