【摘要】：为满足低强度等级和高强度等级混凝土超高层泵送的特殊施工要求,通过三种不同类型的流变剂研究混凝土拌合物的流动性、粘度和填充性,通过坍落度、坍落扩展度、V型漏斗通过时间和T_(50)测试手段,评价流变剂对拌合物的调节性能,结果表明HJ流变剂适宜低强度等级混凝土,6A流变剂适宜高强度等级自密实混凝土。
[Abstract]:In order to meet the special construction requirements of low strength grade and high strength grade concrete pumping, the fluidity, viscosity and filling property of concrete mixture were studied by three different types of rheological agents. In order to evaluate the adjusting performance of rheological agent on mixing compound, the test means of collapse extension, V-shaped funnel passing time and Tass 50) showed that HJ rheological agent was suitable for low strength grade concrete and high strength grade self-compacting concrete, the results showed that HJ rheological agent was suitable for low strength grade concrete and high strength grade self-compacting concrete.
