新型混凝土速凝剂的性能试验研究
Experimental Study on the Performance of Alkali-free Liquid Concrete Accelerators
摘要
Abstract
Because the alkali -free liquid concrete accelerator is able to overcome many defects of traditional concrete accelerator, it has been going to replacing the traditional accelerator and becoming the representative of new accelerators. In order to understand the performances of alkali-free accelerator, a number of domestic and foreign alkali-free accelerators are selected to test their performances, in which, a new test method is explored based on European standards. The performances of alkali-free accelerators are also compared with traditional powder alkaline and liquid low-alkali accelerators. The experimental results show that (a) new accelerators are significantly superior to the traditional accelerators in setting time, early compressive strength, growth rate of late compressive strength and compressive strength ratio; and (b) the compressive strengths of new and traditional accelerators in each ages are satisfied with the logarithmic growth relationship.关键词
