本文结合流变力学理论,系统的研究了加入引气剂后水泥混凝土材料流变力学特性的变化。研究发现:引气剂显著改善混凝土工作性,对于低坍落度混凝土,提高了其流动性,而对于高流态混凝土,减少了其离析、泌水现象;引气剂能提高混凝土拌和物的塑性粘度,随着引气剂掺量的增大,塑性粘度也相应提高,在低坍落度混凝土中,屈服应力略有降低,在高流态混凝土中,屈服应力稍有增长。 Based on the theory of rheological mechanics, this paper systematically studies the rheological mechanical properties of cement concrete after adding air entraining agent. It is found that air-entraining agent can significantly improve the workability of concrete, improve the fluidity of low-slump concrete, and reduce the segregation and bleeding of high-fluidity concrete. Air-entraining agent can improve the concrete mix With the increase of air-entraining agent content, the plastic viscosity is also increased. In the low-slump concrete, the yield stress slightly decreases. In high-fluidity concrete, the yield stress increases slightly.
