摘要
采用温度应力试验机(TSTM)试验方法,对比研究了HCSA膨胀剂在普通水泥混凝土与高掺量粉煤灰混凝土中的作用效果。结果表明:在本试验条件下,粉煤灰与HCSA膨胀剂复合使用,发挥出超叠效应。
Comparison of effect testing results of HCSA expansive agent in normal concrete and high volume fly ash concrete was presented in this paper. The results indicated that combination of fly ash and HCSA expansive agent may appear a synergistic effect on the concrete under the set condition.
