基于粉煤灰掺量为60%与70%的净浆体系,掺入少量硫铝酸盐水泥,研究硫铝酸盐水泥掺量对该体系早期水化行为的影响。结果表明:在大掺量粉煤灰净浆体系中,掺入低于8%的硫铝酸盐水泥,凝结时间大为缩短,净浆体系抗压强度没有明显降低。 Based on the slurry with the fly ash content of 60% and 70%, a small amount of sulphoaluminate cement was mixed to study the influence of the dosage of sulphoaluminate cement on the early hydration behavior of the system. The results show that the incorporation of less than 8% sulphoaluminate cement in the high volume fly ash paste system shortens the setting time greatly and the compressive strength of the paste system does not decrease obviously.
