本文通过分析砼的可泵性,将砼的可泵性分解为砼的泵送流变性和稳定性两个方面。通过试验,就粉煤灰对砼的上述两个方面的影响进行了研究。由此进一步证实了粉煤灰对砼的可泵性的改善作用。
This paper analyzes the pumpability of the crucible and decomposes the pumpability of the crucible into two aspects of pumping rheology and stability of the crucible. Through experiments, the effects of fly ash on the above two aspects of helium were studied. This further confirms the improved effect of fly ash on the pumpability of the crucible.
