通过对16组粉煤灰再生混凝土试件的试验,考虑了粉煤灰与再生骨料的影响,经多元回归计算建立了灰水比、再生骨料取代率、粉煤灰取代率与28 d抗压强度之间的关系,并探讨了灰水比、粗骨料压碎指标、粉煤灰取代率与抗压强度的关系。对普通混凝土的鲍罗米公式进行修正,得到了适用于粉煤灰再生混凝土配合比设计的鲍罗米公式。
Through the test of 16 fly ash recycled concrete specimens, the influence of fly ash and recycled aggregate was considered, and the gray-water ratio, the replacement ratio of recycled aggregate, the replacement rate of fly ash, Compressive strength of the relationship between the gray water ratio, coarse aggregate crushing indicators, fly ash replacement rate and compressive strength of the relationship. The Bowron formula of ordinary concrete is modified, and the Bowron formula which is suitable for the mix design of fly ash recycled concrete is obtained.
