摘要
通过对粉煤灰掺量不同的再生粗骨料取代率为30%和50%的粉煤灰再生混凝土进行回弹检测其抗压强度,得出随着粉煤灰掺量的增加,粉煤灰再生混凝土的回弹值呈先下降后上升的趋势,为推测粉煤灰再生混凝土的专用测强曲线和回归方程提供了基础理论。
Through the different fly ash replacement ratio of recycled coarse aggregate 30% and 50% fly ash recycled concrete for the compressive strength of the rebound test, obtained results with the increase of fly ash obtained, the rebound value of fly ash was reduced initially and then increased, provided the basis for theory of speculating that ash recycled concrete and the curve for the regression equation.
