摘要
研究了粉煤灰在混凝土抗压强度、孔隙率及6h库仑电量变化过程中的最佳掺量,试验结果表明:粉煤灰掺量在20%~30%之间时,混凝土的强度能够取得较好的效果;粉煤灰掺量在40%左右时,混凝土的孔隙率降到最低,其抗氯离子渗透的性能达到最好。
The paper studies the optimal mixing amount of fly ash in the compressive strength, porosity and 6 hours coulomb electric quantity changes process of the concrete. Experimental results shows that, when the mixing amount of fly ash is between 20% and 30%, the concrete strength can achieve better effect, while the mixing amount of fly ash is about 40 %, the concrete porosity reduces to the lowest and the chloride-penetration resistance properties of the concrete reaches the best.
