摘要
采用正交试验法研究了单掺粉煤灰、单掺矿渣粉及碳化复合作用对植生混凝土抗压强度和碱度的影响。结果显示:粉煤灰能够改善植生混凝土的p H值,但抗压强度下降明显;适量的矿渣粉不仅可改善植生混凝土的pH值,同时还能提高其抗压强度;碳化时间对植生混凝土抗压强度和p H值的影响较小。分析表明粉煤灰掺量为0,矿渣粉掺量为25%,碳化时间为3d时,植生混凝土兼具较好的抗压强度和pH值。
The effects of fly ash, slag powder and carbonation on the compressive strength and alkalinity of vegetation concrete are studied by orthogonal test. The results show that fly ash can improve pH value of the vegetation concrete, but the compressive strength decreases significantly, the amount of slag powder not only improves the pH value of the vegetation concrete, but also improves the compressive strength; carbonization time had little effect on compressive strength and pH value of the vegetation concrete. The results show that the vegetation concrete had the best compressive strength and pH value with 0% of fly ash, 25% of slag powder and 3d of carbonation time.
