摘要
研究了灰集比、水灰比和矿物掺合料对植生型多孔混凝土性能的影响,分析了相应的影响规律。试验结果表明,植生型多孔混凝土灰集比应控制在1:6~1:7之间,且水灰比为32%~35%之间较适宜;矿物掺合料对植生型多孔混凝土pH值的影响次序:粉煤灰﹥硅灰﹥矿渣,其最适掺合比例:粉煤灰15%~20%,矿渣10%~15%,硅灰4%~5%。
The effects of the cement-aggregate ratio,water-cement ratio and mineral admixtures on properties of plant-growing porous concrete are studied through experiments.The results indicate show that the cement-aggregate ratio of plant-growing porous concrete should be controlled between the 1:6-1:7 ratio,and water-cement ratio of 32%-35% is more appropriate.The effective order of the mineral admixture on pH of plant-growing porous concrete is as following : fly ash﹥silica fume﹥slag powder,and the optimum addition ratio: fly ash ratio is 15%-20%,slag powder ratio is 10%-15% and silica fume ratio is 5%-5%.
