摘要
选用粉煤灰为主原料,适当添加水泥、硫酸钠、水玻璃及生物质灰等,通过蒸养方式制备一种新型生物填料。选择表观密度作为测定指标,以确定原料的最适用量及最适蒸养条件。结果表明,粉煤灰∶水泥∶硫酸钠∶水玻璃∶生物质灰的比例分别为8.0∶1.2∶0.13∶2.3∶0.2;蒸养温度110℃,蒸养时间9 h。
Fly ash is chosen as a main raw material in the experiment, and appropriate dose of the cement, sodium sulfate, sodium silicate and biomass ash, etc., were added. Through a way of steam curing, a new type of biologic padding was prepared. Apparent density is chosen as the measurement indicators to determine the most suitable amount of each raw material and the optimum process conditions. The results show that the optimum proportion of raw materials is fly ash∶cement∶anhydrous sodium sulfate∶sodium silicate∶biomass ash=8.0∶1.2∶0.125∶2.3∶0.2, the optimum process conditions is as follows： aging 1.5 h drying 2 h, steam curing at 110 ℃ for 10 h.
