【摘要】：为了获得一种以粉煤灰和废旧泡沫塑料为原料的新型节能墙体建筑材料,以石灰和石膏为粉煤灰活化剂,废旧聚苯乙烯(EPS)颗粒作为保温材料的组成部分,制备了墙体砌块材料。利用X射线衍射、扫描电镜、热重-差热分析等方法研究了墙体砌块材料的最佳配比及老化水化机理。结果表明:当粉煤灰与石灰的配比为10%，石膏用量5%，粉煤灰用量20%-25%，改性EPS用量2.5%，砌块材料导热系数0.505 W/(m·K)，隔热性能、施工性能、耐久性能、耐候性能均良好。
In order to get a new kind of energy-saving wall building materials made from fly ash and waste styrofoam,a wall block materials was made using lime and gypsum as the activating agents of fly ash and waste polystyrene(EPS) particles as a constituent of the insulating material.The optimum ratio and the age hydration mechanism of wall block materials were studied using X-ray diffraction,scanning electron microscope and thermogravimetry-differential thermal analysis.The results show that when the ratio of fly ash to lime is 10% and that to gypsum is 5%,the dosage of fly ash is 20%-25% and that of modified EPS is 2.5%,the thermal coefficient of the block material is 0.505 W/(m·K).The heat insulation property,construction property,lasting quality and weatherability are all good.
