摘要
以废砖粉为主要原材料,普通硅酸盐水泥为胶凝材料,配以废泡沫塑料以及各种外加剂,经发泡剂发泡,在常温、常压条件下养护,制备新型轻质墙体材料。采用正交试验,考察水泥、脱硫石膏、废泡沫塑料掺量和固液比对材料密度、吸水率、强度的影响,得出最优配比为水泥15%,脱硫石膏20%,废泡沫塑料9 g,固液比2.5。
A kind of new light weight wall material,which was made of crushed brick as a main raw material and P＇O ce- ment as a eementious material,spent foam plastic and some admixtures were added,is prepared under the ordinary temperature and pressure condition. Through orthogonal test,the influence of the mixing amount of cement,desulfurized gypsum, spent foam plastic and solid-liquid ratio on bulk. density,water absorption and strength of material is invested. And the optimal proportion is ob- tained： cement 15%, desulfurized gypsum 20%, spend foam plastic 9 g and solid liquid ratio 2.5.
