一种轻质建材的制备试验研究

Experimental Study on the Preparation of a Light Building Material

为提高建筑废弃物的利用,以建筑废弃物替代粉煤灰,进而制备一种轻质的泡沫混凝土轻质建材。为验证目标的可行性,在传统混凝土配比的情况下,将经活化后的建筑废弃物粉尘替代水泥和粉煤灰,构建新的泡沫混凝土,并通过试验验证上述替代对混凝土性能的影响。结果表明,上述方案得到的泡沫混凝土的性能优于同类产品,说明该方案具有一定的可行性。

In order to improve the utilization of construction waste,a lightweight building material with foamed concrete was prepared by replacing fly ash with construction waste.In order to verify the feasibility of the target,under the condition of traditional concrete proportioning,new building foam concrete was prepared with the activated construction waste dust instead of cement and fly ash,and the influence of the above substitution on the concrete performance was verified through tests.The results showed that the performance of the foam concrete obtained by the above scheme was better than that of the similar products,so the scheme is feasible.
