以磷尾矿作为填料制备泡沫混凝土的研究

Research on the phosphorus tailings used as filler in the preparation of foamed concrete

通过将云南磷化集团有限公司提供的反浮选磷尾矿用于泡沫混凝土的制备,研究了磷尾矿分别作为惰性和活性填料制备泡沫混凝土时质量百分比和抗压强度的联系。试验结果表明在泡沫混凝土产品达到A3.5B05级的抗压强度的情况下,磷尾矿作为惰性填料时,质量百分比最多可以达到6.9%,并且抗压强度和用量呈现良好的线性递减关系。在磷尾矿被煅烧后作为活性填料制备时,最多可达11.32%。煅烧后的磷尾矿的早期活性激发更加明显。

By preparing foamed concrete by using phosphorus tailings provided by Yunnan Phosphate Chemical Group Co.,Ltd., experiments were carried out to study the connections between the mass percent of the phosphorus railings as inert filler and active filler and compression strength.The results show that to reach the the compression strength of A3.5 B05 level standard,the highest mass percent of the phosphorus tailings as inert filler in the preparation of foamed concrete can reach 6.9% ,with a clear linear relationship between the mass percent of phosphorus tailings used as inert fillers and the compression strength of testing cubic.While being calcined using as active filler,the highest mass percent can reach 11.32%.The phosphorus tailings has much better early reaction activity after calcination.
