Abstract

A technology for producing burning-free building blocks includes such steps as mixing phosphorus ore tailings or waste casting dregs or metallurgical slags with cement and water, uniformly stirring to stickiness, press mocelding, and curing at 0-50 deg.C for 60 hr or more. Its advantages are low cost decreased by 25-30%, high strength and aesthetic appearance.
一种免烧砌块的生产方法,将磷尾矿渣或铸造废渣或冶金炉渣、水泥、水混合搅拌均匀至发粘后,投入模具中,压制成型,在温度为0—50℃的环境下,养护不少于60小时。比煤渣砌块生产成本降低了25—30%,且产品外表美观,强度高,原料易得,省土节能,为废矿渣的综合利用找到了一条有价值的途径,创造了财富,减少了磷尾矿渣、铸造废渣、冶金炉渣的堆积占地和对环境的污染,有明显的经济效益和社会效益。
