中国科技核心期刊 发泡水泥板废料制备免烧免蒸砖的 试验研究 纪前仁，曹晓梅，孙寅斌 （ 江苏尼高科技有限公司，江苏常州 213141） 摘 以发泡水泥板废料代替骨料和部分粉煤灰，采用压制成型方法制备免烧免蒸砖，对不同掺量发泡板废料和不同掺量水 要： 泥进行了对比试验，同时比较了不同石膏、成型水用量、外加剂及养护制度对免烧免蒸砖抗压强度的影响。结果表明，发泡板废料掺 量可高达50% ，成型水用量13%，成型压力4 MPa 左右，制备的免烧免蒸砖抗压强度可达 12 MPa 以上，符合JC 239—2001《粉煤灰 砖》的要求；水泥掺量的增大有利于提高免烧免蒸砖强度；热养护与标准养护20 d 强度相当。 废料；免烧免蒸砖 关键词：发泡水泥板； 中图分类号：TU522.1 文献标识码：A 文章编号：1001-702X （2013）07-0046-04 Experimental investigation on non-burned and non-autoclave bricks with foam cement panel waste JI Qianren ，CAO Xiaomei，SUN Yinbin （JiangSu NIGAO Science and Technology Co. Ltd. ，Changzhou 213141 ，Jiangsu ，China） Foam cement panel waste was used to replace aggregate and some fly ash in preparation of non-burned and non- Abstract ： autoclave bricks by compression moulding. Comparative study in different content of foam cement panel waste and cement was car － ried out ，and the effects of different gypsum ，forming water content ，admixture and curing system on compressive strength of non- burned and non-autoclave bricks were also investigated. The results show that the non-burned and non-autoclave bricks with com － pressive strength of more than 12 MPa can be prepared in the condition of 4 MPa pressure ，the maximum mixing amount of foam cement panel waste up to 50% and the 13% forming water content ，meeting the requirements in standard JC 239—2001 ；Increase the content of cement can increase the compressive strength of non-burned and non-autoclave bricks ；the 20 d compressive strength of heating curing and standard curing are concord in the basic line.
