水泥粉煤灰砂浆瓦是国家建材局苏州混凝土水泥制品研究院和江苏省盐城市水泥制品厂协作,利用地方材料——细砂和粉煤灰,通过试验,研究成功的。其规格尺寸为380×240×12毫米,外观质量和物理力学性能都达到粘土平瓦的技术标准。1983年4月通过技术鉴定。经使用,反映甚好。一、原材料水泥:425号普通硅酸盐水泥; 砂:宿迁中砂,细度模数2.58; 阜宁细砂,细度模数1.16; The cement fly ash mortar tile is a collaboration between the Suzhou Concrete Cement Product Research Institute of the State Bureau of Building Materials and the Yancheng Cement Product Factory of Jiangsu Province. The local material—fine sand and fly ash—has been successfully tested through experiments. Its size is 380×240×12mm, and the appearance quality and physical and mechanical properties all reach the technical standard of clay flat tile. April 1983 passed the technical appraisal. Used, it reflects very well. First, the raw material cement: No. 425 ordinary portland cement; Sand: Suqian sand, fineness modulus 2.58; Funing fine sand, fineness modulus 1.16;
