Magnesia sulfoaluminate cement composition as well as product and manufacturing method thereof
The invention relates to a magnesia sulfoaluminate cement composition as well as a product and a manufacturing method thereof. The composition comprises light calcined magnesia, magnesium sulfate heptahydrate, calcined bauxite, phosphoric acid or phosphate and water. The composition and the cement product thereof have the advantages that (1) the cement is high in strength; (2) the alkalinity of the cement is low; (3) the cement can utilize low-grade bauxite, so that effective utilization and reasonable allocation of resources can be realized; (4) the service lifetime of the cement product is long; and (5) the cement can be directly compounded with a fiber material to prepare fiber reinforced magnesia cement products meeting various requirements.
本发明涉及一种镁质硫铝酸盐水泥组合物及其制品和制作方法。所述镁质硫铝酸盐水泥组合物包括轻烧氧化镁、七水硫酸镁、煅烧铝矾土、磷酸或磷酸盐和水。所述镁质硫铝酸盐水泥组合物及其水泥制品的优点包括：(1)所述水泥强度高；(2)所述水泥碱度低；(3)所述水泥可利用低品位的铝矾土，能够实现资源的有效利用和合理配置；(4)所述水泥制品的使用寿命长；(5)所述水泥能与纤维材料直接复合，制作成满足各种需要的纤维増强镁水泥制品。
