为拓展磷石膏的产业化应用,该文以磷石膏为主要原料,通过与矿渣、钢渣和少量水泥混合,研制具有优良性能的过硫磷石膏水泥,并且运用此水泥制备砌筑用免烧砖。提出了磷石膏水泥基砌筑用免烧砖的制备工艺,通过改变砌筑用免烧砖的养护条件,研究了不同养护制度对砌筑用免烧砖的力学性能,水化产物,微观结构的影响。
In order to expand the industrial application of phosphogypsum, phosphogypsum as the main raw material, through the slag, slag and a small amount of cement mixed to develop excellent performance of the over-phosphogypsum cement, and the use of this cement masonry brick . Proposed phosphogypsum cement-based brick masonry brick preparation process, by changing the masonry brick curing conditions, studied the different curing system on masonry brick with mechanical properties, hydration products, microstructure Impact.
