摘要
为了提高我国工业副产物磷石膏的综合利用率,减小环保压力,研究探索磷石膏的利用途径成为目前一个紧要的问题。通过归纳前人在建筑墙体砖方面对磷石膏的研究,总结了我国磷石膏在建筑墙体砖上的学术成果,分析了磷石膏墙体砖的制备工艺方法。国内目前制备出的磷石膏砖的抗压强度可达到10MPa以上。
In order to improve the comprehensive utilization rate ot industrial by--proauct-- pnospnogypsum （PG） and reduce environmental pressure,, to study the utilization of PG becomes a burning issue currently. The authors of this paper summarizes the previous researches on PG applied in architecture wall-- bricks, and also sums up the academic achievements in China, In this paper, it analyzes the preparation technologies of PG wall--bricks. At preaent in China, the compressive strength rate of the prepared PG wall--bricks can achieve more than 10 MPa.
