一种磷石膏混凝土及其制备方法

Abstract

一种磷石膏混凝土及其制备方法,属于磷石膏综合利用的技术领域。本发明采用磷石膏作为掺合料替代部分水泥制备混凝土,所述原料的质量以每立方米磷石膏混凝土计:磷石膏19.5~97.5kg、水泥292.5~370.5kg、减水剂7.8~8.97kg、水150~165kg、砂子880~960kg、石子870~960kg。制备方法包括以下步骤:先将磷石膏晾干或烘干;对磷石膏进行粉磨分级,得到粒径小于80μm的颗粒超过98%的磷石膏粉料;按质量称取原料,搅拌均匀,得到磷石膏混凝土。本发明制备的磷石膏混凝土能达到C30混凝土的技术指标要求,其抗渗性能可达到P12抗渗等级要求。本发明可以大量利用磷石膏,解决磷石膏堆存问题。
The invention discloses ardealite concrete and a preparation method thereof, belonging to the technical field of comprehensive utilization of ardealite. In the invention, ardealite is used as an admixture and partially replaces cement to prepare concrete. Every cubic meter of ardealite concrete comprises the following raw materials: 19.5-97.5kg of ardealite, 292.5-370.5kg of cement, 7.8-8.97kg of water reducing agent, 150-165kg of water, 880-960kg of sand and 870-960kg of stone. The preparation method comprises the following steps of firstly airing or drying the ardealite; grinding and classifying the ardealite to obtain ardealite powder with a particle size less than 80 microns and over 98% of particles; weighing the raw materials according to the mass, and stirring uniformly to obtain the ardealite concrete. The prepared ardealite concrete can meet the requirements for the technical indexes of C30 concrete, and the impervious performance thereof can meet the requirements of P12 impervious level. In the invention, a large quantity of ardealite can be utilized, and the problem of ardealite stockpiling is solved.
