Phosphogypsum-based waterproof curb and preparation method thereof
The ardealite-based waterproof curb is prepared from the following raw materials in parts by weight: 87 to 95 parts of phosphorus building paste powder, 3 to 8 parts of seven-hole sand, 0.2 to 0.5 part of a water reducing agent, 0.05 to 0.12 part of a retarder and 0.2 to 0.5 part of a water repellent. The prepared curb is high in compressive strength and can be used on a pouring site at present, the problems of breakage rate and appearance quality in the transportation process are solved, the defects that other gypsum-based curbs crack and soften when encountering water are effectively overcome, the moisture resistance and firmness are improved, the service life is prolonged, and the production cost is reduced. The quality of gypsum products is improved; and the service life of the gypsum-based curb is prolonged.
本发明公开了一种磷石膏基耐水路缘石，由以下重量份的原料制成：磷建筑膏粉87～95份、七眼砂3～8份、减水剂0.2～0.5份、缓凝剂0.05～0.12份、憎水剂0.2～0.5份。本申请制得的路缘石抗压强度较高，可以现在浇筑现场使用，解决运输过程中的破损率及外观质量问题，还有效地解决了其他石膏基路缘石遇水开裂，软化的缺陷，增加防潮性和牢固性及使用年限，提升石膏类产品质量和石膏基路缘石的使用年限。
