Phosphogypsum-based building material as well as preparation method and application thereof
The invention belongs to the technical field of engineering materials, and provides an ardealite-based building material and a preparation method and application thereof, the ardealite-based building material is prepared from the following raw materials by mass: 100-200 parts of carbonized dregs, 5-8 parts of sodium oleate, 40-50 parts of aggregate, 20-30 parts of a coupling agent, 350-450 parts of ardealite, 40-60 parts of hexadecyl trimethoxysilane, 30-35 parts of cement, and 80-90 parts of water. The ardealite and carbonized medicine residues are comprehensively utilized, the medicine residues contain a large number of micropore structures after being carbonized, the medicine residues are modified through sodium oleate, and a large number of groups can be grafted; phosphogypsum and hexadecyltrimethoxysilane are mixed, and organic groups can be connected to the surface of phosphogypsum to the maximum extent; the medicine residues and the ardealite can be tightly and firmly combined together in a group combination manner, so that the looseness of the material is fundamentally avoided, and the compressive strength and the thermal insulation property of the material are improved.
本发明属于工程材料技术领域，提供了一种磷石膏基建筑材料及其制备方法和应用，该材料由包含下列质量份数的原料制备得到：碳化药渣100～200份、油酸钠5～8份、骨料40～50份、偶联剂20～30份、磷石膏350～450份、十六烷基三甲氧基硅烷40～60份、水泥30～35份、水80～90份。本发明将磷石膏和碳化药渣综合利用，药渣经过碳化后，其含有大量的微孔结构，通过油酸钠对药渣进行改性，能接枝大量的基团；磷石膏和十六烷基三甲氧基硅烷进行混合处理，能在磷石膏表面最大限度的连接上有机基团；药渣和磷石膏通过基团结合的方式能紧密、牢固的结合到一起，从根本上避免了材料的松散，提高了材料的抗压强度和保温性能。
