Phosphogypsum plastering mortar and preparation method thereof
The invention discloses phosphogypsum plastering mortar and relates to the field of building materials. The ardealite concrete comprises the following raw materials in parts by weight: 70-75 parts ofardealite powder, 1.5-2.5 parts of slaked lime, 2-3 parts of Portland cement, 6-8 parts of vitrified micro bubbles, 3-5 parts of quartz sand, 9-11 parts of heavy calcium carbonate powder, 0.15-0.25 part of an industrial mildew preventive, 0.15-0.25 part of an organosilicon waterproofing agent, 0.15-0.25 part of starch ether, 0.15-0.25 parts of plant protein retarder, 0.15-0.25 parts ofpolyacrylamide, and 0.15-0.25 parts of cellulose with the viscosity being higher than 200,000 units. The industrial mildew preventive and the organic silicon waterproofing agent are both powder. The preparation method comprises the following steps: 1, preparing the raw materials in parts by weight; 2, mixing phosphogypsum powder and slaked lime to obtain a mixture, and then finely grinding the mixture to enable the specific surface area of the mixture to reach 600-620 m2/kg; 3, uniformly mixing the finely ground mixture with other raw materials to obtain the phosphogypsum plastering mortar. The phosphogypsum plastering mortar provided by the invention has the advantages of high strength, good constructability, no hollowing, no cracking and the like.
本方案公开了建筑材料领域的一种磷石膏抹灰砂浆，包括的原料及其重量份数为：磷石膏粉70～75份、消石灰1.5～2.5份、硅酸盐水泥2～3份、玻化微珠6～8份、石英砂3～5份、双飞粉9～11份、工业防霉剂0.15～0.25份、有机硅防水剂0.15～0.25份、淀粉醚0.15～0.25份、植物蛋白缓凝剂0.15～0.25份、聚丙烯酰胺0.15～0.25份、粘度20万个单位以上的纤维素0.15～0.25份，工业防霉剂和有机硅防水剂均为粉剂。制备时包括以下步骤：一、按重量份数准备原料；二、将磷石膏粉和消石灰混合得到混合料，然后精磨混合料使其比表面积达到600m2/kg～620m2/kg；三、将精磨后的混合料与其他原料混合均匀，得到磷石膏抹灰砂浆。本申请中的磷石膏抹灰砂浆具有强度高、施工性好、不空鼓、不开裂等优点。
