Raw material formula for inorganic terrazzo
The invention discloses a raw material formula for inorganic terrazzo. The raw material formula is composed of coarse aggregate, fine aggregate, a cementing material, pigment and additives, wherein the coarse aggregate comprises black sand with a size of 6-8 meshes, black sand with a size of 8-16 meshes and ordinary sand with a size of 8-16 meshes; the fine aggregate is composed of ordinary sand of three specifications, namely common sand with a size of 30-50 meshes, common sand with a size of 50-70 meshes, the common sand with a size of 70-120 meshes; the cementing material comprises 22-33% of ordinary silicon, 5-10% of mineral powder, 3-8% of silica fume and 3-10% of special cement; the pigment is carbon black; and the additives comprise a polycarboxylate high-performance water reducingagent, 1-3% of hydroxypropyl methyl cellulose, a GX-570 coupling agent, a defoaming agent and semi-hydrated gypsum. With the raw material formula, finished terrazzo is smoother in surface and small ininternal porosity, and has improved strength and durability.
本发明公开了一种无机板水磨石的原料配方，由粗集料、细集料、胶凝材料、颜料以及外加剂组成，粗集料中包括6~8目的黑砂、8~16目的黑砂以及8~16目的普砂，细集料由三种规格的普砂组成，分别为30~50目的普砂、50~70目的普砂以及70~120目的普砂，胶凝材料包括普硅、矿粉、硅灰以及特种水泥，所占的比例分别为普硅22~33%、矿粉5~10%、硅灰3~8%、特种水泥3~10%,颜料为碳黑，外加剂包括聚羧酸高性能减水剂、1~3%羟丙基甲基纤维素、GX‑570偶联剂、消泡剂以及半水石膏。本申请使成品后的水磨石表面更为光滑，内部孔隙率小，使制得的水磨石强度增高、耐久性变强。
