3D printing concrete cement and preparation method thereof
The invention relates to 3D printing concrete cement and a preparation method thereof, the 3D printing concrete cement is fast in setting time, high in strength and not easy to crack, and the 3D printing concrete cement comprises the following components in parts by weight: 60-65 parts of fluoroaluminate cement clinker, 30-35 parts of steel slag, 10-15 parts of calcium nitrate, 10-15 parts of alkali lignin, 10-15 parts of a cement thixotropic lubricant and 10-15 parts of a micro-expansion agent. The cement-based composite material comprises the following components in parts by weight: 3-5 parts of calcium nitrate, 3-5 parts of alkali lignin, 0.05-0.2 part of a cement thixotropic lubricant and 0.03-0.1 part of a micro-expanding agent, the preparation method comprises the following steps: crushing the fluoroaluminate cement clinker and the steel slag to obtain mixed powder, adding the calcium nitrate, the alkali lignin, the cement thixotropic lubricant and the micro-expanding agent, and grinding by using an open-circuit ball mill.
一种3D打印混凝土水泥及其制备方法，3D打印混凝土水泥凝结时间快、强度高且不易开裂，包括氟铝酸盐水泥熟料、钢渣、硝酸钙、碱木素、水泥触变润滑剂和微膨胀剂，其中氟铝酸盐水泥熟料的重量组分为60‑65份，钢渣的重量组分为30‑35份，硝酸钙的重量组分为3‑5份，碱木素的重量组分为3‑5份，水泥触变润滑剂的重量组分为0.05‑0.2份，微膨胀剂的重量组分为0.03‑0.1份；制备时先将氟铝酸盐水泥熟料和钢渣一起粉碎得到混合粉末，再将硝酸钙、碱木素、水泥触变润滑剂和微膨胀剂加入，使用开路球磨机粉磨。
