Early-strength low-shrinkage cementing material and preparation method thereof
The invention discloses an early-strength low-shrinkage cementing material and a preparation method thereof.The preparation method comprises the following steps that firstly, mixed raw materials containing silicon, aluminum, sulfur, calcium and iron are ground and homogenized and then subjected to high-temperature calcination, the high-temperature calcination temperature is 1250 DEG C +/-100 DEG C, and early-strength low-shrinkage clinker is prepared; mixing the clinker, the cementing material mixed material and gypsum, and grinding the mixture into powder with the specific surface area of 200m < 2 >/g-800m < 2 >/g, so as to obtain the early-strength low-shrinkage cementing material. Or the raw materials are respectively ground into powder with the specific surface area of 200m < 2 >/g-1000m < 2 >/g, and then the powder is mixed to obtain the early-strength low-shrinkage cementing material. The calcium sulfate is adopted to activate the dicalcium silicate, the final activity of the dicalcium silicate is guaranteed, and the mechanical property of the cement-based material can be optimized by regulating and controlling the content of the dicalcium silicate and the anhydrous calcium sulphoaluminate.
本发明公开了一种早强低收缩胶凝材料及其制备方法，包括如下步骤：首先将含有硅、铝、硫、钙和铁元素的混合原料粉磨、均化处理后，再经高温煅烧，高温煅烧的温度为1250℃±100℃，制备得到所述的早强低收缩熟料；再将熟料、胶凝材料混合材和石膏，混合后共同粉磨至比表面积为200m2/g～800m2/g的粉体，得到早强低收缩胶凝材料；或将各原料分别粉磨至比表面积为200m2/g～1000m2/g的粉体，然后再混合得到早强低收缩胶凝材料。本发明采用硫酸钙活化硅酸二钙，保障了硅酸二钙的最终活性，并且通过调控硅酸二钙和无水硫铝酸钙的含量，可以优化水泥基材料的力学性能。
