Quick-setting early-strength inorganic material as well as preparation method and application thereof
The invention provides a quick-setting early-strength inorganic material as well as a preparation method and application thereof. The inorganic material mainly comprises the following raw material components in parts by weight: 10-60 parts of aluminate cement, 15-50 parts of high-calcium minerals, 15-40 parts of gasified slag, 10-35 parts of bauxite slag and 0.06-0.5 part of a retarder. Wherein the content of free calcium oxide in the high-calcium minerals is 2%-40%, the retarder is organic acid containing carboxylate radicals, and the weight ratio of the aluminate cement to the high-calcium minerals is 1: (0.5-4). The preparation method comprises the following steps: mixing aluminate cement, high-calcium minerals, gasified slag, bauxite slag, a retarder and a plasticizer to obtain a solid master batch; and mixing the solid master batch with water according to a liquid-solid ratio of 0.1-0.8, and uniformly stirring to prepare the quick-setting early-strength inorganic material. By controlling the adding proportion of the high-calcium minerals, the aluminate cement and the retarder, the setting time of the cementing material is shortened, and the cementing material has high early strength.
本发明提供了一种快凝早强型的无机材料及其制备方法和应用，无机材料主要包括以下重量份的原料组分：铝酸盐水泥10～60重量份，高钙矿物15～50重量份，气化渣15～40重量份，铝土矿渣10～35重量份，缓凝剂0.06～0.5重量份；其中，高钙矿物中游离氧化钙的含量为2％～40％，缓凝剂为含有羧酸根的有机酸，铝酸盐水泥与高钙矿物的重量比为1:(0.5～4)。本发明的制备方法包括：将铝酸盐水泥、高钙矿物、气化渣、铝土矿渣、缓凝剂和增塑剂混合得到固体母料；将固体母料与水混合，液固比为0.1～0.8，搅拌均匀制成快凝早强型的无机材料。本发明通过控制高钙矿物、铝酸盐水泥与缓凝剂的添加比例，缩短了胶凝材料的凝结时间，具有较高的早期强度。
