Quick-hardening cementing material as well as preparation method and application thereof
The invention relates to a quick-hardening cementing material and a preparation method and application thereof. The quick-hardening cementing material comprises the following raw materials in parts by mass: 50-100 parts of Portland cement; 10 to 30 parts of fly ash; 3 to 10 parts of silica fume; 5 to 20 parts of sulphoaluminate cement; 0.5 to 2 parts of an accelerator; 0.5 to 3 parts of an inorganic early strength agent; 0.05 to 0.1 part of an alcohol amine early strength agent; 0.5 to 2 parts of calcium formate; and 0.3-2 parts of a water reducing agent. The Portland cement and the sulphoaluminate cement basically do not contain gypsum. In order to control the setting rate within a proper range, the Portland cement without gypsum and the sulphoaluminate cement are matched, and the accelerator, the inorganic-organic early strength agent and the calcium formate are matched, so that the initial setting time can be shortened and relatively high strength can be achieved as soon as possible under the condition that the later strength is not influenced.
一种快速硬化胶凝材料及其制备方法和应用，包括如下质量份数的原料：硅酸盐水泥：50‑100份；粉煤灰：10‑30份；硅灰：3‑10份；硫铝酸盐水泥：5‑20份；速凝剂：0.5‑2份；无机类早强剂：0.5‑3份；醇胺类早强剂：0.05‑0.1份；甲酸钙：0.5‑2份；减水剂：0.3‑2份，所述硅酸盐水泥和硫铝酸盐水泥基本不含石膏。本申请为了将凝结速率控制在适宜的范围之内，采用不含石膏的硅酸盐水泥和硫铝酸盐水泥配合，并且利用速凝剂、无机有机类早强剂以及甲酸钙配合设置，使得可以在不影响后期强度的情况下，降低初凝时间，尽快达到相对高的强度。
