Composite cementing material for exciting hydration of C3S
The invention discloses a composite cementing material for exciting hydration of C3S, which relates to the field of building materials, and provides a cement-based composite cementing material rapid in hydration hardening and excellent in early strength. The composite cementing material is prepared from the following raw materials in percentage by mass: 90% of C3S single ore, 3%-8% of high-temperature gypsum and 2%-7% of anhydrous calcium sulphoaluminate. Through synergistic hydration reaction of anhydrous calcium sulphoaluminate, high-temperature gypsum and C3S, hydration of C3S is accelerated, ettringite and a gel phase are rapidly formed, and the structure is compact, so that relatively high strength is achieved in early hydration of cement.
一种激发C3S水化的复合胶凝材料涉及建筑材料领域，提供水化硬化快，早期强度优异的水泥基复合胶凝材料。该复合胶凝材料包括以下质量分数配制的原料：C3S单矿90％，高温石膏3％～8％，无水硫铝酸钙2％～7％。本发明通过无水硫铝酸钙、高温石膏、C3S的协同水化反应，加快C3S的水化，快速形成钙矾石和凝胶相并使得结构致密，从而在水泥的早期水化中达到较高的强度。
