Composite early strength agent for cement material in low-temperature environment, and application thereof
The invention discloses a composite early strength agent for a cement material in a low-temperature environment, and application thereof. The composite early strength agent is composed of soluble meta-aluminate, soluble calcium salt, an alcohol amine substance and a water reducing agent, the addition amount of the soluble meta-aluminate is 0.15-0.25% of the mass of a cementing material, the addition amount of the soluble inorganic calcium salt is 0.80-2.00% of the mass of the cementing material, the addition amount of the alcohol amine substance is 0.02-0.05% of the mass of the cementing material, and the addition amount of the water reducing agent is 0.30-0.50% of the mass of the cementing material. The composite early strength agent accelerates the cement hydration reaction process, the cement hydration reaction process and the cement hydration reaction process show a progressive enhancement effect, the early strength of the concrete is greatly enhanced due to the synergistic use of the water reducing agent, and while the problem of slow development of the early strength of the concrete in a low-temperature environment is solved, the early mechanical property of the concrete is obviously improved at lower production cost, so that the concrete meets the requirements of the building material field on the concrete under the construction condition in winter, and the defects of the existing early strength agent are overcome.
本发明公开了一种用于低温环境下水泥材料的复合型早强剂及其应用，所述复合型早强剂由可溶性偏铝酸盐、可溶性钙盐、醇胺物质和减水剂组成，可溶性偏铝酸盐的添加量为胶凝材料质量的0.15－0.25％，可溶性无机钙盐的添加量为胶凝材料质量的0.80－2.00％，醇胺物质的添加量为胶凝材料质量的0.02－0.05％，减水剂的添加量为胶凝材料质量的0.30－0.50％。本发明的复合型早强剂加速了水泥水化反应进程，彼此之间表现出递进增强效果，同时协同减水剂的使用，大大增强了混凝土的早期强度，在解决混凝土在低温环境下早期强度发展缓慢问题的同时，以较低的生产成本明显提高了混凝土的早期力学性能，使其满足冬季施工条件下建材领域对混凝土的要求，克服现有早强剂所存在的不足。
