Early strength agent for pavement concrete
The invention relates to an early strength agent for pavement concrete. Reference cement of concrete is taken as a substrate. The early strength agent is prepared from the following raw materials in parts by weight: 1.5 to 2.5 parts of sodium sulfate, 1.6 to 2.5 parts of gypsum, 0.01 to 0.07 part of triethanolamine and 0.8 to 1.3 parts of sodium chloride. Organic matters and inorganic salts are compounded to form the early strength agent; four components: sodium sulfate, gypsum, triethanolamine and sodium chloride are compounded and used, the compressive strength of the obtained precast concrete at each age is higher than that of concrete that does not contain the early strength agent, the early cement strength can be enhanced, the later strength is not influenced, and the cement setting time, stability and fluidity are not influenced.
本发明涉及一种用于路面混凝土的早强剂,以混凝土的基准水泥为基底,包括如下重量份的原料:硫酸钠1.5‑2.5份,石膏1.6‑2.5份,三乙醇胺0.01‑0.07份,氯化钠0.8‑1.3份;本发明采用有机物类与无机盐类复合形成,通过硫酸钠、石膏、三乙醇胺和氯化钠四元复合使用,所得到的预制混凝土的各个龄期的抗压强度均比不加入早强剂的混凝土的抵压强度高,可以增强早期水泥强度,对后期强度没有影响,对水泥凝结时间、安定性、流动度不产生影响。
