摘要
水泥水化放热使得大体积混凝土内部温度会急剧升高,由于大体积混凝土厚度大,水化热消散越慢,造成大体积混凝土内部温度过髙,混凝土内外温差大,引起大体积混凝土裂缝。通过在混凝土中分别加入抑制剂和氧化镁,现场试验分析添加剂对大体积混凝土内部温度变化的影响。
Cement hydration exothermic makes the internal temperature of mass concrete rise sharply.The thicker mass concrete is,the slower the hydration heat dissipates.The excessive internal temperature of mass concrete results in large temperature difference between inside and outside of the concrete,causing cracks in mass concrete.In this paper,inhibitors and MgO are added to concrete respectively,and the effect of additives on the internal temperature change of mass concrete is analyzed through field tests.
