摘要
为了探讨低热硅酸盐水泥对大坝混凝土体积稳定性的影响,采用SL352—2006《水工混凝土试验规程》规定的试验方法,研究了低热硅酸盐水泥对大坝混凝土体积稳定性的影响。试验结果表明:低热硅酸盐水泥大坝混凝土具有温度变形、收缩变形和碱骨料反应活性膨胀变形较小的特点,与中热硅酸盐水泥相比,低热硅酸盐水泥可以提高大坝混凝土的体积稳定性。
In order to investigate the effect of low heat Portland cement on concrete dam volume stability, we applied the test method according to the Hydraulic Concrete Testing Procedures （ SL 352-2006 ） regulations. Overall, the experimental studies show： low heat Portland cement concrete has characteristics of low temperature deformation, low shrinkage and reducing swelling alkali reactivity. Further, compared with moderate heat Portland cement, low heat Portland cement concrete can increase the volume stability of dam.
