the dimension of the massive concrete is very huge. after the concrete is poured, a great deal of hydration heat of cement is given off. so the deleterious crack comes into being.
大体积混凝土体积庞大,混凝土浇筑后释放大量水化热,导致混凝土结构产生有害裂缝。
during concrete winter construction, the hydration heat of cement can be made use of as a sort of energy.
在冬季混凝土施工中,水泥的水化热是一项可以利用的能源。
a new formula was proposed to simulate the hydration heat of cement in concrete. the model takes the influence of temperature and concentration of reactant into account .
提出了考虑温度和化学反应物浓度影响的混凝土水泥水化反应放热模型。
the hydration heat of cement paste was tested to investigate the influence of sulfate content in cement paste on the compatibility of cement and naphthalene superplasticizer.
同时测定水泥浆体的水化放热,确定水泥浆体中硫酸盐含量对水泥和萘系减水剂相容性的影响。
