摘要
采用等温传导量热法、溶解热法和直接法分别测定了不同品种水泥的水化热,并就测试结果进行了对照分析。结果表明,针对不同品种水泥,等温传导量热法与溶解热法测得水泥水化热结果呈现良好的线性关系,与直接法线性关系不佳。就水化放热总量而言,等温传导量热法较其他两种方法测定的结果偏低,并且这一差值随水化龄期的不同而不同。
The heats of hydration of severlkinds of cement have been determined at different test ages in isothermal conduc-tion calorimetry method,solution method and semi-adiabatic method,andtest results have been analyzed accordingly.It showsthatthe heatsof hydrationin isothermal conduction calorimetry methodcan be acted as a good linear functionthose in so-lution methodwith different kinds of cement.On theother hand,the testresultsare presented aspoor linearfunctionbetween in isothermal conduction calorimetry methodand semi-adiabatic method.In terms of total heatsof hydration,that measuredby-isothermal conduction calorimetryis lower than bytheothertwoways.In addtion,the difference varies along with hydration ages.
