STUDY ON COLD WEATHER CONCRETING USING LOW-HEAT CEMENT

In this paper, properties of frost damage at early age and strength development and thermal crack were studied, for purposes of application to the mass concrete of low-heat cement in cold weather, by means of concrete experiments and temperature analysis by finite element method. The experiments and the analysis result showed that the strength for resistance to frost damage at early age was 5N/mm^2, the concrete strength correction value in terms of curing temperature was calculated approximately, and was effective in the resistance of thermal crack. And then, the application ranges of construction procedures were investigated.
