(Received December 9, 2013)(Revised December 23, 2013)(Accepted January 10, 2014)Abstract This study analyzed the fundamental characteristics of concrete according to a ternary system mixing in order toreduce hydration heat of mass concrete and to improve early age strength. The results are as follows. The fluidity ofunconsolidated concrete satisfied the target scope regardless of the binder conditions. When the replacement ratio betweenFA and BS increased, the slump of low heat-A mix and low heat-B mix increased, and air content was not affected by thechange of binders. As for setting time, low heat cement mix had the fastest regardless of W/B, and high early strengthlow heat mix achieved 6 hours’ reduction compared with low heat-B mix at initial set, and 12 hours’ reduction at the finalset respectively. As for the simple hydration heat, the low mix peak temperature was the highest and low heat-B mix hadthe lowest temperature. And high early strength low heat mix was similar with that of low heat-B. The compressivestrength of hardened concrete had similar strength scope in all mixes except for low heat-B mix at early ages, and hadunexceptionally similar one without huge differences at long-term ages.Key wordsEarly age strength, Low heat cement, Heat of hydration, Mass concrete
