The main characteristic of hydrotechnical cement, which is used to build massive structures, is the low heat of hydration. In this work is examined the effect of the electrofilter ash with a high content of calcium oxide addition on the hydration heat of Portland cement. The cement samples containing 0% to 50 % fly ash from TPP „Kakanj“...
