Influence of Ash and Slag Wastes of Thermal Power Plants (TPP) and Conditions of Hardening on Portland Cement Activity
Abstract: The results of a comparative study of the activity of Portland cement on the content of additives of ash-entrainment and ground slag TPP have been given. It was found out that the dependences of strength of Portland cement stone on the content of additives are commensurate, but the strength of samples with ash is consistently higher. Increasing the hardening time under normal conditions, the use of steaming and, especially, autoclaving allows to maintain the activity of mixed binders at the level of pure Portland cement or lose it within less than 20…40 % with a higher content of additives.
Keywords: Portland cement, fly ash and slag of thermal power stations, conditions of hardening, strength.
