摘要：

This paper describes influence of time and temperature of heat curing on progress of mechanical characteristics of concrete mixtures based on alkali activated fly-ash (POPbeton). One of the major impacts for the correct treatment of alkaline activation is the quantity of heat energy in a given time period which is supplied during activation. The paper describes the dependence of progress of compressive strength of POPbeton on the time and temperature of heat curing. It was assembled a predictive model which describes the dependence of the supplied heat energy over time on the resulting properties of POPbeton. The result is a tool that tray to predict the resulting values of mechanical characteristics of test samples of POPbeton.
