Abstract:
A computer controlled temperature matched curing system to simulate curing of concrete in structures is presented. The system has capability to accurately control the ambient temperature against the hydration temperature generated by a fully insulated concrete specimen. It is also capable of simulating any cooling rate which might occur on site and which depends on the thickness of the concrete element, the type of formwork, the ambient temperature, humidity and wind velocity. Data of normal portland cement concrete and fly ash concrete of different compositions cured at 5°C and 20°C and 35°C are compared with data of concrete cured using semiadiabatic conditions and the effect of simulating the cooling-time curve is discussed on the light of the results of strength porosity and permeability.
