Abstract
Abstract Curing levels under standardized temperature and humidity conditions of concrete (but also for medium temperature conditions in the range of +5 o C → +35 o C, maximum +40 o C, depending on the type of cement used in the preparation of concrete, in order not to record final resistance losses) can be plotted graphically with a single chart for all concrete grades prepared with the same type of cement at different ages. Each concrete hardening diagram corresponds to a degree of maturation, defined as the area between the average temperature plot of the concrete and the -10 ° C order, over time, so that only resistance based on the temperature measurement during the curing can be evaluated (or the level of hardening) of the concrete necessary for the technological process - decofing, precompression force transfer, acceptance of freezing of the concrete without adverse effects, precast concrete transport etc., but also the necessary times for starting a technological process.
