Assessing the Level of Concrete Hardening by the Maturity Method

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.
