NORMATIVE REGULATION OF METHODS OF TEMPERATURE AND STRENGTH CONTROL OF CONCRETE

The maturity method is an approach to concrete quality control that predicts the in-situ strength based on internal temperature. It is known that the cement hydration process takes place during the hardening of concrete. This process causes the cement to become waterlogged, due to which energy is released. Temperature and moisture are then the main characteristics to control the strength of concrete. The degree of maturity depends on the changing curing conditions by measuring and recording the internal temperature of the concrete using special sensors and registers embedded in the concrete at the time of placement. This approach is now widely used all over the world. There are, however, other methods of calculation regulated in the standards of other countries. The following article is devoted to the analysis of existing methods of temperature and strength control of concrete. A list of normative documents regulating these requirements is given in the article, the features, advantages and disadvantages are discussed. Also the authors justify the necessity of formation of the unified approach to temperature-strength control of concrete.
