The development of theoretical and experimental research in the field of quality
control has led to the development of many methods for assessing the strength of
concrete. The temperature-strength control (TSCC) method, which is based on the
relationship between concrete temperature and curing time, is the most adapted method
for quickly determining the strength of the concrete in the formwork during the early
phase of curing. The concrete strength tests must be carried out in accordance with the
requirements of the standards. The most adapted standards are ASTM C1074 (USA);
NEN 5970 (Netherlands); ST-NP SRO SSK-04-2013 (Russia). However, there are no
existing approaches to TSCC that consider all the advantages of each method. Using the
method of paired comparison, the authors determined the weights of the significance of
each criterion of methods and tasks for TSCC. Based on of the obtained results a unified
approach to temperature-strength control of concrete has been formed considering the
assessment of its applicability. This approach will solve the problem of limitation of the
application of most methods, which in its basis have the best methods in solving tasks of
control stages. The unified approach to temperature-strength control of concrete will
allow to achieving high quality and durability of concrete and reinforced concrete
structures.
