A unified approach for temperature and strength control of concrete

Abstract

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.
