The high level of unfair competition in the concrete market and the dumping price for concrete mixtures, dictated by consumers, are the reason for the appearance of falsified concrete mixtures in the market. In order to increase the margin of the business, many concrete manufacturers supply mixtures to the construction site that do not meet the characteristics, specified in the mixture passport. The statistics of state construction supervision bodies according to the results of non-destructive testing of finished concrete structures at construction sites from year to year shows a steady decrease in the strength characteristics of concrete structures, which negatively affects the safety of construction. For this reason, the problems of eliminating the falsification of concrete products and ensuring the safety of construction sites, constructed with concrete, remain very relevant.
One of the ways to solve this problem was the inclusion in the Decree of the Government of the Russian Federation No. 982 dated 01.12.2009 “On approval of a single list of products, subject to mandatory certification, and a single list of products, the confirmation of which is carried out in the form of a declaration of conformity” standards for concrete mixtures (GOST 7473-2010 “Concrete mixtures. Technical Specifications”) and for construction solutions (GOST 28013-98 “Construction solutions. General Technical Specifications”), that is, mixtures, prepared on concrete-mortar units. This amendment was introduced on December 27, 2018 by Decree of the Government of the Russian Federation No. 717 dated 17.06.2017, according to which the concrete mixtures and mortars, as well as dry mixtures, are included in the list of products, subject to mandatory confirmation of conformity in the form of a declaration of conformity. In addition, there is currently developed and approved GOST R 58763-2019 “Conformity assessment. Rules for declaring the conformity of mixtures and mortars”, which will enter into force on January 1, 2021. It determines the procedure for the declaration of conformity of mixtures and mortars of construction, including concrete.
