description: Goal: determination of the optimal amount of mineral additives in modified concretes. Objectives that were solved during the study: 1. To review modified concrete and mineral additives for them, regulatory documents on the use of mineral additives in different operating environments; 2.Â  Conduct tests to determine theÂ  properties of modified concrete with mineral additives; 3. Calculate K-factor for each mineral additive considered in the course of the study, with the aim of their correct use in the composition of modified concretes; 4.Â  Formulate practical recommendations for the standardization of modified concrete with mineral additives in the Russian Federation. The work was fulfilled on the premises ofÂ«MB BetonsgrupaÂ», Liepaja, Latvia, where all the experimental data described in this study were obtained: the values of the initial and final setting time for mixtures with mineral additives (fly ash, microsilikaundensified, microsilika densified, microsilikawhite, metakaolin N, metakaolin I, metakaolin M), values of compressive strength of modified concretes based on mineral additives, values of compressive strength of modified concretes taking into account the K-factor for mineral additives. As a result, all the data obtained during the experiments were analyzed, a table with K-factors was calculated. Recommendations for further research in this area have been developed and an analysis of foreign normative documents in themineral additives in various exposureclasses field has been carried out, which can become the basis for the development of theRussian Federation regulatory documents in this area. Based on the research conducted at Â«MB BetonsgrupaÂ», they started developing a calculator for calculating the amount of CO2 emissions into the atmosphere from concrete production. To achieve these results, Â«MB BetonsgrupaÂ» equipment was used in the work, as well as software (Windows 10, MS Office, Google drive), databases and regulatory documents.
