This article presents the results of experimental studies of cement binder from local raw material bases optimal for the production of cast modified concrete (CMC). Having a special self-compacting nature, as well as a sensitive cost-effectiveness for the Kazakhstan concrete mixtures manufacturer, this type of concrete requires the use of cement with stable physical and technical characteristics. The study conducted an analysis of the nomenclature of local bases of cement raw materials, testing for cement fineness of Portland cement PC 400 D20 and compressive strength. It is revealed that in Kazakhstan there is a fairly wide range of cement products available with and without additives, produced by dry and wet method. Samples of Portland cement with mineral additives were taken for testing. According to the results of tests, the best indicators of grinding fineness 94.65% and compressive strength on 28 days 42.8 MPa were obtained for Portland cement with mineral additives of Bukhtarminskaya cement company LLP, produced by wet method.
