The article discusses the results of experimental studies to identify the effect of chemical additives on the properties of concrete on reducing the water demand and workability of the concrete mixture. The task is the need to increase the operational reliability of concrete and reinforced concrete to the quality of structural building materials, including the most common and resource – intensive-cement concrete. Chemical additives, being one of the simplest and most affordable technological methods for improving the properties of concrete, can significantly reduce the level of costs per unit of production, improve the quality and efficiency of a large range of reinforced concrete elements and structures, increase the service life of both reinforced concrete and reinforced concrete, and buildings and structures. The joint work of chemical additives with the mineralogical composition of cement clinker provides an increase in the strength, density, frost resistance and water resistance of concrete. Only those additives that simultaneously have a plasticizing effect (improving the quality of the concrete mixture), the property of significantly accelerating the end of setting, and are inhibitors of steel corrosion in reinforced concrete elements and structures can provide improvement of these properties. Therefore, great attention is paid to the use of chemical additives in concrete technology in the world practice. The resulting concrete mixture has properties that allow it to be transported over long distances, filled with pumping equipment. The purpose of the work is to obtain a plastic, workable concrete mixture, with the preservation of characteristics over time.
