Obvious advantages of industrial, in the first place, large-panel housing construction make it an important and highly competitive sector in the construction of social housing in large cities. The development of the technology of large-panel housing construction predetermines the need of improving the technology of concretes providing the manufacture of products with high-quality surfaces at minimal cost for molding, steam treatment, finishing products, acceleration of molds reusing, reducing the cost of concrete mix and product, reducing the human factor influence on the production process as a whole that predetermines the need to widely use additives, complex including, for solving technological problems in the field of the technology of concretes for large-panel construction. National manufacturers of additives and foreign companies, which have organized their enterprises on the territory of the Russian Federation, are able to meet the need of enterprises of large-panel housing construction for all necessary additives. Additives to concrete are the most powerful instrument for regulating the properties of concrete mixes; they greatly influence on the whole technological cycle. A key point is providing the stability of the technological process, i.e. guaranteed results at possible fluctuations of technological parameters in a fairly wide range. Keeping this in mind, the assessment of technical-economic efficiency of the use of additives at largepanel prefabrication plants should be made.
