Abstract

In the modern technology of concrete production, additional modifiers are a mandatory component of the concrete mixture along with binders, fillers and water. Additives in concrete are used to improve the quality of concrete, give it its own characteristics, speed up construction work, and reduce the cost of the construction process. Currently, due to the increasing requirements for concrete used in construction objects, in order to use admixed concrete more, as a result of scientific research, the cheapest, high-quality, effective results were obtained and recommended for production.
