| Title of the article | An additive-accelerant for concrete hardening on the base of industrial waste |
| Abstract. | Research has been carried out on the study of mineralized flow effectiveness – waste of metallurgy as an accelerant additive for concrete hardening. It has been found out that these flows intensify the process of cement hydration and a set of concrete durability especially in initial period. In the presence of flows the microstructure of the cement stone is modified as for the increase in its density. To prevent the reinforcement corrosion development in the presence of the salt flaws a complex accelerant is suggested including a corrosion inhibitor in addition to the flows. The products phase composition of the new formation of cement stone with the complex accelerant changes with an emergence of additional products of hydration – hydrochlorinealuminates and calcium hydronitroaluminates, which lead to an additional increase in durability and density of the cement stone and concrete. The use of the accelerant broadens the nomenclature of non-deficit available chemical accelerants and provides: an increase in concrete durability without excessive consumption of binding materials; reduction in cement consumption for obtaining full strength concrete; an increase in the set of concrete durability in initial periods. The use of mineralized (salt) flows in concrete technology allows to improve ecological safety at the expense of industrial waste emission reduction into the surrounding environment. |
