Title of the articleInfluence of complex hardening accelerator for heat treatment of fine-grained concrete
Abstract.Reduction of setting time of cement and intensify its hardening relevant for normal concrete curing and humidity, and exposed to heat and humidity treatment. Supplementation accelerator setting and hardening, hardening accelerators integrated into the concrete activate the processes of cement hydration. As additives, accelerators can be utilized effectively various waste products, for example, electroplating sludge containing sulphates and incorporates alumina. The authors developed an integrated accelerator representing water-insoluble particulate material consisting of a superplasticizer C-3 of the dried slurry electroplating. When the normally humid storage increase the compressive strength of concrete additive developed by 60 % relative to composition no addition. An integrated hardening accelerator reduces cooking time up to 9 hours or reduce the temperature to 400C . Introduction of integrated accelerator based electroplating sludge in cement systems leads to faster crystallization structure formation in the early stages of hardening and accelerated set of concrete strength, which can significantly reduce energy consumption in the production of concrete products by reducing heat and humidity treatment time or temperature.
Keywords.A hardening accelerator, a fine-grained concrete galvanic sludge strength of heat treatment.
