| Title of the article | The phase composition of the hydrated cement hardening accelerator complex |
| Abstract. | Energy savings in the production of concrete products and structures was and is one of the most important tasks of concrete technology. In the manufacture of concrete products is the most energy-intensive process of heat and humidity treatment, passing at temperatures 40-90 0C. This method is faster curing of concrete used in most enterprises of precast concrete. The very process of such processing products poorly to adjust even with modern methods of automation and accompanied by large heat losses to the environment. One way to improve the economic efficiency of the use of chemical additives is to use in their production of industrial wastes and by-products. The use of waste can also solve the environmental problem of waste in the workplace. One of the technological waste is galvanic sludge generated by the processing of aluminum products. Sludge is a concentrated aqueous dispersion of aluminate is undoubtedly of interest to use as an additive in cement concrete, but not in pure form and in combination with other functional components. Introduction of integrated accelerator based electroplating sludge in cement systems leads to accelerate the formation of crystal structure in the early stages of hardening and speed dial concrete strength. Acceleration of hardening cement paste with galvanic sludge due to the formation of ettringite. Since the maximum content of aluminum sulfate in GS-1, and it has the greatest contribution to his education. |
