The reduction of energy consumption in manufacturing concrete and reinforced concrete structures is a topical and important problem that can be solved by using hardening accelerators. The conducted research shows high technical effectiveness of the application of galvanic sludge and super plasticizers in concrete manufacture. The application of the developed complex ad mixture enables increasing the concrete strength by 50-60% in the first 24 hours of hardening. The effectiveness of the application of this admixture depends on coarseness of the sand used in concrete manufacture.

Abstract


The reduction of energy consumption in manufacturing concrete and reinforced concrete structures is a topical and important problem that can be solved by using hardening accelerators. The conducted research shows high technical effectiveness of the application of galvanic sludge and super plasticizers in concrete manufacture. The application of the developed complex ad mixture enables increasing the concrete strength by 50-60% in the first 24 hours of hardening. The effectiveness of the application of this admixture depends on coarseness of the sand used in concrete manufacture.
