Complex Organomineral Additives with Hardening Accelerator

摘要

A complex organomineral additive based on local raw materials (diatomite), superplasticizer and accelerator for sodium sulfate hardening has been developed. The possibility of using activated diatomite in the composition of concrete instead of microsilica with activation of the sodium sulfate hardening process is shown. The results of the effect of additives on the composition of the hydrated phases of cement systems, the processes of structure formation and hardening of cement materials, the effect of a complex additive on the strength of concrete are given. The achievement of high strength parameters of concretes, including those with a lower cement consumption, is ensured by introducing into the concrete mix fine-dispersed mineral components that promote the creation of a Theologically active matrix and increase the effectiveness of super-and hyperplasticizers.
