Abstract. The influence of additives bebida on structure of bentoniteВ­cement composite solutions, based on the results of the study found that the use of additives in the form of vysokohromistyh waste aluminothermic production of chromium in the number 0,208% by weight of cement allows to obtain composite materials characterized by increased strength. A study of the toxicity of building composite systems with additive bemid, as well as the individual components on biological activity environments on a plantВ­based Biotest systems. Proven environmental safety of the modified composite that allows recommend it for improvement of safety at construction and repair.

Key words: composite materials, bentoniteВ­cement composite solutions, kinetics, structure formation, strength, phytotoxicity, toxicity, and environmental safety.
