Research of Mechanochemical Processes of Activation of Building Materials by Air-Impact Method

To increase the specific surface area of binder and accelerate strength gain fast-hardening concrete mixtures, a model has been created for calculating aeroactivators as part mobile complexes based on new equipment cement activation, sand enrichment, local materials, production waste. The proposed establishes dependence rate destruction dusty shell particles mechanical impact beaters materials` physical characteristics. improve operational characteristics aeroactivator, experimental studies were carried out, results which made it possible to determine rational parameters developed installation. Based test results, was found that use activation process with additives accelerates hardening mortar mixtures in initial period, increases design concretes mortars by 20–40% comparison control composition at same consumption, also reduces consumption up 17% obtain equal age.
