EFFECT OF ACTIVATION OF BINDER MINERAL ADMIXTURES ON CONCRETE MIX STRENGTH

Development prospects of mineral mining and processing in technologically advanced countries are connected with wasteless and low-waste technologies of mineral extraction and waste management. Mining development efficiency is supported by scientific research into mineral structure and response as well as into the type of action aimed to alter the properties of waste and compounds of minerals of similar chemical compositions. Structural responsiveness of minerals can be changed using different methods, including the most critical mechanochemical approaches. Mechanochemical effects generate particles having different type defects and energy levels of surface. Structural transformations in surface layers of a mineral subjected to activation improve the contrast and gradient of properties, which allows commodity production from junk based on disintegration technology. Efficient subsoil management uses technologies with cemented backfill, which needs that mining provides raw material for preparation of cemented mixes. Deficiency of binders can be overcome by using binding mineral admixtures made of waste, including plastifiers among other things. Properties of binders and aggregates in a cemented mix can be adjusted by mechanical action, for instance, in disintegrators making use of inertia forces of materials at high rotation speeds. Majority of waste both in mining and in allied industries can be components of cemented mixes, which is determined by tests of compounding properties under specific conditions.
