Title of the articleUse the fine screenings of concrete waste in a cement composition for producing mortar
Abstract.The involvement of concrete waste in construction is one of the promising areas of recycling this waste while reducing the consumption of natural mineral resources. The aim of this work was to study the effects of the introduction of fine screening concrete waste to replace a portion of Portland cement in the binder for construction materials, in particular mortar, on primary physical-mechanical properties of solutions. The result of the executed researches is to establish the possibility of obtaining a mortar with replacement of up to 15 % of Portland cement in the binder for fine screening of concrete waste without significant reduction in strength characteristics of the solution and not inferior to the performance properties of industrial analogues. Maintaining the strength of the artificial stone with the introduction of additives fine screening of concrete waste in the composition of the binder when replacing part of Portland cement is a manifestation of the effect of steric constraint and hardening process not previously hydrated particles of Portland cement clinker in the additive.
Keywords.screening of concrete waste, mortar, portland cement, dry mortar, artificial stone, calorimetry.
