Abstract
In modern construction concrete recycling is one of the promising directions of utilization of multi-tonnage concrete and reinforced concrete waste. Most often concrete crushing products are reused as coarse and fine aggregate. It is shown in the paper that reuse of the dusty fraction of cement-sand stone as an active colloidal additive obtained by its alkaline mechanical-chemical activation allows to partially replace cement in commercial concrete and hydraulically hardening compositions without loss of their strength. This paper presents the results of the effect of colloidal admixture on technological and physical-mechanical properties of concrete mixture.
