Experimental studies were conducted on the selection of rocks whose properties would satisfy the requirements for decorative concrete blocks made from them. Such properties as decorative effect, compressive strength, water absorption, abrasion resistance, impact resistance, frost resistance, etc. were evaluated. The properties of fine aggregate were also evaluated, from carbonate rocks — sand. Based on the work carried out, proposals were developed for a rational selection of the composition of decorative concrete

Keywords: decorative features, abrasivity, marbled limestone, frost resistance, aggregates
