Laboratory tests were conducted of mortars supplemented with 0%, 5%, 20%, 35%, 50% of chalcedonite powder. Chalcedonite powder replaced the percentage amount of cement. The subject of tests was impact of admixture on properties of hardened mortars including: compressive strength, bending strength, water absorption and capillary rising. Tests of com...
