ON THE PROPERTIES OF CEMENT-SAND MORTARS PLASTIFIED WITH CARBONATE CLAYS

Abstract

The use of cement-sand mortars plasticized with carbonate clays in earthquake-resistant construction has been demonstrated in experimental tests. The compositions and physical-and-mechanical characteristics of these mortars have been identified for the first time, allowing for a reduction in cement consumption of up to 40% as well as a complete elimination of the costly lime while enhancing the mortar's strength. The use of cement-sand mortars plasticized with carbonate clays has been suggested for performing earthquake-resistant construction from local sawn limestone. The experiments’ findings were put to the test and put into practice in Nagorno-Karabakh's construction complex. The study's finding s are in line with research and regulatory documents for cement-clay mortars for masonry.
