STUDY OF MOBILITY OF SOLVENT MIXTURE AND THE DURATION OF ITS STIRRING IN THE PREPARATION FOR PERFORMANCE OPUS SIGNINUM PLASTER

Abstract

The paper presents the results of experimental studies to identify dependencies influence the mobility of soluble compounds and duration of mixing mortar mixture during its preparation on physical and mechanical parameters of the proposed opus signinum plaster (creating cracks, porosity, coefficient of water vapor diffusion resistance and compressive strength). as a result, found that the increasing mobility of soluble compounds and duration of stirring during cooking porosity of the plaster and the likelihood of it cracking increases and resistance to water vapor diffusion and compressive strength decrease.
