МЕТОДИКА КОНТРОЛЯ КАЧЕСТВА УСТРОЙСТВА ПОЛОВВ УЧЕБНЫХ ЗАВЕДЕНИЯХ

A quality control method for in-use floors is proposed, based on a comprehensive application of physical and chemical analysis methods and non-destructive testing techniques.A comprehensive analysis revealed that a semi-dry cement-sand screed fails to achieve its design characteristics due to an insufficient amount of Portland cement in the mixture.The high water-to-binder ratio during self-leveling floor installation is due to the high calcite content in its composition; as a result of use, the floor peels off from the screed due to poor adhesion.Insufficient hydration has been observed in polymercement self-leveling floors when the mixture is over-wetted during installation.The proposed quality control methods, both during floor installation and after use, can improve the quality of construction and installation work during floor installation and provide more comprehensive information when analyzing the causes of defects and damage.
