Abstract
The purpose of this study is to develop a single coat plaster finishing dry cement mortar (DM) for improving the workability and quality of DM for flooring. An effective admixture selection and mixing rate were determined to ensure high fluidity and material separation resistance, and the physical properties of DM for single coat plaster finished floors using it were reviewed. As a result of this experiment, the type and mixing rate of an appropriate plasticizer and viscosity enhancing agent having both high fluidity and material separation resistance were determined. A DM for single coat plaster finished floors premixed with this was developed. The developed DM for floors had high fluidity, which made it possible to improve workability, simplify the plastering process, and secure stable material separation resistance according to the fluctuation of the mixing quantity on site. It was verified that the compressive strength exceeded the quality standards of KS, and the length change rate was effective in reducing cracks due to the reduction in drying shrinkage caused by the reduction in W/DM.
