  • We study on the segregation reduction effect of Self-Leveling Color Mortar by using variable composition set of plasticizer and thickener, Naphthalene, melamine and polycarbonate-based dispersants were employed as plasticizers for examining on fluidity of mortar mixtures. For enhancement of mortar stability without loss of it's fluidity, two types of thickener were used such as polysaccharide(PS) and hydroxyethylcellulose(HEC). As a result, the most effective mortar was composed by feeding 0.519% of polycarbonate-based dispersant with 0.002587% of PS and 0.155844% of HEC on amount of basic mortar.

  • The purpose of this study is to develop a floor mortar construction technique which has high strength and inherent mechanical properties and does not cause cracks due to shrinkage after construction. It has been demonstrated that compressive strength, bending strength, flow with floor mortar, and crack reduction performance. As a result, it was confirmed that the developed floor mortar had the same or better performance comparing with the existing foreign products. The results of this experiment can be used as a validation material for high performance and high flowable mortar construction technology with excellent material performance, economical efficiency and construction ability by securing the required performance as floor mortar and selecting the optimal formulation.

  • This study is about high strength self-leveling mortar according to the mixing ratio of polymer. The self-leveling mortar currently released in Korea maintains a compressive strength of 40 Mpa as of 28 days. In addition, the level of bonding strength and flexural strength are kept the same. However, through this study, it is confirmed how the self-leveling mortar with a compressive strength of 60Mpa as of the 28th is shown according to the amount of polymer mixed. Experimental factors were configured according to the amount of polymer mixed, and the types of experiments were to confirm compressive strength, flexural strength, adhesion strength and flow. In addition, by confirming the early strength, a study was conducted to improve the quick workability compared to the self-horizontal mortar in the market.
