자기수평 모르타르의 재료분리저감을 위한 고성능 유동화제와 증점제의 최적 조성비에 관한 실험적 연구

다국어 초록 (Multilingual Abstract)

Superplaticizers and thickners are additives used to control the balance between the fluidity and the stability of self-leveling mortars. This experimental study is intended to find out the optimal ratio of these two additives which minimizes the segregation of the self-leveling mortar during its application, while maintaining the sufficient level of fluidity at the same time. Naphthalene, melamine and polycarbonate-based superplasticizers were tested along with the following choice of thickners: Polysaccharide (PS) and hydroxyethylcellulose (HEC). As a result, the most effective composition of self-leveling mortar turned out to be 0.519% polycarbonate-based superplaticizer with 0.002587% of PS and 0.155844% of HEC in the ratio by the weight of the inorganic binders. This composition not only enhanced the mortar stability without loss of its high-fluidity, but was able to prevent the segregation of material completely.
