Plastering omitable wet self-filling mortar composition for flooring
The present invention relates to a wet self-filling mortar composition for floor plastering which improves performance such as fluidity and a shrinkage reduction effect and allows surface finishing only by leveling without a plastering process. The present invention provides the wet self-filling mortar composition for floor plastering which is a mortar composition with a design standard strength of 21 MPa or more containing a binder, a fine aggregate, a mixing water, a water reducing agent, and a shrinkage reducing agent, and has a binder amount of 500-600 kg/㎥, a fine aggregate amount of 1,150-1,350 kg/㎥, and a water-binder ratio of 50-60 wt%. By controlling a surface tension of a mixture of the mixing water, the water reducing agent, and the shrinkage reducing agent at 20℃, a drying shrinkage at 28 days is less than 600 με, and a mortar flow standard of 250 ± 30 mm is met.
본 발명은 유동성, 수축저감 효과 등의 성능을 개선시켜 미장공정을 생략하고 고름질만으로 표면 마감을 할 수 있는 방통용 습식 자기충전 모르타르 조성물에 관한 것이다. 본 발명은 「결합재, 잔골재, 배합수, 감수제 및 수축저감제를 포함하는 설계기준강도 21 MPa 이상인 모르타르 조성물로서, 결합재량 500~600 kg/㎥; 잔골재량1,150~1,350 kg/㎥; 물-결합재비 50~60 wt%; 이고, 상기 배합수, 감수제 및 수축저감제 혼합액의 20℃ 조건 표면장력을 통제하여, 재령 28일 건조수축량이 600 με 이하가 되고, 모르타르 플로우 250±30 ㎜ 기준이 충족되는 것을 특징으로 하는 방통용 습식 자기충전 모르타르 조성물」을 제공한다.
