Admixture for Cement Mortar Comprising Hydrophobic Silica and Preparation Method of Thereof
The present invention relates to an additive for cement mortar and a manufacturing method thereof. More specifically, the present invention relates to an additive for cement mortar, which can prevent the degradation of the physical properties of the cement mortar by reducing heterogeneity, which is a problem caused by the deliquescent properties of urea, and can also improve open time, water retention, and workability of the cement mortar. The present invention also relates to a manufacturing method of the additive for cement mortar. The additive comprises cellulose ether and urea powder.
본 발명은 시멘트 모르타르용 첨가제 및 그의 제조방법에 관한 것으로, 보다 상세하게는 요소의 조해성으로 인해 발생되는 문제점인 불균질을 해결하여 시멘트 모르타르의 물성 저하를 방지하고, 시멘트 모르타르의 오픈 타임(open time), 보수성, 작업성 등을 향상시키는 시멘트 모르타르용 첨가제 및 상기 시멘트 모르타르용 첨가제의 제조방법에 관한 것이다.
