THICKENER FOR HYDRAULIC COMPOSITION, ONE-COMPONENT WATER-REDUCING AGENT, AND PREPARATION OF HYDRAULIC COMPOSITION
The present invention relates to a thickening agent including (A) water-soluble cellulose, (B) an anti-foaming agent, and (C) a gum material. According to the present invention, the use of a single-component water reducing agent having stable dispersibility suppresses the scattering of water-soluble cellulose when the addition amount of the water-soluble cellulose is low. Accordingly, the present invention can use the desired water-soluble cellulose ether to prepare a hydraulic composition having excellent bleeding suppression.
본 발명은, (A) 수용성 셀룰로오스에테르, (B) 소포제, (C) 검류를 포함하는 수경성 조성물용 증점제에 관한 것이다. 본 발명에 따르면, 안정된 분산성을 갖는 1제형 감수제를 사용함으로써, 수용성 셀룰로오스에테르의 소량 첨가 시의 비산 등을 억제하여, 원하는 수용성 셀룰로오스에테르가 첨가되어, 블리딩 억제 등이 우수한 수경성 조성물을 제조하는 것이 가능하다.
