CONCRETE ADMIXTURE AND A METHOD OF MANUFACTURING THE STEAM CURING CONCRETE
The present invention relates to a concrete admixture of a steam curing concrete structure and a method of manufacturing the same, capable of reinforcing compressive strength and flexural rigidity of the steam curing concrete structure, improving productivity by reducing an initial setting time, and improving durability of the concrete structure. The method of manufacturing the concrete admixture of the steam curing concrete structure includes the steps of: a) producing a first composition by adding water, metakaolin, alumina cement, a catalyst, sodium hydroxide, and borax; b) producing a second composition by mixing liquefied sodium silicate and a polycarboxylic acid-based water reducing agent; c) producing a third composition by mixing water and anionic surfactants; and d) producing a concrete admixture by mixing the first composition, the second composition, and the third composition.
a) 물, 메타카올린, 알루미나 시멘트, 촉매제, 수산화나트륨 및 보락스를 첨가하여 제1조성물을 제조하는 단계와, b) 액상의 규산나트륨, 폴리카본산계 감수제를 혼합하여 제2조성물을 제조하는 단계와, c) 물과 음이온계면활성제를 혼합하여 제3조성물을 제조하는 단계와, d) 상기 제1조성물, 제2조성물, 제3조성물을 혼합하여 콘크리트 혼화제를 제조하는 단계를 포함한다.
