CEMENTLESS BINDER COMPRISING INITIAL SETTING TIME RETARDER AND PREPARATION METHOD THEREOF
A cementless binding material comprises: (a) a binding material mixture including fly ash, calcium hydroxide (Ca(OH)_2), and an alkali metal salt of carbonic acid; and (b) a retarder including at least one type of a compound having at least three hydroxyl groups or a salt thereof. The cementless binding material acid is manufactured by recycling industrial byproducts, and is an eco-friendly material. The cementless binding material has excellent compression strength, and particularly is easy to be used in a site by using the retarder and extending setting time.
(a) 플라이애쉬(fly ash), 수산화칼슘(Ca(OH)), 및 탄산의 알칼리금속염을 포함하는 결합재 혼합물; 및 (b) 3개 이상의 하이드록시기를 갖는 화합물 또는 이의 염을 1종 이상 포함하는 지연제를 포함하는 무시멘트 결합재는, 산업부산물을 재활용하여 제조되므로 친환경적이고, 압축강도가 매우 우수하며, 특히 지연제의 사용에 의해 응결시간이 길어져 현장에서 사용하기에 용이하다.
