Zero-Crack Construction on the Fundamental Mass Concrete Using Double Bubble Sheets and Applying Low Heat Mixture
저발열 배합 및 이중버블시트에 의한 기초 매트 매스 콘크리트의 무균열 시공
Abstract
This study investigates the field application, Songdo the # 1st WORLD, on zero-crack construction of the fundamental mass concrete using double bubble sheets and applying low heat mixture. Experimental results of hydration heat analysis showed that crack modulus of concrete incorporating 20% of blast furnace slag cement was 1.0 in 120 hours, representing 50% probability of crack occurrence, thus requiring additional measures. As for a curing method, a specimen insulating two layers of vinyl chloride+double bubble sheets exhibited only
