Abstract

PURPOSE:To increase cooling effect and to prevent even large concrete from generating the crack due to heat of hydration, by mixing cement, gravel, sand and granular ice. CONSTITUTION:This concrete is prepared by mixing cement, gravel, sand and granular ice. As aggregates, that is, gravel and sand, conventional ones can be used and, as the cement, known one can be used. This concrete is characterized in that granular ice is used in place of water used in general and it is pref. that granular ice has good flowability and rapidly melted to be uniformly mixed with other aggregates at the time of mixing. From this aspect, the granular ice is crushed so that the particle size thereof is pref. 10mm or less, more pref., 5mm or less, ideally, 3mm or less.
