Description

Some high absorption polymer with water have characteristics of discharging water when they are mixed in cement paste and being frozen without each particle combined below the freezing point. In this study, some basic properties of concrete mixed with this high absorption polymer absorbed mixing water, which was cooled by liquid nitrogen, in order to clarify to be applicable to precooling method were investigated. The results show that slump, air and strength of concrete mixed with high absorption polymer are roughly as same as conventional concrete and it can be largely reduced temperature of mixed concrete by using cooled high absorption polymer.
