Abstract
The apparatus for making cooled concrete of this invention produces cooled fresh concrete by cooling the aggregate (or gravel). The aggregate is cooled by immersion in a cooling water bath accommodated in a cooling water tank. The cooling water in the tank is cooled by a heat exchanger, which in turn is cooled by a forced cooling device. The aggregate is immersed into the cooling water bath by a supply and ejection apparatus, which also removes the cooled aggregate from the cooling water bath. The cooled aggregate is supplied to a cement mixer where it is mixed to become cooled fresh concrete.
