Abstract:
With the purpose of controlling inside and outside temperature difference of concrete and under the precondition of ensuring concrete strength, mix design was carried out in mass concrete baseplate construction of HNA Capital B18 Lot project. Various measures were adopted, such as adding high-volume of mineral admixture, reducing aggregate temperature, adding retarding water reducer and strengthening concrete insulated curing, etc., to reduce inside and outside temperature difference of concrete and control concrete crack. Concrete strength evaluation result showed that mass concrete structure reached C40P8 requirement and no crack and permeation occurred.
