Concrete admixture and concrete premix formed by same
The invention discloses a concrete admixture and a concrete premix formed by the same. The admixture is made by grinding blast furnace slag, coal gangue, waste limestone, coal ash, oil shale slag and flue gas desulfurization gypsum according to a certain proportion, and then is applied to the concrete premix to replace part of cement, so that the cement content is reduced, and the concrete performance can be greatly improved. The concrete admixture and the concrete premix formed by the same effectively utilize industrial residues, change waste material into things of value, can effectively reduce pollution of the industrial residues on the environment; furthermore, after the admixture is used, the porosity of the concrete is reduced, the density of the concrete is added, and thereby the early strength of the concrete is improved, the concrete workability is improved, and the construction requirements of the engineering project are met.
