Abstract
The invention relates to a heavily-doped steel slag foam concrete building block and a preparation method thereof. The preparation method of the concrete building block comprises the following steps: evenly mixing slurry and a foaming agent solution, forming, demolding, and curing. The slurry comprises the following components in parts by weight: 50-150 parts of cement, 20-60 parts of steel slag, 10-60 of water, 0-8 parts of early-strength admixture, 0-3 parts of setting accelerator, 0-1.5 parts of fiber, 0-5 parts of water reducing agent and 0-5 parts of excitant. The foaming agent solution is formed by mixing a foaming agent and water in a mass ratio of 1:20-1:50 and then foaming. The volume of the foam generated by foaming the foaming agent solution is 20-100 times of the volume of the slurry. The excitant is desulfurized gypsum. In the invention, the heavily-doped extrafine steel slag powder is used for preparing the foam concrete building block, thereby implementing physical excitation of the activity of the steel slag, and avoiding the simple filling function of aggregate; and meanwhile, the desulfurized gypsum is added as the chemical excitant, thereby enhancing the properties of the concrete building block, solving the problem in treatment of desulfurizing slag, and changing wastes into valuable substances.
