Preparation method for doped-glass micro powder foam concrete plate
The invention discloses a preparation method for a doped-glass micro powder foam concrete plate, and belongs to the field of concrete. According to the preparation method, portland cement and coal ash are mixed to obtain a mixture I, pretreated toughened glass powder and river sand aggregate are added into the mixture I to obtain a concrete-based slurry, then additives such as hydroxymethyl cellulose are added to be mixed with the slurry to obtain a mixture II, and forming of the mixture II is realized in a grinding tool to obtain the doped-glass micro powder foam concrete plate. According to the plate, waste toughened glass micro powder which is spherical in surface configuration and relatively large in specific surface area is doped in concrete, so that gaps between cement particles and gel products are effectively filled, cement stones and a limiting surface are compact, the concrete porosity rate is greatly reduced, the chloride diffusion resistance and the durability of the concrete are greatly improved, two solid wastes, namely the waste glass and the waste concrete, are utilized comprehensively, and cyclic utilization of municipal wastes and waste concrete resources is facilitated.
