The present disclosure relates to the technical field of solid waste recycling and fabricated buildings, and provides a solid waste large-mixing-amount concrete prefabricated laminated slab and a preparation method thereof. The solid waste large-mixing-amount concrete prefabricated laminated slab provided by the present disclosure comprises a prefabricated layer and a laminated layer. Transverse grooves and longitudinal grooves are formed in the surface of the prefabricated layer. During application, the grooves can be used for erecting pipelines, the contact area of the prefabricated layer and the laminated layer can also be increased, the combined effect of new concrete and old concrete is improved, the integrity of a floor slab is enhanced, and the effect of improving the overall stress capacity of the floor slab is achieved.

Solid waste large-mixing-amount concrete prefabricated laminated slab and preparation method thereof

Multi-solid waste activated concretes with high-silicon iron ore tailings and preparation methods thereof are disclosed. In at least some embodiments, the concrete is prepared from raw materials including 360-380 kg/mof a cement, 30-40 kg/mof fly ash, 30-40 kg/mof a modified ultrafine sand of high-silicon iron ore tailings, 930-950 kg/mof a waste stone of tailings, 870-930 kg/mof a fine sand of tailings, 160-170 kg/mof water, and 4-8 kg/mof an additive.
