Unfired masonry block based on surface layer reinforcement and preparation method thereof

The invention discloses an unfired masonry block based on surface layer reinforcement and a preparation method thereof. The unfired masonry block based on surface layer reinforcement comprises a cement soil block and a cement-based reinforcement layer. The cement soil block raw materials comprise waste soil, cement and water. The method comprises the following steps: stirring waste soil, a small amount of cement and water to obtain a mixture, loading the mixture into a mold, pressing and molding by pressure, and naturally curing to obtain the cement soil block. And a cement-based reinforcing layer with a certain thickness is applied to the outer layer of the cement soil block. The unfired masonry block prepared by the invention has the characteristics of excellent physical properties, high strength, good durability, low cost, less carbon emission, high utilization rate of muck and mud and the like. The cement soil blocks in the unfired masonry block body are used as internal filling materials, the requirement
