Novel osmotic brick using desert sand as aggregate

The utility model discloses a novel osmotic brick using desert sand as aggregate, comprising a face layer of the osmotic brick and a bottom layer of the osmotic brick, wherein the face layer is fixed on the bottom layer, and the face layer and the bottom layer are both a colored sand layer of the desert sand. The sand size of the colored sand layer of the desert sand is 40-120 meshes. The face layer and the bottom layer of the osmotic brick are formed by uniformly mixing and pressing the desert sand, an aqueous high-molecular binder, an inorganic binder, and a coloring agent. The aqueous high-molecular binder is selected from one or a combination of an aqueous epoxy resin, a polyvinylacetatc resin and polyvinyl alcohol. The inorganic binder is Portland cement, soluble glass or the composition thereof. The coloring agent is selected form an inorganic pigment like medium chrome yellow or molybdenum chrome red. The novel osmotic brick reasonably utilizes the desert saw sand in a common pavior brick. Because the
