The invention discloses a building formwork with a hard abrasive material on the surface. The hard abrasive material is arranged on the surface of the building formwork, and the building formwork is prepared from glass fiber enhanced thermoplastic resin. The hard abrasive material on the surface of the building formwork can enhance wear resistance of plastic, the problem that demolding use is affected due to abrasion in the using process of the building formwork is avoided, and demolding is easy when a mold is used for concrete forming demolding.
