ABSTRACT:
A concrete slab striker employs a counter-rotating roller to grade or strike off the surface of a freshly poured concrete slab while the concrete is still in the plastic state. An elongated roller is supported on a form bordering the concrete slab in engagement with the concrete surface. A manually movable support frame and pull device coupled to opposite ends of the roller allow workmen to pull the roller across the concrete slab. Simultaneously, the roller is rotated in a direction opposite to its direction of travel relative to the surface of the concrete slab. A thin coating of hardened concrete particles accumulates on the roller to impart a texturized surface to the concrete slab when cured.
