Abstract:
A form for concrete strike-off includes a pan adapted to float on a plastic concrete surface, a rigid straightedge, and a support. The straightedge is coupled on one end to the pan and the support is coupled to the opposing end of the straightedge with the straightedge thereby defining a reference elevation for concrete strike-off operations.
Abstract:
A method of fabricating an integrated concrete slab includes places a first concrete mixture on a base to form a slab having a surface region in a plastic state. Next, a second concrete mixture in a plastic state thereof is placed on the surface region while the surface region is in its plastic state. The second concrete mixture includes concrete with approximately 3-9 pounds of stretchable fibers mixed in each cubic yard thereof.
Abstract:
An integrated concrete slab includes concrete with stretchable fibers mixed therein covering and partially integrated with a portion of concrete that contains either no fibers or relatively few fibers mixed therein.
Abstract:
A form for concrete strike-off has a rigid straightedge assembly and a support coupled to one end of the straightedge assembly. The straightedge assembly includes a grate coupled to the bottom edge of a support bar. The grate extends away from the support bar with a top surface of the grate defining a plane on at least one side of the support bar. In use, a portion of the straightedge assembly defines a reference elevation for concrete strike-off operations.
