ABSTRACT:
Single bag quantities of blended cement and aggregate are mixed with water to form concrete using a flexible mat that is arranged with a shallow central basin bounded by a flat skirt. A plurality of handles, suitably four, are provided in the skirt near the mat edge. A sufficient amount of water to mix with a single bag or batch of pre-blended cement and aggregate is placed in the basin, and the batch amount of cement and aggregate is then poured onto the mat atop the water. Two persons grasp the mat by way of adjacent handles and mix the water with the cement and aggregate by alternately raising and lowering diagonally opposite mat handles.
