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.
Claims14
A device for mixing a blend of dry ingredients with a liquid and for setting the ratio of the dry ingredients to the liquid, comprising:
- a sheet of flexible material arranged to form a reservoir and a planar skirt, said reservoir positioned at a central area of said sheet and shaped as an open-topped basin having a flat bottom, said basin arranged and sized to hold a predetermined volume of liquid, said skirt surrounding said basin, disposed generally parallel with said basin bottom, spaced from the plane of said basin bottom by basin sides extending between the basin bottom and the skirt, and extending from the top of said basin sides to the perimeter of said sheet;
- and
- a plurality of handles disposed around the perimeter of said skirt.
A method for batch mixing a dry blend of cement and aggregate with water comprising:
- providing a sheet of flexible material having a shallow, open-topped basin centrally located thereon, said basin arranged and sized to hold a predetermined volume of liquid, a planar skirt extending around the perimeter of said basin to the edge of said sheet, and a plurality of handles positioned on the skirt near the sheet edge;
- placing sufficient water into said basin to mix with a single batch of said cement and aggregate blend;
- pouring a batch amount of said cement and aggregate blend onto said sheet atop the water;
- raising a first of said handles to cause said cement and aggregate blend and water to fold toward the sheet side opposite said handle;
- lowering said first handle and raising a second handle on the opposite sheet side;
- and
- repeating said raising and lowering until said cement and aggregate blend is mixed with the water to form a concrete.
