Abstract: A cleaning sponge that efficiently utilizes melamine to effectively remove dirt and contaminants from a surface. The cleaning sponge includes a first sponge layer, a second sponge layer, a solidified detergent layer, a plurality of first pores, a plurality of second pores, and a plurality of third pores. The first sponge layer and the second sponge layer are connected to the solidified detergent layer on either side and provide protection for the solidified detergent layer against degradation. The plurality of first pores is distributed throughout the first sponge layer. The plurality of second pores is distributed throughout the second sponge layer. The plurality of third pores is distributed throughout the solidified detergent layer. The plurality of first pores and the plurality of second pores are in fluid communication with each other through the plurality of third pores. Water may flow through the cleaning sponge to create an effective surfactant.

Abstract: A spiral rebar weldable metal rod with a constant or variable pitch of between 1 and 10 times a diameter of a cylinder into which the rod is inscribed; with a planar cross-section having at least two petals connected to the central section and separated from each other by gaps. The triangular petals are connected with the central section by their vertices; the petal edges distant from the central section are circular. The rebar has ribs; the ribs' height is between 0.5 mm and 1.0 mm and distances between the ribs are between 5 mm and 15 mm.

Abstract: Disclosed a reinforcement structure for reinforced concrete and methods for manufacturing thereof. In one aspect, the reinforcement structure includes a rod comprising a spiral strip having a pitch between 1.0 and 10.0 times a width of the strip and a ratio of thickness of the strip to the width of the strip in a range of 1:4 to 1:10. The surface of the spiral strip may be entirely or partially corrugated with ribs of arbitrary shape and having height in a range of 0.05% to 0.30% of the thickness of the strip. In another aspect, method for manufacturing a reinforcement structure comprises flattening a wire rod into a flat strip, corrugating it with ribs, and twisting the ribbed strip into a spiral of the specified pitch.
