  • Patent number: 9919452
    Abstract: A brick includes a thermoplastic material, such as high density polyethylene (HDPE), and a cement-containing material. The brick may be made by mixing thermoplastic material and dry, uncured cement-containing material. This mixture is placed in a mold. The mold is heated while the mixture is compressed to melt or soften the thermoplastic material and to bind the particulate material in the mold into the shape of a brick. After the hardened brick is removed from the mold, the surface of the brick may be sprayed with water to cure cement-containing material on the surface of the brick.

  • Patent number: 9656917
    Abstract: The present invention relates to a white or colored cementitious mixture for the manufacture of micro-concrete or normal concrete, mortar or pastes with thermochromatic properties, i.e., changing its color depending on the temperature at which the material is exposed.

  • Patent number: 9546110
    Abstract: The present invention provides a composition and method for modifying a hydratable cementitious composition such as concrete or mortar using at least three different, distinct carboxylate polymers, even when clay is present in the concrete or mortar that would otherwise diminish dosage efficiency of polycarboxylate polymer used as dispersant. The three polycarboxylate polymers, designated as Polymer I, Polymer II, and Polymer II, are derived from monomer Components A, B, and C wherein Component A is an unsaturated carboxylic acid, Component B is a polyoxyalkylene, and Component C is an unsaturated carboxylate ester. The component molar ratio ranges for A:B:C are different as between Polymers I and II; while a distinct component molar ratio A:B+C is identified for Polymer III. When treated with these three different polycarboxylate polymers, the hydratable cementitious composition is surprisingly enhanced in terms of initial workability and slump retention, especially if clay is present.

  • Patent number: 9359253
    Abstract: A concrete composition and method include a portion of fine aggregate bearing a coating of a polymer, which may be a continuous coating layer or a layer of powdered, discrete particles embedded in a binder. The polymeric coating may be a super absorbent polymer (insoluble in water, but absorbing water), or another polymer such as the acrylamides, co-polymers thereof, polyacrylamides, or the like (soluble in water). The coating absorbs water, but particles are too small to form significant voids. Water is absorbed into the concrete mix in far greater proportions (e.g. w/c ratio over 0.5) improving workability, doubling workability time, and improving ultimate compressive stress (strength).
