  • 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: 9260350
    Abstract: The present invention relates to a cementitious coating with hydrochromatic properties for micro-concrete or normal concrete, mortar, or other construction materials based on cement and ceramics. This cementitious coating in acrylic solution changes its opacity depending on the presence of water and moisture. This color change is reversible after some drying time leaving invisible the markings already existing on the substrate. This cementitious coating comprises the following components, in percentage in weight of the components relative to the total weight of the composition: a) 0.5-30% of hydrochromatic acrylic copolymer emulsion; b) 5-30% of white or gray Portland cement; c) 0.1-30% of finely ground limestone filler; d) 0.01-2% of powdered super-plasticizer; e) 0.01-3% of modified polyvinyl resins; f) 0.01-5% of dispersant of vinyl acetate and ethylene copolymers; g) 15-70% of aqueous acrylic emulsion; and optionally h) 0.1-15% of inorganic pigments.

  • Patent number: 9162924
    Abstract: A novel mortar mix and mortar formed therewith. The mortar contains sand, lime, cement and microtubes in a mixture thereof. The microtubes assist in wicking moisture directly through a wet mortar compound formed by adding water to the mortar mix. Wicking moisture directly through the mortar decreases the reliance on a continuous, unobstructed cavity behind the masonry wall, as well as prevent cracking from water's freeze-thaw cycle. It also allows water to pass through the mortar in a similar manner as the masonry, creating two in-sync cycles, rather then two disparate cycles for water flow. In various embodiments, the microtubes could be composed of cellulose, fabricated polymer or graphite.
