Abstract: A limestone based masonry veneer composition is described that may be molded, blown, sprayed, troweled, or otherwise applied to interior and exterior surfaces. The composition provides an aesthetic resurfacing, cladding and/or overlay coating. The composition is capable of being pigmented, textured, sculpted—or otherwise formed into an aesthetic, realistic, architecture, suitable as a stone veneer, an example of which is Blown Stone®, by Stone Coat®. Texturing or sculpting may occur about 1 hour and up to about 12 hours after applying the composition. The final composition is hydrophobic and breathes. Air carbonation allows the formation of a predominantly very pure calcium carbonate or limestone when fully cured, which prevents mold and algae growth and allows for autogenous healing with an increase in unit weight over time, ensuring an overall high compressive strength that endures over time.

Abstract: The present invention relates to an accelerator for hydraulic binding agents, comprising at least one phosphoric acid ester of a multivalent alcohol and at least one calcium compound. The accelerator according to the invention is capable of producing a very fast-curing mortar or concrete composition which has a high early strength and, nevertheless, very favorable processing properties and thus allows early dismantling or early loading and does not cause any losses in the final strength.

Abstract: A dry mortar mixture based on at least one hydraulic and/or latently hydraulic binder which in the made-up and not yet cured state has firm properties is claimed. The novel dry mortar mixture is characterized in that it contains at least one representative of a dispersant and at least one compound having superabsorbent properties. This mixture makes it possible to carry over the advantages of known tile adhesives for horizontal application to vertical application possibilities.

Abstract: An agglomerate is provided that can include an aluminosilicate (ash) base material and one or more of a binding agent or leach reduction agent. Each of the agglomerate and binding agent can include no more than about 25 wt. % cement.

Abstract: Magnesium phosphate cement binder systems and method for providing magnesium phosphate cements are described. In an embodiment, a magnesium phosphate cement binder system may include magnesium oxide that has been calcined at a temperature of between about 900° F. to about 1800° F. The magnesium phosphate cement binder system may also include a phosphate material. Other formulations, compositions, and methods are also described.

Abstract: Despite the excellent properties associated with Magnesium OxyChloride (Sorel) based cements and Magnesium OxySulfate based cements, water and corrosion resistance has been limiting factors for achieving greater commercial applications. Such issues can be addressed by incorporating various alkali metal phosphates, such as Magnesium mono- or dihydrogen phosphate (MgHPO4 or MgH2PO4) with alkali metal fatty acids; such as Magnesium Stearate; and metal or alkali metal sulfates such as Aluminum Sulfate or Magnesium Sulfate. Water resistance is further enhanced by either pre-carbonating the mix water or the liquid magnesium chloride phase of the cements, or by adding a carbonate into the powder phase. Accelerated cure of this system has also been obtained by using various inorganic metal oxides. Additionally, improved corrosion resistance is achieved through the use of certain phosphates, zeolites, nitrites and other novel additives.

Abstract: The present invention is drawn to a composition for cast-coating on ink-jet media. The composition includes a liquid vehicle, silica particulates, and an internal release agent. The composition is substantially free of polymeric binder and can improve the glossiness of a porous particulate-coated ink-receiving media by at least 2 gloss units at 20 degrees. The silica particulates can be suspended in the liquid vehicle at about 1-35 wt %, and can have a particle size of less than about 150 nm. The internal release agent can be present at about 0.5-10 wt %.

Abstract: A waterproof cements mortar or concrete compound is described. The waterproof compound contains a synergically effective quantity of a composition of water repelling and water reducing agents that are added to the waterproof compound as it is manufactured. Also described are synergic compositions for waterproofing and manufacturing methods for producing said waterproof compounds.

Abstract: An object of the present invention is to provide a leakage water cut-off agent that has an excellent power to seal a water leakage site by a simple process without damaging the appearance of a building. A leakage water cut-off agent of the present invention comprises (a) a surfactant, (b) an aluminium compound and (c) a basic substance, and further comprises water if necessary.

Abstract: Methods and compositions useful for increasing water resistance of a surface associated with a concrete, masonry or wood building material as disclosed herein. The method comprises the steps of applying a selected amount of an aqueous treating solution to the surface, wherein the aqueous treating solution includes a hydrophobic anion salt dissolved in water; allowing a portion of the aqueous treating solution to absorb into the surface; and evaporating the water to yield a treated surface having increased water resistance. The composition comprises a major amount of cement and a minor amount of a hydrophobic anion salt. The major amount of cement may be Portland cement, and the minor amount of hydrophobic anion salt may be potassium stearate, sodium stearate, as well as combinations thereof.

Abstract: Compositions for lightweight, waterproof, cementitious materials comprise portland cement, aggregates, two admixtures, and water. A first admixture comprises a major portion of calcium chloride and minor portions of sodium silicate and a wetting agent. A second admixture comprises an emulsion of ammonium stearate. Methods for producing cementitious materials include a process for manufacturing strong, lightweight, waterproof building products such as roofing tile, imitation bricks, and the like.

Abstract: Masonry cement additives are provided which, when interground with Portland cement, produce a masonary cement having superior workability, plasticity and board life, while unexpectedly also having advantageously low levels of entrained air. The additives of the invention enable the masonry cement producer to obtain these desired properties without replacing the limestone component of the masonry cement with more costly lime.The additives of the invention may be provided in aqueous solution, and thus, unlike emulsion additives, are stable for long periods of storage, even when subjected to extreme temperature excursions and cycling.The additives of the invention comprise a salt of stearic acid; a set retarding carbohydrate; an ethylenic glycol elected from the group consisting of mono-, di-, tri-, and tetraethylene glycols; and a cellulose ether.

Abstract: An additive for, a method of adding thereof to uncured mixes for and resulting cured cement-type concreations such as cured embodiments of concrete, marcadam, and roof-top shingles each exhibiting improved heat and freeze-thaw durability resulting from reduced efflorescence and stability against sun ultraviolet light exposure.
