    Abstract: Compositions and methods for grinding inorganic particles, such as cement, cement clinker, limestone, or other inorganic particles, involving a grinding efficiency enhancing additive comprising a crude glycerin byproduct, obtained through the use of heterogeneous catalyst processes in biodiesel fuel production. The molecules generated through the use of such heterogeneous catalytic processes result in a crude glycerin that confers good additive formulation stability, while avoiding or minimizing large quantities of undesirable compounds such as fatty acids, fatty acid esters, and salts.

    Abstract: Described are admixture composition and method for integrally waterproofing cementitious compositions, such as concrete and mortar, wherein an organosilicon compound (e.g., silane) is mixed with animal oil, vegetable oil, or mixture thereof, and defoaming agent. The organosilicon/oil mixtures of the present invention enhances the water repellent efficacy of the organosilicon, even as it displays inherently greater product stability, as compared to emulsion-based (and thus substantial free-water containing) admixture formulations of the prior art. Cementitious materials made in accordance with the present invention demonstrate excellent air consistency and air neutrality.

    Abstract: Methods for plasticizing cementitious mixtures having relatively high water/cement ratio (at least 0.40 or higher) are surprisingly improved in terms of dosage efficiency, compared to conventional “superplasticizer” polycarboxylate polymers, when the comb-type carboxylate copolymer is formed from two different polyether side chains, specifically selected monomer constituents: (A) first polyoxyalkylene monomer represented by structural formula (R1)(R3)C═C(R2)((CH2)m(CO)nO(CH2)o(AO)pR4) wherein (AO)p represents linear alkylene oxide and p is an integer of 5-23; (B) second polyoxyalkylene monomer represented by structural formula (R1)(R3)C═C(R2)((CH2)m(CO)nO(CH2)o(AO)qR4) wherein (AO)q represents linear alkylene oxide groups and q is an integer of 20 to 200; (C) unsaturated carboxylic acid monomer represented by (R5)(R7)C═C(R6)(C(O)OM) wherein M represents an alkali metal, and the ratio of component A to component B is 20:80 to 50:50; and, optionally, (D) a water-soluble monomer represented by (R8)(R9)C═C(R10)(X) wherein R8, R9, and R10 each represent hydrogen or methyl group, and X represents C(O)NH2, C(O)NHR11, C(O)NR12R13, OR14, SO3H, C6H4SO3H, or C(O)NHC(CH3)2CH2SO3H, or mixture thereof, wherein R11, R12, R13, and R14 each represent a C1 to C5 alkyl group.

    Abstract: Methods and systems of the invention, for achieving a liquid-applicable, aqueous-based coating composition that forms a water-impermeable, vapor permeable barrier coating when applied onto a construction surface and allowed to dry, involve mixing together separate first and second components, wherein the first component comprises an acrylic emulsion, flame retardant, clay, and optionally at least one additive selected from thickeners (e.g., cellulosic), fillers, and other conventional additives; and wherein the second component comprises a freezing point depressing agent with a specific type of thickener selected from the group of associative thickeners, alkali soluble emulsion thickeners, or mixture thereof, to obtain the liquid-applicable coating. The present invention achieves low temperature film formation without reliance upon calcium nitrite, calcium nitrate, or sodium chloride type of freezing point depressing salts. The coating can be applied at low (e.g., sub-freezing) temperatures onto a construction surface such as wood, fiberboard, gypsum, cement, concrete, and other building substrates to achieve an effective barrier membrane.
