    Abstract: Method for grinding a solid in a vertical roller mill (VRM) and a cement composition prepared by the disclosed methods. A method comprises grinding a solid comprising a cement clinker under a water spray in the presence of a grinding stabilizing additive, wherein the grinding stabilizing additive comprises: (i) an alkanol amino acid compound or a disodium or dipotassium salt thereof having the structural formula: (I), (ii) a glycol; or a mixture of (i) and (ii), wherein the water spray level is reduced by at least 5% compared to a control. Cement compositions prepared by the disclosed methods have the pre-hydration level (Wk) equal to or less than 1.5%. The values and preferred values of R1-3 are disclosed herein.

    Abstract: The invention provides a waterproofing membrane which does not require a removable release sheet but which nevertheless bonds to post-cast concrete and facilitates water-tight sealing at membrane-to-membrane overlaps. The waterproofing membrane comprises a carrier and pressure-sensitive adhesive (PSA) layers, an inorganic particle layer having particulate bodies which are partially embedded in the PSA and which have an average particle size less than the average thickness of the PSA layer, and an anti-submarining nano-silica-containing coating layer attached to un-embedded portions of the inorganic particles to prevent total embedding into the PSA when the membrane is rolled or unrolled, whereby water-tight seams are facilitated between overlapped portions of adjacently installed waterproofing membranes, and whereby the water-tight seam is achieved preferably using only detailing or waterproofing tape and without the additional use of a liquid primer, mastic, or other coating.

    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 having specifically selected monomer constituents.

    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.

    Abstract: A composition for use as an additive for enhancing the strength of a cementitious composition, the composition comprising an alkanolamine comprising ethanoldiisopropanolamine (EDIPA) and optionally at least one selected from the group consisting of triisopropanolamine (TIPA), diethanolisopropanolamine (DEIPA), triethanol amine (TEA), and tetrakis-(2-hydroxyethyl)ethylenediamine (THEED); at least one set retarder selected from the group consisting of a gluconate salt, sucrose, corn syrup, and molasses; and at least one set accelerator selected from the group consisting of a thiocyanate salt, sodium chloride, and calcium chloride, wherein the alkanolamine and the set accelerator are present at a mass ratio of from 0.2 to 4.0 and the set accelerator and the set retarder are present at a mass ratio of from 1 to 10. The additive enhances the short term and long-term strength of cement when hydrated.
