Abstract: The present invention provides compositions and methods relative to controlling hydration onset of an alkaline earth metal oxide such as calcium oxide, comprising heating an inorganic alkaline earth metal oxide to sub-calcination temperatures in the presence of organic material comprising a carbohydrate, an amino-carboxylic acid, a hydroxycarboxylic acid, or a mixture thereof. Preferred treated particles comprise at least 40% and more preferably at least 80% by dry weight calcium oxide which is heated in the presence of ascorbic acid and a starch. Treated particles of the present invention manifest an unexpected, surprising hydration induction postponement behavior as demonstrated through calorimetric testing.

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 methods and compositions for treating clay-bearing aggregates, particularly those used for construction purposes, whereby inclusion of fines is maximized due to minimization of clay washing which tends to remove such fines, and whereby performance of the aggregate-containing construction material is enhanced. Exemplary methods comprise introducing to clay a water-soluble, functionalized polyamine comprising a water-soluble polyamine formed by reacting an amine compound with an epoxy compound, the polyamine thus reacted being functionalized through the use of certain halide, sulfate, or epoxy compounds.

Abstract: Disclosed are surface retarder composition and method for etching cementitious materials which achieve a desirable light “acid etch” look without using muriatic (hydrochloric) acid or sand blasting, removing the human health and environmental concerns. Formulations in accordance with embodiments disclosed herein are easier to remove from formwork or molds after demolding than conventional retarder paints. Surface retarders prevent the hydration of cement particles, which allows the uncured layer of paste next to the form to be removed such as by washing with water or other fluids, or by brushing, revealing aggregates. Also disclosed are molded cement and concrete materials or articles exhibiting such light etch.

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.

Abstract: The present invention provides methods and articles for achieving puncture-resistant waterproofing membranes and for waterproofing building and civil engineering surfaces without requiring the use of separate protection boards. Exemplary membranes and methods of the invention rely on relatively thin, flexible composite layers to provide impact resistance while yet facilitating seaming between adjacent installed membranes and minimizing formation of wrinkles, leakage channels, and “fish mouth” openings, particularly at substrate details or other surface irregularities.

Abstract: A pressure-sensitive adhesive (PSA) composition and method of use across a wide operable temperature window. The PSA composition includes a triblock copolymer rubber with relatively low diblock content, an aliphatic tackifier, an aromatic tackifier, and an oil-based plasticizer. The combination of components results in the PSA having a phase-separated morphology, where the PSA includes two domains that do not mix with each other. This morphology’ results in superior performance of the PSA across a wide range of temperatures, such that separate adhesives for low temperatures and high temperatures are no longer required.
