    摘要: Cementitious compositions and methods for producing the cementitious compositions are described herein. The methods can include mixing a compound of the general formula MaSibXcOd, MaSibXcOd(OH)e, MaSibXc(OH)e, or MaSibXc(OH)e.(H2O)f, wherein M comprises a metal that can react with carbon dioxide in a carbonation reaction to form a carbonate, Si forms an oxide during the carbonation reaction, X is an element other than M or Si, a, b, d, e, and f are greater than zero, and c is zero or greater, with a rapid setting hydraulic cement to produce a cementitious mixture. The methods can further include hydrating the cementitious mixture and carbonating the cementitious mixture. Carbonating the cementitious mixture can occur simultaneously with hydrating the cementitious mixture or subsequent to hydrating the cementitious mixture. In some embodiments, the non-hydraulic cement can comprise wollastonite. The hydraulic cement can be in an amount of from 5 wt % to 80 wt % of the cementitious composition.

    摘要: The present invention is a fly ash filler or filler blend having a particle size distribution with at least three modes that can be combined with a polymer at higher filler loadings to produce a filled polymer for polymer composites that, in many cases, can produce improved mechanical properties for the polymer composites over polymer composites using conventional fillers. As a result, superior polymer composites (e.g. those used in carpet backing) can be produced at a lower cost than conventional polymer composites. The present invention also includes a method for producing a polymer composite, comprising the steps of combining a polymer with a fly ash filler or a filler blend having a particle size distribution with at least three modes to produce a filled polymer and producing a polymer composite with the resulting filled polymer. The present invention further includes a method of determining what fly ashes can be used as fillers for polymer composites.

    摘要: The present invention is an admixture for cementitious compositions that provides both good flowability and high early strength as is desired in the art. The admixture of the invention includes a superplasticizer comprising a water-soluble modified acrylic copolymer and at least one accelerant selected from the group consisting of salts of thiocyanic acid, water-soluble alkanolamines, ethylene oxide adducts of ethylenediamine, and morpholine derivatives. The combination of the superplasticizer and the accelerant used in the invention surprisingly has a synergistic effect on the early compressive strength of the cementitious composition and also enhances the W/CM ratio and the flowability of the cementitious composition.
