A composition comprising a physical blend of discrete particulates such that the liquid absorbency is greater than the individual components and is greater than the expected absorbency based on the rule of mixtures. A composition comprising diatomaceous earth which may have a clump strength greater than 75% and in which the dry density may be less than 880 kg/m(55 lb/ft). The compositions exhibit synergistic absorbance, light density, high clump strength, low dustiness, and are suitable for industrial and household absorption and solidification, animal litter, and soil amendment.

Low density compositions with synergistic absorbance properties

A diatomaceous earth product with low crystalline silica content after at least one calcination step of between about 927&#xb0; C. (1700&#xb0; F.) and about 1149&#xb0; C. (2100&#xb0; F.) is disclosed. The product comprises natural diatomaceous earth and at least one binding agent comprising potassium silicate. Further the product comprises no more than about 4.0 wt % of crystalline silica and has a permeability in the range of about 0.3 darcy to greater than about 20 darcy. A process for making such diatomaceous earth product with a low crystalline silica content is disclosed. Moreover, a diatomaceous earth filter aid comprising such a diatomaceous earth product is disclosed.

Diatomaceous earth filter aid containing a low crystalline silica content

Described herein is a monolithic cementitious article with one or more pre-formed shaped regions. The shaped regions are generally channels that extend through a portion of the article or span the full article. The article includes one or more openings at least one of its ends. The article has a low apparent density with a high strength as well as high performance characteristics. The article when manufactured is suitable for use as a building product, such as siding, panel, trim, fascia, roofing, crown molding, decking, and fencing.

Cementitious trim articles

Cementitious formulations and their products with enhanced reactivity are provided. Formulations in certain embodiments may include at least one calcium source, a reactant and a filler in a hydrated environment, wherein the reactant, in one form, is crystalline silica that has been modified for reactivity. Enhancement of a reactant may include one or more modifications to its content, grind and/or the cement to silica ratio, as well as addition of one or more additives in the formulation, additives in the form of at least one alumina source, defoamer, catalyst and/or a clay.
