Abstract:
A filler material that includes a metal fluoride compound which is coated with silica. The filler material can be used in various types of covering agents. The filler material can be used partially or fully as a pigment extender in a covering agent such as paint to improve the properties of the paint. The filler material in the pigment extender can improve the hiding power of many types of paint formulations. The filler material in the pigment extender can be useful in flat paints that require relatively low sheen values. A pigment extender can include microcrystalline.silica, nepheline syenite and/or a silica coated metal fluoride.
Abstract:
An alkali resistant glass composition having improved durability to withstand highly alkali environments at elevated temperatures, such as curing of cementitious products in an autoclave, is conveniently formed from economical and abundant materials. The glass composition includes increased levels of calcium and iron, and relatively low levels of alkali metals, as compared to many other alkali resistant glass products, and comprises essentially of, by weight, >35% Si2O3, 1-25% CaO, 1-15% Fe2O3, 1-10% R2O, and an amount of Al2O3 such that the ratio of Si2O3:Al2O3 is greater than or equal to 1. Alkali resistance can be improved by forming a passivity layer on the surface of glass articles by treating the articles hydrothermally in a basic environment. Optionally zirconia and/or titania may be added to the composition to further improve alkali resistance.

Abstract:
A composite material and process for forming composite material. The composite material comprises a quantity of plastinated plant distributed within a matrix material. The process comprises separating a plant material into plant fibers plastinating the plant fibers and combining the plastinated plant fibers with a matrix material. The plant fibers may be selected form the group consisting of bamboo, hemp and flax. The plant fibers may be formed by crushing a portion of a plant. The matrix material may comprise Polyethylene Terephthalate (PET). The PET may be shredded and heated. The heated composite material may be formed into rebar and be arranged in a pattern within a concrete slurry.
Abstract:
A method of controlling the setting time of a geopolymer by coating aluminosilicate particles with nanoparticles to slow the geopolymerization reaction. The coating effectiveness of the nanoparticles may be enhanced by pretreating the aluminosilicate particles with a layer-by-layer assembly of polyelectrolytes. A geopolymer is formed by mixing about 39% to about 66% by weight aluminosilicate source, about 0% to about 40% by weight sand, about 19% to about 33% by weight of alkali activator solution, and about 1% to about 4% nanoparticles.
Abstract:
Glass composite coating systems herein may be used for industrial applications serving as a chemical barrier against substrate oxidation or other deterioration by corrosive agents, may prevent material build-up in process piping and equipment, may provide for improved bonding strength between concrete and reinforcing media, and may inhibit microbial build-up on exposed surfaces. Traditionally, glass coatings are emplaced on relatively pristine, pre-prepared surfaces. Glass composite coating systems described herein may be bonded to untreated substrates, without the need to clean, polish and/or pre-treat the substrate.

Abstract:
The present invention relates to a method of manufacturing composite particles that work as a binding agent, the composite particles containing a limestone portion, which is based on limestone particles or limestone silicate rock particles and which is mixed with a kaolin portion that comprises kaolin particles. In the method, the limestone portion or the kaolin portion is subjected to calcination before they are mixed with each other, or the mixture of these portions is subjected to calcination, whereby, the activated layer on the surfaces of the particles of, at least, one of the said portions that was formed in the calcination makes the particles of the portions to attach to each other into composite particles. The invention also relates to the composite particles thus produced, the concrete that is formed by these, and equipment that is suitable for the implementation of the said method.
