The invention relates to a composition for making flooring material comprising resin and particles comprising ammonium quaternary salt. The resin is generally an unsaturated polyester resin. The flooring materials, or engineered stone slabs from which the flooring materials or other material can be formed, are generally made from combining the resin, particles, inorganic particulate material and an initiator and allowing the resin to cure. The flooring material composition may be cobalt free. Metal catalysts may be used to cure the resin.

The present invention discloses cement mortar containing excavated soil prepared by replacing natural sand with engineering soil, and a preparation method therefor and an application thereof. The preparation method includes drying and grinding waste engineering soil taken from a construction site first, sieving and mixing it to form recycled engineering soil, and putting the recycled engineering soil and natural sand into a mortar mixer according to a certain proportion to form a sandy soil mixture; then pouring water and cement into the mortar mixer, adding a part of the sandy soil mixture and a part of a water-reducing admixture, and evenly stirring; and finally, adding the remaining sandy soil mixture and water-reducing admixture, and evenly stirring to obtain the cement mortar containing excavated soil.

An object of the present invention is to provide a building large porcelain panel that prevents the efflorescence.

As the solutions, a building large porcelain panel according to the present invention is formed by kneading a raw material formulation containing, as a main material, a refractory aggregate, a glassy raw material, and cement, and subjecting the raw material formulation to molding and then firing, wherein the building large porcelain panel has a Na.sub.2O content of 1 mass% or less in an entire chemical-component composition of the building large porcelain panel fired. In addition, the building large porcelain panel has a Na2O content of 1% or less and containing 0.5 to 7% of BaO and 0.5 to 8% of B.sub.2O.sub.3 (12% or less of the BaO and the B.sub.2O.sub.3) at mass-based chemical component values.

The present invention relates to geopolymer compositions, sintered geopolymer articles from the geopolymer compositions and processes for manufacturing sintered geopolymer articles from the geopolymer compositions. The invention provides a process of producing a sintered geopolymer article containing a sintered geopolymer composition, wherein the sintered geopolymer composition comprises a sintered geopolymeric matrix, said process comprising the steps of: (1) forming a geopolymer composition comprising at least one aluminosilicate precursor, an alkali activating agent and water, wherein in the geopolymer article, the aluminosilicate precursor particles are at least partially coated by the alkali activating agent; and (2) firing the geopolymer article to sinter the geopolymer composition, wherein the alkali activating agent is capable of at least partially activating and dissolving the aluminosilicate precursor particles during at least a portion of the firing step, and wherein the firing of the geopolymer article includes a geopolymer composition sintering stage.

The present application is directed to a composition that includes a polymer comprising two or more units of monomer A, with monomer A being a radically polymerizable plant oil, animal oil, synthetic triglyceride, or mixture thereof and an epoxidized vegetable oil, an epoxidized fatty acid, or an epoxidized fatty ester. The present application is also directed to further compositions, methods of producing a liquid cement composition, and methods of paving.

A system and associated methods for processing unhardened concrete are disclosed. It at least one embodiment, the system for processing unhardened concrete includes a means to estimate a quantity of returned concrete; a foam adder to add foam to the quantity of returned concrete; a mixer to mix the added foam and returned concrete together to create treated concrete; a discharger to discharge the treated concrete; a discharge area configured in which to allow the treated concrete to set and harden; a converter to convert the hardened treated concrete into a particulate or aggregate form; and a user to determine the specific utilization of the particulate or aggregate form loose material.

Plastomer-modified asphalt binders meeting MSCR specifications, asphalt paving materials with such asphalt binders, and methods for fabricating such asphalt binders are provided. The asphalt binder contains a base asphalt and a plastomer. If the plastomer has a drop point no greater than about 139° C., the asphalt binder further contains sulfur; sulfur-containing compounds, such as hydrocarbyl polysulfides and thiuram disulfides; phenolic resins; metal oxides; or a combination thereof. The asphalt binder is substantially free of elastomer.

The invention generally relates to a method of making a plastic aggregate, and its use to make concrete products. The aggregate is formed by providing a granulated waste plastic material, introducing the granulated waste plastic material into an extruder having a die, the die having a ratio of die nozzle open area to die land area of about 1:10 to about 1:40, and extruding the granulated waste plastic material through the extruder to generate an extruded plastic aggregate. The method can include the presence of controlled cooling, the addition of additives and treatment of the surface of the aggregate to produce a desired aggregate that can be used to make a concrete product with desired properties, such as compressive strength and weight.
