A dental self-adhesive resin cement is provided comprising a two-component system. A first catalyst component includes one or more acidic monomers. A second base component includes one or more basic fillers. The mixture of the first and second components is polymerizable and has an initial pH that is acidic immediately after mixing and a pH of at least about pH 8 after polymerization.

The invention provides novel articles of composite materials having hollow interior channels or passageways, or otherwise being hollowed out, and formulations and methods for their manufacture and uses. These hollow core objects are suitable for a variety of applications in construction, pavements and landscaping, and infrastructure.

A method of manufacturing a catalytic sieve includes providing starting materials of an aggregate, a cementing agent, a sublimation agent and water. The sublimation agent (between 25% and 50% by weight of the cementing agent) is selected from molybdenum disulfide, tungsten disulfide, vanadium disulfide, copper sulfate, and combinations thereof. The aggregate contains at least 2% by weight of at least one transition metal. The method includes mixing the starting materials to achieve a mixture, placing the mixture into a form, and curing the mixture in the form to allow the mixture to become a solidified unit defined by a minimum dimension of thickness, length, width or diameter. The method further includes placing the solidified unit into a kiln, heating the kiln to 1115-1350 C., maintaining the kiln at the temperature for between 10-60 minutes per centimeter of the minimum dimension, and removing the solidified unit from the kiln.

A method for manufacturing a mineral-based porous granular material includes providing a starting material of at least 70 weigh % of an micaceous arkose rock material. The starting material is in a granular form having at least 50 volume % with a mean diameter of between about 0.060 mm and about 0.65 mm. The method includes placing the starting material into a bed on a support surface, placing the support surface containing the bed of the starting material into a kiln, and subjecting the bed of starting material within the kiln to a basic processing temperature of between about 1100 C. and about 1300 C. for a basic processing temperature processing time selected to transform at least 40 volume % of micaceous components in the micaceous arkose material into feldspar, and to evolve at least 30 volume % of metal sulfides within the feldspar from the feldspar as metallic oxides.

A reinforced composite product of concrete (14) reinforced by reinforcement mesh(s) (13, 13) of an aluminium alloy. where calcium hydroxide of the concrete is absent to avoid or reduce corrosion of the aluminium reinforcement by replacing cement with >35% active pozzolana and that the mesh can be made by slit-stretching or by punching a sheet aluminium metal. The aluminium mesh is advantageous for use as reinforcement in various concrete structures in corrosive environment and where traditional steel meshes are used today.

A precipitated calcium carbonate derived from plant matter may be used in place of or in combination with cementitious materials in various products and methods of making such products. The product may be a concrete comprising water and an aggregate in addition to the precipitated calcium carbonate derived from plant matter. The product may also be a soil cement comprising soil in addition to the precipitated calcium carbonate derived from plant matter.
