A method of forming a multi-use dry pavement from oily waste derived from hydrocarbons has the steps of combining the oily waste with calcium oxide so at as to suspend and homogenize the wastes, adding hydrogen peroxide and water to the oily mixture, and adding ammonium sulfate and water to the mixture. The hydrogen peroxide is mixed with equal amounts of water. The ammonium sulfate is mixed with an equal amount of water. The homogenization process continues until the mixed material forms a granulate. The granulate can be compacted and then used as a pavement.

A hot-pressed geopolymeric composition and producing method for making the ultra-high strength geopolymer are disclosed. The hot-pressed geopolymeric composition may include at least one aluminosilicate source and at least one alkali activator and optionally any kind of fillers. The ultra-high strength geopolymer with various densities can be produced by applying low hot-pressing pressure in a short time.

A non-sintered high-strength lightweight aggregate one-shot prepared from sulfur-based and alkaline-based solid wastes by stirring, granulation, and foaming, and a preparation method therefor and use thereof. The non-sintered high-strength lightweight aggregate is prepared from a sulfur-based solid waste, an alkaline-based solid waste, an auxiliary cementing material, a ferro-aluminum-sulfur cementing material, water, and a foaming agent as raw materials. Based on the mass of the total solid, the total content of the sulfur-based solid waste, the alkaline-based solid waste, and the auxiliary cementing material is 80-90 wt %, and the content of the ferro-aluminum-sulfur cementing material is 10-20 wt %. The mass ratio of the water to the total solid is (15-20):(80-85). The foaming agent accounts for 0.3-0.7% of the mass of the total solid. The mass ratio between the sulfur-based solid waste, the alkaline-based solid waste, and the auxiliary cementing material is (27-33):(27-33):(18-25).

The invention: a procedure to manufacture recycled waste concrete, and the recycled waste concrete itself, which is produced through a simple processing of various types of waste and is suitable for serving as a material to manufacture concrete products widely used in the construction industry, where such products include road bases, strip foundations, bases of houses, noise barriers, traffic barriers for highways/roads, lane separators, sandwich panels, to fill formwork and even, depending on the type of waste used, to build walls. The recycled waste concrete contains cement, water and shredded waste aggregates, such as shredded tyres and/or any shredded plastic waste, and/or any shredded scrap metal, and/or any shredded garden waste, and/or shredded mixed waste, and/or shredded fibre waste, and/or any shredded glass waste, and/or shredded and effectively neutralised municipal waste. As organic binding agent it contains homo-, co- and terpolymers, which can be dissolved and/or dispersed in water and do not contain or produce environmentally hazardous, volatile, organic hydrocarbons, and such polymers are made, for instance, by using vinyl chloride, vinyl esters of saturated, unsaturated and aromatic organic acids, vinyl butyral, ethylene, esters of acrylic acid, styrene, alkyl isocyanates, silanes and siloxanes, which may contain polyvinyl alcohols and/or cellulose ethers and/or other protective colloids. The invention is characterised by being produced by simply mixing the ingredients in the proportions given as listed below: 20-50 volume percent cement, 0.3-10 volume percent organic polymer binding agent, 8-30 volume percent water, and 50-100 volume percent shredded waste aggregate.

A cementitious composition includes (i) white Portland cement having a Blaine fineness between about 350 m.sup.2/kg and about 550 m.sup.2/kg, a D90 between about 11 m and about 50 m, and a total combined iron oxide, manganese oxide, and chromium oxide content of less than 1.0% by weight and (ii) a light color ground granulated blast furnace slag (GGBFS) having a Blaine fineness greater than the Blaine fineness of the white Portland cement, a D90 less than the D90 of the white Portland cement, and a total combined iron oxide, manganese oxide, and chromium oxide content of less than 2.0% by weight. The cementitious composition may optionally include at least one of additional SCM, aggregate, fibers, or admixture. The cementitious composition can be a dry blend, a fresh cementitious mixture, or hardened cementitious composition. The cementitious composition can be precast concrete, stucco, GFRC, UHPC or SCC.
