Various methods for making material capable of forming structural composites are disclosed. For example, a particular method may include growing an amount of cyanotic organisms, separating cell walls of the cyanotic organisms from internal portions of the cyanotic organisms to form a purified algae extract, the purified algae extract being from the internal portions of the cyanotic organisms, and applying an effective amount of alkaline water to the purified algae extract to form a balanced algae extract having little or no chemical reactivity, wherein a pH of the alkaline water is a function of a pH of the purified algae extract.

A method for treating sludge, in particular polluted harbour sludge, includes the following operations:—mixing the sludge with concrete and/or stone gravel,—treating the sludge/gravel mixture by crushing in order to obtain crushed material, and—carrying out a screening operation on the crushed material, simultaneously to heat treatment, in order to obtain crushed material of at least two different particle sizes. The facility for treating gravel, in particular gravel mixed with sludge, capable of implementing the method, includes crushing elements (2), screening elements (4) associated with heating elements (5), and elements (3) for transferring between the two.

An artificial marble chip of the present invention comprises curable resin, metal fiber and/or inorganic fiber, and inorganic filler. The metal fiber and/or inorganic fiber preferably have an average length of about 1 to about 6 mm and an average particle diameter of about 10 to about 15 μm. An artificial marble according to the present invention is produced by using the artificial marble chip, curable resin matrix, and inorganic filler as main components. The curable resin is preferably selected from acrylic resin, unsaturated polyester resin, epoxy resin, or a copolymer thereof. The artificial marble according to the present invention is produced by the steps of: producing an artificial marble composition by mixing the artificial marble chip, the inorganic filler, and other additives into the curable resin matrix; and curing the composition at about 25 to about 180° C. The invention can also include the step of defoaming the composition prior to curing.

Crumb Rubber augmented masonry blocks including cement, aggregate, water, and crumb rubber. Crumb rubber is extracted from scrape tires after being processed and then mixed in specified percentages with aggregate, cement and water. In the present disclosure sand, which is used in the formation of conventional blocks, is replaced with crumb rubber to produce a sand-free masonry block containing crumb rubber. The developed crumb rubber masonry blocks satisfied the ASTM non-load bearing requirements in addition to satisfying the water absorption test.

A process for treating a tailings stream comprises (a) contacting (1) a gelling agent and (2) an activator with said tailings stream to produce a gel; (b) entrapping solids including sand and clay, and other solid particles with the gel; and (c) allowing the gel to strengthen and solidify to produce a trafficable deposit; wherein the tailings stream comprises water and solids, which solids comprise sand, clay and other solids particles, and wherein 5% by volume to 100% by volume of the solids have a particle size less than 0.05 mm, based on the total volume of the solids. The process may further comprises spreading the gel produced in step (a) or the trafficable deposit produced in step (c) over a surface. The present invention is particularly useful to treat tailings streams produced in processes to extract bitumen from oil sands ores.
