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 system and method for monitoring and adjusting a constant flow asphalt manufacturing process includes monitoring the ratios of recycled material to virgin material to minimize costs and adjusting the mixture in real time. Pulverized asphalt shingle (PAS) material may be used as a source of recycled asphalt oil and fed to a mixing drum with real-time monitoring while making real-time adjustments to supplement the asphalt with new asphalt oil to the mixer. The systems and methods may also be used for monitoring, metering, and supplementing recycled aggregate from recycled asphalt pavement (RAP) with new aggregate. The systems and methods may use one or more processors or programmable logic controllers (PLC) to meter the addition of new materials.

A bio-composite plastering material and a method of making the same are provided. The bio-composite plastering material includes a mixture of sand-silica, Abelmoschus esculentus powder, and multi-walled carbon nanotubes. The bio-composite plastering material has increased compressive strength depending upon the concentration of Abelmoschus esculentus powder and multi-walled carbon nanotubes used. The method of making the bio-composite plastering material includes sieving the sand-silica to produce sand-silica of a uniform particle size, mixing powdered Abelmoschus esculentus powder with the sand-silica to produce a first mixture, mixing water with the first mixture to produce the bio-composite plastering material, and enhancing the bio-composite material by adding multi-walled carbon nanotubes. The bio-composite plastering material may then be plaster cast, such as by pressing the bio-composite plastering material in a hot press and drying the resulting bio-composite material in an oven.

Embodiments of the present disclosure related carbon-based structural unit (CSU). The CSUs include a cured composition. The cured composition includes about 1% to about 80% pyrolysis char (PC), about 0.1% to about 35% coal deposits, extracts, and residual tar (CDER) materials, and about 0% to about 99% pitch material. The CDER material includes a tetralin insoluble (TI), a deposit (De), a distillation residue (DR), and a residue (Re). A method of making a composition includes extracting a coal extraction residue (CER) from coal; fabricating pyrolysis char (PC) and a coal deposits, extracts, and residual tar (CDER) material from the CER; sieving and milling the PC into milled PC; and mixing the pyrolysis char (PC) and the CDER material to form a composition.

Provided herein are a method and a system for producing slabs, tiles or sheets of artificial stone, with a wide vein effect, comprising inorganic particles of different sizes and hardened binders, and which simulate the appearance of natural stone.

The present invention provides particular a novel composition for manufacturing plastic composites and a process thereof. Said invention provides a composition and a process utilizes any or all kind of plastic waste in manufacturing composites and thereby is economical and environment friendly. It utilizes any or all kind of plastic wastes includes road waste, soft & hard form of plastic waste. Moreover, it eliminates the use of cement and utilizes plastic wastes in manufacturing composites; therefore is environment friendly. Said present compositions utilizes plastic waste in manufacturing light weight composites that are highly stable with increased strength, shelf life and durability. Said composition is fire resistant with increased strength withstanding heavy load.

An air-dry clay moldable and workable for sculptural applications, comprising a formulation of: (1) caulk or caulk base material and (2) a thickening agent and/or a detackifier in sufficient proportions to form a clay that can air dry to a substantially solid form at room temperature. The clay may include both a thickening agent and detackifier. The caulk or caulk base material comprises by weight percent: 40-90%, or 50-80%, or 60-75% of the formulated clay.
