摘要： A composite plastering material and a method of making the same are provided. The composite plastering material includes a mixture of sand-silica and Abelmoschus esculentus powder. The composite plastering material has increased compressive strength depending upon the concentration of Abelmoschus esculentus powder used. The method of making the 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, and mixing water with the first mixture to produce the composite plastering material. Optionally, the method may also include milling the sand-silica prior to sieving and combining the sand-silica with the Abelmoschus esculentus powder. The composite plastering material may then be plaster cast, such as by pressing the composite plastering material in a hot press and drying the resulting composite material in an oven.

摘要： The cementitious mixture includes cement with a concentration of between about 5 wt % and about 20 wt %; powdered glass with a concentration of between about 5 wt % and about 35 wt %; fly ash with a concentration of between about 20 wt % and about 40 wt %; sand with a concentration of between about 18 wt % and about 25 wt %; a poly(carboxylate ether)-based superplasticizer with a concentration of between about 0.8 wt % and about 1.2 wt %; and water with a concentration of between about 14 wt % and about 16 wt %. Alternatively, the fly ash may be replaced with ground granulated blast furnace slag (GGBFS). The powdered glass is preferably powdered recycled glass cullet. The glass cullet may be ground to have an average particle size of about 10 μm or less. The sand may be red dune sand, and the cement may be Portland cement or white cement. The cementitious may also include polyvinyl alcohol (PVA) microfibers.

摘要： Clay polymer nanocomposites may be mixed with an aggregate material and heat treated to make a structural stabilizer. In an embodiment, the composition is a structural stabilizer resulting from thermal casting and heat treatment. The structural stabilizer does not include cement or water. The heat treatment may be any suitable heat application, including microwave heating, convection oven heating or heating in thermal mixers. The structural stabilizer can be rapidly synthesized to provide high compressive strength and high homogeneity, and to be substantially free of fractures and cracks. Methods of repairing cracks in concrete and stabilizing soil, rock and sand dune formations using the structural stabilizer include thermal casting. Thermal casting ductile concrete molds can include a coating of aluminum foil. The concrete is self-compact, ecofriendly, lightweight, self-repairing and self pre-stressing with homogeneity and low density. The concrete resists steel corrosion, sudden collapse, and does not produce pollution.
