Abstract: A method for producing a submicron-/nano-jute carbon/epoxy composite anti-corrosion coating is described. The method includes heating a jute stick, grinding the jute stick to form a first powder; pyrolyzing the first powder to form a pyrolyzed carbon; grinding the pyrolyzed carbon to form a second powder; ball milling the second powder under the wet conditions to form a submicron-/nano-jutecarbon; mixing the submicron-/nano-jutecarbon, and an epoxy resin to form a first mixture; mixing a hardener with the first mixture to form a second mixture, and coating the second mixture on a mild steel substrate and curing to form the submicron-/nano-jutecarbon/epoxy composite anti-corrosion coating.

Abstract: A cementitious blend composition and a concrete mix composition preferable for making concrete resistant to high temperatures and alkaline conditions, particularly for making durable concrete for constructing an alumina digester tank in an aluminum smelter. The cementitious blend composition includes at least one hydraulic cement, silica fume (SF), and natural pozzolan (NP), wherein a weight percent ratio of at least one hydraulic cement:SF:NP in the cementitious blend composition lies in the range of (24-63):(5-44):(32-40) with the sum of the weight percentages of the at least one hydraulic cement, the SF, and the NP not exceeding 100%. The concrete mix composition comprises water and the cementitious blend composition, wherein a weight ratio of the water to the cementitious blend composition is 0.2-0.5, and wherein the concrete mix composition has a content of the cementitious blend composition of 400-550 kg/m3.

Abstract: Oil ash comprising carbon in an amount in the range of 60% to 89% is an effective set retarder in a cement composition. The oil ash prolonged the initial and final setting time of cement paste and retained the slump flow in concrete for a longer time than concrete without the retarder. Also, the addition of oil ash to cement marginally improved the compressive strength of concrete. The advantage of oil ash is that it can be used as a solid retarder of cement hydration to substitute for the conventional commercial retarding admixtures with a limited shelf-life.

Abstract: A method of making a structural lightweight and thermal insulating concrete is described. The concrete has a coarse aggregate partly replaced by recycled plastic pieces. This enables the concrete to maintain a high compressive strength, low thermal conductivity, and low weight, while providing a use for waste plastic. The waste plastic pieces may comprise polyethylene in the form of flakes, fibers, or granules. Due to its low unit weight, adequate compressive strength and high thermal resistance the developed concrete can be used as a structural lightweight and thermal insulating concrete. The use of this concrete leads to economic and environmental benefits.

Abstract: Concrete compositions containing cement, a fine aggregate such as sand, a coarse aggregate such as crushed limestone, an industrial waste material such as electric arc furnace dust, cement kiln dust, oil ash, or limestone powder. High performance concretes made therefrom and methods of producing such concretes are also specified. The addition of industrial waste materials and nano silica provides enhanced mechanical strength (e.g. compressive strength, flexural strength) and improved durability (e.g. resistance to penetration of chloride ions) to the high performance concretes.
