Tetrahydro-dibenzo[a,d][7]annulene-5,11-dihydrazone and Magnesium oxide Used to Control the Corrosion of Aluminium in Chloride ions Environment
Abstract: Chloride ions interact with aluminium in marine atmosphere to form corrosion cell. Due to this corrosion reaction occurs on their surface, aluminium is oxidized into Al3+. The corrosion reaction accelerates deterioration in metal and it produces galvanic, pitting, stress, crevice, intergranular corrosion. Chloride ions decrease internal and external strength of aluminium metal. It is a very important metal so used in different appliances for e.g. road, water, air transports, housing, …

Self-Curing of Concrete Incorporated with Polyethylene Glycol
Abstract: Concrete is a combined mixture of cement, aggregates and water with or without suitable admixtures. Curing is the process of sustaining the proper moisture content to stimulate optimum cement hydration immediately after placement and to achieve desirable strength and other properties. In conventional curing of concrete, this is achieved by external supply of water after mixing, placing and finishing of concrete. In practice, the conventional type of curing is very …
