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 …

Assessment of Chloride Content in Plaster in Residential Buildings
Abstract: This study investigated the impact of chloride on building as per the age. Concrete samples were collected from buildings of different ages to measure chloride concentration. Findings revealed that chloride content increased with building age, potentially leading to decreased strength and damage. The research identified a significant concern of chloride-induced corrosion in older buildings, as chloride concentration increased with building age. To enhance the durability and safety of aging structures, …
