Can virtual power plants optimize energy distribution?
Unlike traditional power plants, which are typically characterized by large physical infrastructure such as coal trains, smokestacks, and turbines, virtual power plants (VPP) rely on decentralized energy resources. These resources include rooftop solar panels, electric vehicle chargers, and smart appliances, all of which are integrated into a system that operates without a central physical facility.…

Impact of bad formwork of concrete in its service life
Formwork plays a vital role in reinforced concrete (RC) design, providing support for the concrete until it gains adequate strength. Its complexity can range from simple cubic boxes to intricate spline surfaces. While formwork design is a specialized area of concrete engineering, this article focuses on how poor formwork affects the service life of RC…

Pull out test in concrete
The bond between concrete and steel is a crucial factor in structural integrity. As concrete ages, this bond often weakens. This article outlines the procedure for conducting a pull-out test to evaluate bond strength. In tests with plain rebars, the maximum load typically coincides with the moment of initial slip. In contrast, deformed bars can…

Bonding behaviour in ASR affected concrete
Alkali Silica Reaction (ASR) has been found to deteriorate the bond between steel and concrete. This article will discuss if this is true. What is Alkali Silica Reaction? The Alkali Silica Reaction (ASR) is a chemical reaction that occurs between alkaline substances in cement and reactive silica found in some aggregates used in concrete. When…
