Potential applications of phase change materials in concrete technology Dale

In internal curing, pre-wetted lightweight aggregates (LWA) serve as internal reservoirs to supply the extra water needed by the cementitious and pozzolanic components of the concrete during their hydration processes. Due to their porous nature and reasonably high absorption capacity, the LWA can also be filled with other materials, such as phase change materials (PCMs). In this paper, three po...

Ultrasonic Array Imaging Method for Concrete Materials

Because of the need of rapid detection of internal defects and embedded object in concrete structures, a ultrasonic detecting method with linear array transducers is presented here, which is the high-resolution and efficient imaging technique for concrete materials by combining with synthetic aperture focusing technique (SAFT). At first, simulation data of array detection are processed to be am...

Environmental-friendly durable concrete made with recycled materials for sustainable concrete construction

Concrete is one of the most widely used construction materials in the world. However, the production of portland cement, an essential constituent of concrete, leads to the release of significant amount of CO2, a greenhouse gas; one ton of portland cement clinker production is said to creates approximately one ton of CO2 and other greenhouse gases (GHGs). Environmental issues are playing an impo...
