High‐Speed Penetration Test and Numerical Simulation of Ceramic‐Reactive Powder Concrete Composite Target

Shock and Vibration, Volume 2022, Issue 1, 2022., 2022
To study the protective performance of ceramic materials against the high‐speed penetration of projectiles, seven ceramic‐reactive powder concrete (C‐RPC) composite targets were designed. Using a 100/30 mm two‐stage light‐gas gun, penetration tests were performed at 1.4–2.0 km/s.

A Review on the Application of Circulating Fluidized Bed Fly Ash in Building Materials

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
Circulating fluidized bed (CFB)‐based coal burning technology is a type of clean coal combustion technology. Owing to its characteristics of low temperature combustion and desulfurization in furnace, the CFB fly ash is quite different from ordinary fly ash. Based on the comprehensive understanding of physical and chemical characteristics of CFB fly ash,
