Concrete density estimation by rebound hammer method [PDF]
AIP Conference Proceedings, 2016 Concrete is the most common and cheap material for radiation shielding. Compressive strength is the main parameter checked for determining concrete quality. However, for shielding purposes density is the parameter that needs to be considered. X- and -gamma radiations are effectively absorbed by a material with high atomic number and high density such ...
