    Abstract: The Schmidt hammer and Ultrasonic pulse velocity are the main importance to testing hardened concrete structures after the concrete has gain the strengths, which checking is necessary weather the concrete structure is suitable for designed use. Broken concrete and re-sized output are called recycled aggregate concrete cluster (RACC) owing to mix of... Show More
