Evaluation of rubbercrete based on ultrasonic pulse velocity and rebound hammer tests

Construction and Building Materials, 2011
Abstract Several research works have been carried out to study the fresh and hardened properties of concrete containing crumb rubber (rubbercrete) as a replacement of fine aggregate. The outcomes of these studies have highlighted the advantages and disadvantages of rubbercrete compared with conventional concrete mixtures.

Strength Evaluation of In-Situ Concrete by Rebound Hammer and Core Testing

Cement, Concrete, and Aggregates, 1994
Abstract This paper describes the results of an extensive field investigation where the quality of in-place concrete flatwork was evaluated. Nondestructive testing (NDT) was carried out using ultrasonic pulse velocity and rebound hammer techniques to establish a correlation with compressive strengths of core tests.

Interaction of electrical resistivity with rebound hammer and ultrasonic velocity test

Los programas de inspección periódica de estructuras de hormigón armado son fundamentales para planificar el mantenimiento y para un mejor control del comportamiento estructural en condiciones de servicio. En este contexto, los ensayos no destructivos (END) son herramientas importantes destinadas a monitorear la integridad de las estructuras, ya que ...
