Steel and Concrete Bond Stress: A contribution to the study of concrete with rubber addition

Resumo

The bond stress between concrete and steel is the essential condition to the good behaviour of reinforcement concrete structures. To preview the use of concrete with waste incorporation for structural aims the verification of its quality control of compression strength and bond is necessary. This paper presents the study results about the viability use of APULOT tests, that is a bond tests, to prevent the compression strength of concrete with rubber addition. The purpose of APULOT tests become study in many laboratories in France and Brazil, the purpose is to estimate the compression strength using the bond stress obtained in tests execute inside of building construction. Also the use of concrete with rubber addition to structural use has been made with safe because this kind of addition makes the concrete compression strength decrease. This work aims to contribute with standardization of APULOT tests, and also give conditions to use the concrete with rubber addition in structural elements with more safe.
