Evaluación mecánica de concreto y de corrosión en mortero con partículas de neumático reciclado
Abstract
The feasibility of using scrap tire particles in the elaboration of concrete and mortar was investigated. To assess the mechanical properties of hardened concrete, tests evaluating of its density, modulus elasticity and compression strength were undertaken. To determine the workability of freshly made concrete, a slump test was also performed. Tests in which 5, 7.5 and 10% of sand were substituted by recycled tire particles were made. The likelihood of corrosion on the steel is determined, using the technique of corrosion potential. To test the velocity of corrosion was used the linear polarization resistance method (LPR method) was utilized under the same conditions as well as fabrication of concrete. It was observed that using 7.5% of recycled tire particles offers satisfactory results in structures of moderate strength and lighter weight located in environments with chlorides.
Keywords: Concrete, mortar, recycled tire, corrosion rate, and mechanical properties.
