Load cell set-up for indirect stress test
Abstract
The compressive strength of concrete mixtures is achieved by designing systems that meet the mechanical and durability properties established by national and international standards. In this work, a customized load actuator element is proposed in the generatrix, both in the upper and lower part of the cell, to have a better load distribution in the specimen and to exert a uniform support in the contact section for the indirect tensile test. In this project, a device was designed and manufactured that can serve as instrumentation for the Controls modC-43C04 brand press to serve specimens, in which the concrete is subjected to tensile stresses with greater intensity, where it is expected that the steel of reinforcement is the one who acts by absorbing these efforts. Through the mechanical tests, it was established that the cell complies with a functional design and with the needs of the press for which it was adapted.
