The connection model of segmental precast concrete beam reinforced with recycled tyre

Abstract

Segmental precast reinforced concrete with waste tyre as reinforcement is one method of simplifying and speeding up the installation of on-site concrete structures. This study determines the connections between segmental precast reinforced concrete and waste tyre as reinforcement. The dimensions of the specimens used in the experiment are 15 cm × 15 cm × 50 cm. The size of recycled tyre as reinforcement used is 10 mm × 10 mm in cross section view. One specimen is concrete beams with waste-tyre reinforcement as a standard test specimen. Four other specimens are in the form of segmental precast concrete beams with segmental connector lengths of 10 cm, 15 cm, 20 cm, and 25 cm. Furthermore, concrete beam specimens are tested to investigate their flexural capacity with a three-point loading method. The results show that the length of the reinforcement fitting does not significantly affect the flexural strength of the beam. The flexural strength capacity of concrete beams reinforced with recycled tyre with these connectors is approximately 10 kN.
