Abstract
Compared to conventional concrete, lightweight aggregate concrete has numerous benefits. However, its strength and ductility are inferior to those of standard concrete. This study investigates the impact of concrete strength and FRP layers on the behavior of lightweight aggregate concrete confined with FRP. Eight lightweight aggregate concretes consisting of artificial lightweight aggregate were manufactured, covered with FRP, and then tested for failure. It is demonstrated that increasing the strength of concrete and the FRP layer increases the strength and ductility of lightweight aggregate concrete. This study improves the use of lightweight aggregate concrete in civil structures.
