Characterization of the Mechanical Properties of Fiber-Reinforced Lightweight Concrete

섬유보강 경량골재 콘크리트의 역학적 특성에 관한 실험적 연구

An experimental study is conducted to charaterize the mechanical properties of a fiber-reinforced, lightweight concrete (FRLAC) that is produced without an autoclave process. The FRLAC enhances the strength of lightweight cellular concrete by adding polypropylene fibers. A series of compressive strength tests on cylindrical specimens are carried out to characterize the compressive strength and the modulus of elasticity of the FRLAC. Specifically, various mixing rates of a foam agent are applied in casting of the specimens to investigate the influence of the mixing rate of the foam agent on the performance of the FRLAC and to determine the optimal mixing rate of the foam agent.
