This article presents the results of experimental investigations on the size effect and the flexural behavior of full size reinforced concrete beams with lightweight aggregate and normal aggregate. The lightweight aggregate (LWA) was manufactured with fine sediments collected from the Shih-Men Reservoir in Taiwan. A total of 6 flexure beams with various reinforcement ratios (from 0.33% to 1.3%) and 6 size-effect beams with various dimensions were fabricated and tested. The designed compressive strength of concrete was 34 MPa. Test results indicated that the reinforced lightweight aggregate concrete (LWAC) beams had a similar load capacity and failure mode as those of …
