Kajian Perilaku Geser Balok Beton Ringan Busa Dengan Penambahan Agregat Pasir Pozzolan

The four pieces of lightweight foam concrete beam with the sizes of 15 x 30 x 220 cm and planned for slide failure were tested in this study. The examined variables are the stirrup distance variations, ie; 20 cm, 25 cm and without stirrups. As a comparison, the similar reinforncemet beam with normal concrete were also prepared. Threaded Reinforcement used both on the main reinforcement and stirrups.In related with the quality of molten steel, the value of 415 Mpa was use for main reinforcement and 359 Mpa for stirrup reinforcement. Pozzolan sand used in this study brought from Krueng Raya at subdistrict of Mesjid Raya. Pozzolan sand aggregate used were those who passes the #4.76 mm strainer. The test results then compared with conventional concrete beam. The result show the values of slide beam capasity on various stirrups distance amounted to 71.5615 kN for 20 cm distance, 63.4626 kN for 25 cm distance and 31.0673 kN for foamed concrete beams without stirrups. As for the conventional concrete beams with 25 cm distance stirrup the value of sliding capacity equal with 74.2019 kN.
