ABSTRACT : Progress of sciences, especially civil engineering, demands a better concrete technology. To minimize self-weight of concrete, I tried to replace coarse aggregate by styrofoam. The self-weight of structure highly affected a planning of structure, especially if earthquake effect is considered. When the self-weight of structure is lower, it will produce lower quake force. In this thesis, use of lower structure weight was precast wall panel. Test of flexural capacity was done to understand the amount of face load value and examination of precast wall panel weight with length of 3 m, width of 7.5 cm, and height of 25 cm and also examine ease to establish time and way to install field precast wall panel. Phases of tests covered: tests of compression strength of concrete cylinders, tests of tensile strength of steel bars, tests of bond strength, modulus of rupture, and flexural tests of precast wall panel. The precast wall panel test made test thing with length of 3 m, width of 7.5 cm, and height of 25 cm, using one reinforce for non deformed with diameter 5.14 mm at center. The precast wall panel was tested by net extend of 2800 mm from support of joint to joint by using static load. Results of test consisted of styrofoam weight as much as 0.0142 t/m3, specific gravity of light styrofoam concrete as much as 0.718 t/m3, modulus of elasticity as much as 339.897 MPa, the compression strength of concrete cylinders at 28 days old as much as 1.519 MPa, the yield stress of steel bars non deformed with diameter 5.14 mm as much as 379.246 MPa, bond strength for non deformed steel bars with diameter 5.14 mm as much as 2.824 MPa, modulus of rupture produced 0.623 MPa. Unfinished precast wall panel at 28 days old with vertical position produced ultimate load as much as 1110.013 N, ultimate deformation as much as 17.500 mm, ultimate flexural capacity as much as 911595.767 Nmm, and unfinished precast wall panel at 28 days old with horizontal position produced ultimate load as much as 404690 N, ultimate deformation as much as 50.00 mm, ultimate flexural capacity as much as 283283.000 Nmm. Comparison of flexural capacity for experiment and theory with vertical position as much as 104.717%, whereas flexural capacity comparison for experiment and theory with horizontal position as much as 120.206%. Precast wall panel could be lifted after 1 days old with vertical position, while horizontal position had failed due to self weight, but better for precast wall panel lifted after 7 days old due to better usable for vertical and horizontal position. Keywords: styrofoam, wall panel, amount of dimension, move force.
