Abstract

Concrete has sizab/e specific gravity(± 2.2 (ons nr), therefore recpiired by dimension or heavy duty sizable plan press to be ab/e to bate that stmcture charges is alone. With lighter specific gravity therefore even stmcture dimension gets to be minimized. there is material even applicable aggregate substitution to reduce concrete specijic gravity is by use ojstyrojoam. This research analyze about purpose impact styrojoam as substitution of ground aggregate (sand) t o down concrete specijic gravity. Fine aggregate volume that substituted by styrojoam as big as 25%, 50%. 75%, with thc aim to determine thc ejfect oj styrojoam on the compressive strength and density of concrete. In research a/so uses viscocrete sika-10 as an added ingredient of 1.8% by weight of cement. which aim s to increase the compressive strength o f concrete. Of research result. known that each sand substitution with styrojoam 25% of volumed total sands. therefore specific gravity of concrete decreased on average by 5- 6%o and concrete compressive strength decreased on average by 28-29%. Up t o 75% substitution of the total volume o f sand, specijic gravity oj concrete decreased by 19- 27%o and 67-70% of the compressive strength. Levels of substitution of sand with styrojoam optimum i s 25% with specific gravity of concrete of 2254 kg'nv and compressive strength (K) of 259.08 kg cm2 or compressive strength (fc) of 22 MPa, according oj SNI 03-2847-2002 which States that concrete of structures that withstand eartlupiakes not /ess than 20 MPa.
