PENGARUH VARIASI TEKANAN KEMPA TERHADAP SIFAT FISIK DAN MEKANIK BETON STYROFOAM DENGAN PROPORSI CAMPURAN 75% STYROFOAM : 25% SEMEN DAN PENAMBAHAN PASIR 5%

Concrete styrofoam is kind of concrete which has experienced by technological innovation. Styrofoam used as a substitute of aggregates and mixed in concrete mixing, so it can reduces the weight of the concrete itself also can produces a high compressive strength. Styrofoam materials commonly found in the environment because it doesn�t work anymore and it becomes difficult to recycle waste and biodegradable nature. Therefore, it�s necessary to create some researches related to styrofoam concrete that aim to determine the physical and mechanical properties of the concrete. This research uses styrofoam that has been planed, but also need an addition of 5% sand with pressure clamp method at 1, 1,5, 2 MPa and variations in water-cement ratio is 0,35, 0,
