| Summary: | 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, 0,4
