Kinerja Susut Pada Blok Beton Sandwich Dengan Isian Styrofoam

Abstract

Shringkage is a volume change unrelated to the load, where the volume of concrete is reduced
due to reduced water content due to hydration or evaporation or evaporation. The objective of
this research is to obtain the shrink parameter on sandwich block with Styrofoam stuffing in
the form of visual, damage, saturated and shrinkage in the medium of marine and freshwater
soak for 28 days and get the graph between time and depreciation. This research uses two
experimental method that is by way of oven and not dioven in fresh water and marine water
immersion media, each of which is submerged media in the form of 5 pieces of specimen length
37 cm, width 15,5 cm, and thickness 7.5 cm which if in total amounted to 10 concrete blocks,
the concrete block is tested in laboratory materials Soegijapranata Unika by using the
container as a medium of immersion media and the length of the sorong as a tool length, width,
thickness of the block and the scale that has a precision of 0.1 for get the weight of the concrete
then if it gets the result will result in the amount of shrinkage. The results obtained from the
shrinkage will be concluded whether the sandwich panel with Styrofoam stuffing can be used
as a bearing wall.
