Abstract

AbstrakPenelitian ini bertujuan untuk mengetahui durabilitas blok beton sandwich dengan isian styrofoam yang terhadapa lingkungan agresif yang dimodelkan dengan media perendaman. Media yang digunakan dalam penelitian ini adalah air tawar, air laut, air payau, dan air “rob” (air pasang yang masuk ke daratan). Perendaman benda uji dilakukan selama 28 hari. Proses perendaman dilanjutkan dengan pengujian kuat tekan. Hasil penelitian menunjukkan bahwa kuat tekan maksimal adalah sebesar 1,76 MPa pada media perendaman air rob, diikuti 1,67 MPa pada media perendaman air payau, kuat tekan yang lebih rendah diperoleh pada media perendaman air laut dengan sebesar 1,64 MPa dan kuat tekan terendah sebesar 1,36 MPa pada media perendaman air tawar. Kata kunci: durabilitas, blok, beton sandwich, styrofoam, kuat tekan, lingkungan agresif AbstractThe research aimed to observe durability of sandwich concrete block with styrofoam in aggressive environment which was modeled by curing media. The curing media used in this research are plain water, sea water, brakish water, and tidal flooding water. The curing was conducted for 28 days and followed by compressive strength test. The result of this research found that maximum compressive strength was 1,76 MPa with tidal flooding water as curing media, followed by 1,67 MPa with brakish water as curing media, and also 1,64 MPa with sea water as as curing media, and the lowest compressive strength was 1,36 MPa with plain water as as curing media. Keywords: durability, block, sandwich concrete, styrofoam, compressive strength, aggressive environment

Abstract

Shringkage is a volume change unrelated to the load, where the volume of concrete is reduceddue to reduced water content due to hydration or evaporation or evaporation. The objective ofthis research is to obtain the shrink parameter on sandwich block with Styrofoam stuffing inthe form of visual, damage, saturated and shrinkage in the medium of marine and freshwatersoak for 28 days and get the graph between time and depreciation. This research uses twoexperimental method that is by way of oven and not dioven in fresh water and marine waterimmersion media, each of which is submerged media in the form of 5 pieces of specimen length37 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 thecontainer 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 concretethen if it gets the result will result in the amount of shrinkage. The results obtained from theshrinkage will be concluded whether the sandwich panel with Styrofoam stuffing can be usedas a bearing wall.
