Abstract

World Resources Institute data shows that there will be a fresh water crisis in 2040 including Indonesia. Responding to the above, many studies have been carried out using seawater, one of which is on concrete. Several studies have shown that seawater does not reduce the quality of concrete, but provides a corrosion effect on reinforcement.In this study, sea water concrete slabs have been made using bamboo as a reinforcement that will not corrode due to seawater. For concrete mix design refers to SNI SNI 03-2834-2000 and for slab flexural strength refers to 03-2847-2002. Slab specimens with sea water concrete that have been made consist of Slab concrete of steel reinforcement (SCS), Slab concrete of bamboo reinforcement V type notch (SCBV)? and Slab concrete of bamboo reinforcement? U type notch (SCBU).The result of the compressive strength of sea water concrete can reach the compressive strength of the plan. Tensile strength of bamboo reaches 223.5MPaand approaching the tensile strength of steel reinforcement. The maximum load of SCBV and SCBU were decrease than theoretical analysis of0.14% and 21.51% respectively. Otherwise, the maximum load of SCS greater than theoretical analysis with a difference of 14.67%. The flexural strength of the concrete slab was not affected by sea water as in compressive strength of cylinder.Keywords: Bamboo reinforcement slab, Flexural strength, Seawater concrete

Abstract

Bengkalis government do project to build Liong river bridge with construction type is concrete arch bridge. But at relatively new service time, there was a big deflection in one of bridge segments. In this research will be design the bridge with steel arch bridge type. Bridge design using RSNI T-02-2005 about bridge load standard. For steel frame design refers to RSNI T-03-2005, and concrete structure design refers to RSNI T-12-2004. In piles calculation, using the Schmertmann method. The results of top structure design is top chord using WF.305.305.22.35, bottom chord WF. 305.305.39.63, diagonal chord WF.305.305.22.35, vertical hanger WF 203.203.10.17, wind bracing WF.203.203.8.12, truss bracing WF.203.203.8.12, girder using WF.400.200.8.13, cross girder WF.500.200.10.16, and the main girder using WF.500.200.10.16 profile. The results of bottom structure design is abutment width of 9,3 m and abutment length of 11 m. Using concrete piles with diameter of 50 cm, length 20 m and 28 point of stake. The largest deflection of bridge is 118,72 mm. This deflection is still safe because the value smaller than tolerance deflection L/240, which is 458,33 mm. The most compatible construction method for liong II river bridge is temporary coloumn method.

Abstract

Currently concrete technology continues to grow and continue to innovate one of them using fibers. Fiber concrete has advantages over non-fiber concrete, among others: strong against the effect of shrinkage, ability to reduce crack, fire resistance, etc.  In this study, concrete mix design using the procedures listed on SNI 03-2834-2000. The sample used is a cylinder with a height of 30 cm and a width of 15cm in diameter, which is used for compression and tensile testing, while the slab is 400cm x 100cm x 15cm. The fiber used is steel fiber (dramix), with the addition of 2/3 of the thickness of the slabs. The charging is done using a two-point loading. From the result of the research, it is found that the loading of non-fiber slab (0%) of the initial crack is the maximum crack that has passed the maximum crack allowed with a crack width of 1.3 mm with a loading of 1160 kg. The initial crack with the largest load is found on the 1% fiber mixed slab, with the initial crack also being a maximum crack of 0.5mm which also has exceeded the required maximum crack. In the 4% slab the initial crack of 0.1 mm is a minimal initial crack with a load greater than the load of a non-fiber (0%) slab by load1200 kg. While the maximum load on the maximum crack according to the applicable maximum crack conditions, on the 5% fiber mixed slab with a crack width of 0.32mm by loading 1250 kg .
