Compressive Test of Concrete With Teak Wood Attached Waste Iron Lathe as a Replacement of Coarse Aggregate

Abstract The research team thought about the sustainability of concrete material because the stone used every year will be exhausted for the next generation. Innovation material renewable, sustainable, and waste materials required. This is pre-research teak wood used as a mixture to reduce coarse aggregate stone, added containing lathe waste to give friction to the wood. Objective: find an alternative coarse aggregate, with renewable and sustainable materials. Experimental methods in laboratories with relatively high quality are widely used in construction projects in Indonesia.Standard quality plan of concrete fc29.05 MPa, variation t 1 coarse aggregate teak wood 10%, variation t 2 teak 9.5%, lathe waste 5%. Test results of standard concrete 28.87 MPa, 13.70 MPa Variation 1 drop 52.75.. % and 14.24 MPa variation 2 drops 49.18 % The failure of standard concrete experienced large cracks, while variations 1 and 2 were smaller, which means it is not brittle and light, which is advantageous in applying the concrete structure for buildings. The conclusion. alternative use of teak wood waste material, especially attached iron lathe filler waste, is very useful for the sustainability of the use of concrete. However, mixed concrete design requires a higher concrete quality to achieve applied concrete
