PENGARUH BAHAN TAMBAH SERBUK BATA DAN SERAT FIBER PADA SELF COMPACTING CONCRETE (SCC)

The aim of this research is to study concrete compressive strength of Self Compacting Cconcrete (SCC) at 1 day age with additional powder of brick and fiber waste as fine aggregate in concrete mixture. Another benefit of this research is to get information related to the addition of fiber in SCC concrete slump flow value. Trial mix method is used in making concrete mixture with basic of K350 normal concrete mixture. Three specimens were prepared for each mixture composition. The addition of brick powder and fiber waste to SCC concrete production can improve the flowability and workability of SCC concrete shown by increasing slump flow value. The addition of 2.78% brick powder and 0.07% fiber can increase slump flow from 120 mm to 670 mm. Slump flow will be reduced by 50% in addition of fiber waste from 0.07% to 0.55%. A 1-day concrete compressive strength with the addition of brick powder and fiber waste will also increase. The addition of 2.78% brick powder and 0.07% fiber can increase the compressive strength of 1 day old concrete from 5.43 MPa to 6.17 MPa. The compressive strength will be reduced by 11% in addition of fiber waste from 0.07% to 0.55%.
