Fly  ash  is  widely  used  as  concrete’s  builder  because  it  contains  quite high  silica  (SiO 2 ) approximately  58,20%.  Fly  ash  can  increase  concrete power  pressure  and  contains characteristic  like  cement.  Fly  ash  contains low  CaO  approximately  3,30%  so  it  needs  other material  to  increase CaO on  concrete.  CaO  found  on  karbit  waste  it  contained  CaO approximately 56,5%. Method of concrete making and technical feasibility test on this research use SNI standar (SNI 03-2834-2000). Environmental feasibility test use Toxicity Characteristic Leaching Procedur (TCLP) according PP No. 101 tahun 2014. The results of this research show that  the  use  of    karbit  waste  and fly  ash  can  increase  concrete  power  pressure  at  age  of immersion  28  days.  Concrete  power  pressure  with  25%  fly  ash  addition  and  carbide waste 2,5%;5%;10%; and 15% are 22,05 MPa, 19,43 MPa, 18,59 MPa, 16.09 MPa. Concrete power pressure increase 34,2%; 18,25%; dan 13,14%. Heavy metal concentration at concrete with fly ash 25% and carbide waste 2,5% ; 5%; 10% are below standard. The best composition is the mixing between 25% fly ash dan10% carbide waste  which has Concrete power pressure 18,59 MPa.
