  A Study on Effect of Partial Replacement of Cement by Cattle Bone Ash in Concrete Property
  Author(s): Shumet Getahun* and Bahiru Bewket
  
  The study was aiming to investigate the effect of partial replacement of cement by cattle bone ash (CBA) in a concrete property. Complete silicate analysis of CBA shows that the material has high calcium oxide content (43.26%) which is the major oxide compound of cement. A C-25 concrete grade was selected for this study. The Normal consistency, setting time, soundness of cement paste, slump, compressive strength and density of concrete tests are done with (0%), 5%, 10%, 15% and 20% cement replacement with cattle bone ash. The compressive strength of concrete was done by curing 15 cm × 15 cm × 15 cm cube concrete specimens underwater for 3,7,28 and 56 days. The normal consistency of the cement paste increases as the percentage of the cattle bone ash increases in the paste attributed to high water absorption of CBA than OPC. The initial and final sett..
