The Suitability of Partial Replacement of Cement with Rice Husk Ash and Bone Powder in Concrete Structures

Abstract

The mixture of Rice Husk Ash and Bone Powder were used as partial replacement for cement in concrete structures. In this paper, the replacement varied from 5% to 20% in a mix of 1:2:4. Cubes casted comprise the control and specimen samples with various test considered, and the results showed that workability were consistent within the described values for lightweight concrete. The compressive strength dropped with the mixed ash content, the value was found to be within the range acceptable for concrete; particularly light weight concrete. Substitution of the mixture should not be more than 10% for the best result in the concrete production for concrete structures. There is reduction in density of the concrete from 0 10% replacement of material, and an increase in 10% 20% which shows that the unit weight of concrete first reduced, which in turn leads to reduction in total self-weight of the structure.
