Characterization of Bambara Nut Shell Ash (BNSA) in Concrete Production

نویسندگان

چکیده

The goal of achieving concrete with adequate durability properties in terms reduced susceptibility to alkali-silica and mechanical-strength behaviour has led several high-performance materials development. While the use Bambara nut shell ash is gaining acceptance various applications, mineralogical composition such by-product cannot be easily controlled as a manufactured pozzolan. In this research work, characterization BNSA production was investigated. A mix proportion 1:3:6 water cement ratio 0.55 were used. percentage replacement from 0-40%. Concrete cubes 150mm × OPC/BNSA cast cured at 3, 7, 28, 60 90 days respectively. At end each period hydration, three replicate samples for hydration crushed their average comprehensive strength recorded. result compressive test indicated rise difference increases 5% 40% value 20.69% 46.53% density response showed slight increment 0.85% 3.47% Poisson results obtained indicates increase 5.17% 11.14% Furthermore, young’s modulus elasticity 9.4% 14.17% 10.81% 29.412% indicate satisfactory performance replacement.

The Use of Palm Kernel Shell and Ash for Concrete Production

Abstract—This work reports the potential of using Palm Kernel (PK) ash and shell as a partial substitute for Portland Cement (PC) and coarse aggregate in the development of mortar and concrete. PK ash and shell are agro-waste materials from palm oil mills, the disposal of PK ash and shell is an environmental problem of concern. The PK ash has pozzolanic properties that enables it as a partial r...
