| description | Rice Husk has been utilized as a mineral admixture, cement replacement option, and filler in cement concrete as it provides
several advantages such as improved strength values and environmental benefits related to the disposal of waste materials
and to reduce the carbon dioxide emissions resulting from production of cement worldwide. In this study, flexural behavior
of reinforced concrete beams using rice husk ash as a partial replacement of fine aggregates is investigated. For this
purpose, four types of concrete mixtures were produced using rice husk ash as a partial replacement of fine aggregates at
replacement levels of 0%, 10%, 15% and 20%. The produced reinforced rice husk ash concrete prism specimens were cured
in water and tested to determine the ultimate load and ultimate deflection at 28 days of curing. The test results depicted that,
the maximum ultimate load carried by reinforced rice husk ash concrete beam is 39.4 KN with 10% rice husk ash at 28 days
and minimum ultimate load is 19.02 KN with 20% rice husk ash used as a partial substitute of fine aggregates at 28 days.
The minimum ultimate deflection of 0.97mm occurred with 10% rice husk ash as a partial replacement of fine aggregate at
28 days of curing. Hence, this study concludes that 10% RHA can be utilized as a partial replacement of fine aggregates to
provide strength in concrete and to reduce the environmental burden of rice husk waste. The results of this study will also
provide a way forward to address the recent issues in construction sector, such as depletion of raw materials and increasing
cost of construction. |
