Performance Assessment of Compressive Strength Property of Concrete Made with Hong Soybeans Hull Ash and Groundnuts Shell Ash in the Production of Ternary Concrete

Abstract

Rapid urbanization through infrastructural development has resulted in depletion of natural resources leading to effects of flooding, global warming with incidents of health issues. A more ecofriendly way to solve this problem is through the adoption, use and invention of more ecofriendly concrete composite. Therefore, this research investigated the effect of replacing blended mix of soyabeans hull ash (SBHA) and groundnuts shell ash (GSA) in concrete production. A total of 108 cubes of 100mm x 100mm x 150mm were cast. The study specifically determined the physical and chemical properties of Soybean hull ash and groundnut shell ash, setting time and the compressive behavior of the concrete cubes. 6 mixes were produced with identities T0, T10, T20, T30, T40 and T50, the cubes were cured in water at 7, 14, 28 56, 90 and 180 days. The result shows an increase in compressive strength with increase in days of hydration. On 28 days curing, the strength of the ternary composites cured in water were in the range of 83% to 87% strength of the control cubes. The compressive strengths of the ternary concrete at 28 days were T0: 25.5N/mm2, T10: 21.1N/mm2, T20: 22.2N/mm2, T30: 24.2N/mm2 , T40: 22.2N/mm2 and T50: 24.3N/mm2 indicating a slow level of formation of SiO2 at the early stage of curing however at a latter age of 56 days curing there was a rapid increment in the compressive strength with all the concrete cubes attaining higher strength than the control concrete cubes while T50 possessed the highest compressive strength of 27.5N/mm2. Therefore, this study recommends T50 composing of 80%OPC + 12.5 %SBHA + 7.5% GSA for use for structural elements in Hong, LGA Adamawa for construction purposes.
