Splitting Tensile and Flexural Strengths of Agbabu Bituminous Sand Concrete

Abstract: The findings of an experimental investigation into the splitting tensile and flexural strengths of plain concrete produced with Agbabu bituminous sand are presented in this work. Open excavation was used to obtain bituminous sand, which was then crushed with a scoop to sand sizes. A total of eighty-four specimens were cast and tested. The slump test and the compacting factor test were used to assess the concrete's fresh properties. The samples were cured for 7, 14, 21, 28, 56, 90, and 150 days, respectively, before the splitting tensile and flexural strength tests were conducted. According to the findings, bituminous sand concrete is placeable compared to the control. Additionally, the tests demonstrate that the samples' splitting tensile and flexural strengths rose as the curing age increased, albeit at varying rates, with the control concrete achieving the highest strength. The splitting tensile and flexural strength of bituminous sand concrete grew gradually in the early curing ages but dramatically in the later curing ages. Accordingly, bituminous sand concrete may be used for concrete structures that do not need to generate high early splitting tensile and flexural strength, according to the trial results. Additionally, simplified empirical models were put forth to accurately forecast the bituminous sand-containing concrete's splitting tensile and flexural strengths.
