Abstract
The rising need for concrete is directly tied to urban expansion and population increases. Cement, a crucial component in concrete manufacturing, is a momentous source of global carbon dioxide secretions. To promote more sustainable concrete solutions, the adoption of alternative materials to conventional cement is essential. One such material with great potential is rice husk ash (RHA), which has shown promise in producing environmentally friendly concrete. However, assessing the performance of RHA-based concrete through laboratory testing can be time-consuming and complex. Predictive models provide an efficient approach to estimating the properties of RHA concrete, streamlining the process. Modern engineering increasingly relies on computational tools to save time, reduce resource use, and lower the likelihood of errors in project outcomes. These tools allow for virtual simulations, detailed analyses, and project refinements before actual implementation. This research introduced computer programs based on second-degree techniques from Scheffe and Osadebe to predict the compressive strength, moduli of rupture and elasticity of RHA concrete. Statistical evaluations confirmed the accuracy of these programs, as predicted results closely aligned with experimental data. These findings highlight the feasibility of using RHA concrete in structural applications. The computational programs not only reduce the dependence on extensive physical testing but also enable faster and more precise evaluations. By facilitating broader adoption of RHA as a sustainable building material, this approach supports the transition to greener construction practices. Further advancements in these predictive tools will be crucial for enhancing the practical application of RHA concrete, opening pathways for continued innovation and implementation in sustainable construction.
