| Summary, etc. |
This study explores using Narra seed pod waste as an additive in producing concrete paving<br/>blocks, aiming to assess its potential to improve the strength and durability of concrete<br/>paving blocks (CPB). This study is focused on designing, fabricating, testing, and<br/>evaluating the effects of incorporating Narra seed pod ash (NSPA) in concrete paving<br/>blocks. Different mix designs using a ratio of 1:6, with various proportions of 0%, 30%,<br/>40%, 50%, and 60% NSPA, were incorporated into the concrete mix within the class B<br/>mixture. The physical and mechanical properties of each CPB sample were tested based on<br/>the ASTM standard requirement. The results in the water absorption tests show that 28-<br/>day-cured CPB with 40% NSPA had the highest water absorption rate of 2.77, which<br/>conformed with the ASTM C14O as it does not exceed 5%. CPB's compressive strength<br/>test results show that 40%, 50%, and 60% NSPA surpassed the ASTM C936M standard<br/>requirement with 3070 psi, 3133 psi, and 3295 psi. Flexural strength test results show that<br/>60% NSPA had the highest flexural strength of 689 psi, which met ASTM C78 standards.<br/>It indicates that a higher proportion of NSPA in the concrete paving blocks enhances their<br/>ability to withstand compressive forces. Including NSPA has positively impacted concrete<br/>paving blocks' compressive strength. It proves that utilizing Narra seed pod ash as an<br/>admixture in concrete paving blocks is effective. |
