摘要

Large quantities of carbon dust are produced from the burning of agricultural residue, leading to significant environmental and health concerns. This study investigates the potential application of carbon dust as a partial cement replacement in concrete, providing sustainable alternative. The specimens were cast using different percentages of carbon powder as a cement replacement (5, 10, and 15%) in three different grades of concrete (M20, M25, and M30). We performed both non-destructive tests (ultrasonic pulse velocity, rebound number, initial sorptivity coefficient, and Wenner resistivity) and destructive tests (compressive strength, split tensile strength, and static modulus) on each specimen type. We conducted these tests on 14, 28, and 90 days interval. This study discusses in-depth effect of using carbon powder on both mechanical and durability parameters in conventional concrete. The study later validates the finding with scanning electron microscopy (SEM) study. The study also focuses on the effect of using carbon powder on the Wenner resistivity values of concrete. The study also provides valuable relationship between destructive and non-destructive test parameters using neural networks. The effectiveness of using the initial sorptivity coefficient as an additional input parameter in different neural models has been described. This study will promote application of carbon dust (waste) as a cement replacement in concrete at optimum levels in Indian construction sector.
