Concrete compaction significantly influences the strength, durability, and overall performance of concrete by reducing air voids and improving density. This study evaluated the effect of manual tamping and mechanical vibration on the compressive strength of M25, M30, and M35 concrete grades using 150 mm × 150 mm × 150 mm cube specimens designed according to IS 10262:2019. Specimens were compacted using 15, 25, and 35 tamping’s per layer or mechanical vibration for 15 seconds per layer, cured for 28 days, and tested using a Compression Testing Machine (CTM). Results showed that for M25 concrete, 25 tamping’s achieved the highest manual compressive strength (41.48 MPa), while mechanical vibration produced superior strengths for M30 (41.92 MPa) and M35 (46.37 MPa). Overall, moderate manual tamping provided satisfactory compaction, but mechanical vibration consistently reduced air voids and achieved higher compressive strength, particularly for higher-grade concrete, highlighting the importance of proper compaction in ensuring optimum concrete performance.
