| dc.description.abstract | Concrete's compressive strength is vital for assessing its ability to withstand loads.
This study compares the compressive strength of concrete using cube and cylindrical
specimens to understand the reasons for observed variations.
Specimens were prepared with a target strength of 30 MPa at 28 days, using Ordinary
Portland Cement (OPC), river sand, and crushed granite. Cube (100 mm x 100 mm)
and cylinder (100 mm x 200 mm) specimens were cured for 7, 14, and 28 days, and
tested for compressive strength. The strength variation is due to differences in
specimen geometry, stress distribution, and failure modes. Cubes experience uniform
stress distribution, while cylinders show concentrated stress at the ends, leading to
lower strength.This study concludes that cubes provide higher compressive strength
than cylinders, with implications for concrete testing standards and quality control.
Further research on concrete grade, specimen size, and curing methods is
recommended. | en_US |
