Experimental Study on the Effect of Prismatic and Cylinder Specimen Shapes on Concrete Compressive Strength at Different Width-to-Height Ratios

Key Points

• This research investigates how different specimen shapes affect the compressive strength of concrete at varying width-to-height ratios.
• Experimental study comparing prismatic and cylindrical concrete specimens.
• Utilized curing conditions, including standard and field curing in winter and standard environments.
• Examined width-to-height ratios of 1.0, 1.5, and 2.0.
• Both specimen types showed similar compressive strengths, with differences within an average of 5%.
• Cylindrical specimens demonstrated slightly higher compressive strength than prismatic specimens, regardless of width-to-height ratio.
