Effect of Partial Replacement of Ordinary Portland Cement with Portland Slag Cement on the Tensile Strength of Concrete

Key Points

• To assess the impact of partially replacing ordinary Portland cement with Portland slag cement on concrete's tensile strength.
• Partial replacement of ordinary Portland cement with Portland slag cement in concrete was tested.
• Tensile strength measurements were conducted to evaluate performance differences.
• Statistical analyses were performed to determine significance of results.
• Concrete with 20% slag cement showed a tensile strength increase of 25% compared to standard mixtures (p<0.01).
• No significant differences were found in tensile strength with 10% slag cement (p=0.05).
• Optimal performance was recorded at 20% replacement, indicating a viable alternative to ordinary cement.
