Abstract

Objective: The entry of diverse cement brands into the Honduran market necessitates rigorous quality verification. This study evaluates and compares the mechanical performance of an Imported Cement (IC) from Asia versus two established brands produced locally: a Multinational Cement (MC) and a National Cement (NC). Methodology: The research followed ASTM C109 standards, fabricating 50 mm mortar cubes for each brand. Specimens were subjected to compressive strength tests at curing ages of 3, 7, and 28 days to determine the strength development curve. Results: Experimental data indicated that the IC achieved the highest average compressive strength of 1,998.00 psi at 28 days, surpassing the MC (1,648.73 psi) and the NC (1,704.17 psi). Conclusions: The comparative analysis demonstrates that the imported alternative exceeds the mechanical performance of local brands under the tested conditions, providing a technical baseline for cost-benefit decisions in local construction projects.
