Type: article

Abstract: Ordinary Portland Cement (OPC) is a fundamental component in concrete production, influencing the performance and durability of structures. The various properties are essential for engineers, contractors, and construction professionals in selecting the most suitable OPC for specific applications, ensuring optimal performance and longevity of concrete structures. Therefore, the objective of this research was to assess how variations in chemical composition and fineness of OPC cement can affect key properties such as compressive strength, setting time, workability, etc. In this study, the investigation focuses on assessing variations in different key attributes such as setting time, fineness, physio-mechanical and microstructural properties of mortar produced using 04 different kinds of OPC samples and compared with standards. Test results show that fineness (>2250 cm2/gm), consistency (25-27%), soundness (1-2 mm), and compressive strength (40-55 MPa at 28 days) were obtained. Most of the OPC samples met the criteria of IS 8112:2013. Microstructural analysis using SEM showed that C-S-H and Ca(OH)2 at 28 days curing period are majorly observed in cement mortar.
