Chemical Analysis of Ordinary Portland Cement of Bangladesh

Abstract

This study compares the quality of different brands of Ordinary Portland Cement (OPC) available in Bangladesh. The amounts of chemical constituents like SiO₂, Al₂O₃, Fe₂O₃, CaO, MgO, SO₃, insoluble residue (IR), free lime and loss on ignition (LOI) were determined in accordance with British Standard (BS) Specifications. All the results are presented to provide both quantitative and qualitative notion of several locally produced ordinary Compositions of most of this constituents as determined experimentally were within the range of the standard values. The possible reasons for variation in chemical compositions and their consequences have been discussed.

Keywords: Ordinary Portland Cement, Chemical Composition, Quality Verification.
