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.

孟加拉国普通硅酸盐水泥的化学分析
本研究比较了孟加拉国不同品牌普通波特兰水泥(OPC)的质量。根据英国标准(BS)规范测定了SiO2、Al2O3、Fe2O3、CaO、MgO、SO3、不溶物(IR)、游离石灰(游离石灰)和燃失量(LOI)等化学成分的含量。所有的结果都提供了定量和定性的概念,几种本地生产的普通组合物的大多数成分实验确定在标准值范围内。讨论了化学成分变化的可能原因及其后果。
