Abstract

In this study different brands of Ordinary Portland Cement (OPC) produced and available in Khyber Pakhtoon Khwa, Pakistan have been studied for different chemical parameters and compared with British standard specifications. The amounts of chemical constituents like SiO 2 , Al 2 O 3 , Fe 2 O 3 , CaO, MgO, SO 3 , 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.

巴基斯坦开伯尔-普赫图恩普通硅酸盐水泥的化学分析与比较
在本研究中,研究了巴基斯坦开伯尔-普赫图恩省生产和销售的不同品牌普通波特兰水泥(OPC)的不同化学参数,并与英国标准规格进行了比较。根据英国标准(BS)的规定,测定了其化学成分sio2、al2o3、fe2o3、CaO、MgO、so3、不溶物(IR)、游离石灰(free lime)和燃失量(LOI)。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。关键词:普通硅酸盐水泥,化学成分,质量验证DOI = 10.3329/cerb.v14i1.4320化学工程研究通报14 (2010)45-49
