Cement is a key component of concrete; its qualities impact the properties of concrete created using a particular type of cement. In Pakistan, cement brands are used for an enormous amount. As a result, the cement qualities must fulfill the standards defined by the rules. This research compares the chemical properties of Paidaar, Lucky, DG, Fauji, and Bestway cement brands. This research compares the chemical properties of Paidaar, Lucky, DG, Fauji, and Bestway cement brands. The chemical analysis of cement was used to compute the compound composition of C3S, C2S, C3A, and C4AF. It was discovered that the Al2O3 and SO3 levels in Paidaar and Fauji cement exceeded the specified limits. The presence of more SO3 causes sulphates in cement to expand. Furthermore, a study of four key components (C3S, C2S, C3A, and C4AF) revealed that Paidaar, Lucky, and Fauji cement have less C3S and more C2S, as a result, when compared to other cement brands, it has the lowest strength. When different brands' chemical compositions were compared, the Paidaar, Lucky, DG, Fauji, and Bestway cements fulfilled the standards' recommended ranges. To ensure the quality specified by the standards, Paidaar, Lucky, and Fauji cement require significant quality control during the manufacturing process. [ABSTRACT FROM AUTHOR]
