A Comparative Study: Effects of Fineness of Cement on Consistency and Compressive Strength of Different Branded Cement in Pakistan

Abstract

Cement is one of the key components of concrete, and the qualities of a particular type of cement will affect the attributes of concrete made with that cement. The influence of variations in cement brand attributes that are available in Pakistan is examined in this study. Poor cement choice may affect how long a concrete building project will last. Fineness, cement consistency, concrete compressive strength, and mortar cube strength all grow with cement fineness since they all have a positive relationship with each other. This study aimed to investigate a few particular mechanical and physical characteristics of eight cement brands used in Punjab, Pakistan. The brands of cement that were compared were Kohat, Askari, Bestway, Paidaar, DG, Pioneer, Flying, and Fauji cement. The testing was carried out in a lab and according to ASTM guidelines. In contrast, Kohat had 5.17%, Askari had 8.67%, Bestway had 3%, DG had 2.67, Flying had 9.67, and Fauji cement had 6.33%, with only Paidaar above the allowed limits. Kohat and Paidaar cement's typical consistency was 30%, DG cement was 26%, and Bestway cement was 26%; all of them fell within the range of (26%- 33%). The 28-day compressive strength test results for DG cement and Bestway cement were 7787.74 Psi and 7225.17 Psi, respectively. The strength of Pioneer and Flying cement was found to be lower than that of other cement brands. Except for DG and Bestway cement, all eight brands of cement are used for all structural elements. Bestway cement is much superior for high-rise structures and heavy structural members. Consequently, by comparing the trace element concentration of various brands of Portland cement in Pakistan, the study evaluates the impact of trace element content on cement quality and concrete strength.
