“…The test procedure for cement was conducted according to BS EN 197-1 [6] and NIS 446 [40]. The strength of cement cannot be de ned directly on the cement itself; instead, it is determined indirectly through the use of cement mortar cast in a 1:3 ratio on concrete cubes, which are then tested using a compressive testing Machine [41]. The 1:3 cement-sand mortar with the water content of 8% is mixed and moulded into a brisquestte in the mould of 50mm.…”

Some brands of cement are often neglected in preference to others due to the fact that certain brands are more susceptible to cracks than others and also because of differences in their setting times. Continuous monitoring of these brands of cement prevents negative consequences for concrete structures. This research aimed at assessing the physical, chemical, and mineralogical composition of selected brands of Portland Limestone Cement (PLC) on strength performance in compliance with local and international standards. Tests such as specific gravity, standard consistency, setting time, soundness, fineness, compressive strength, chemical oxide compositions, and mineralogical properties were carried out to determine their suitability criteria for construction purposes, ensuring minimum established standards are met. The results indicated that at 28th day, Dangote PLC yielded the highest compressive strength of 48.02 kN/mm2 while UniCem PLC yielded the least compressive strength of 43.17 kN/mm2. The study concluded that the choice of cement strength class for any construction type interdepends on the physical, chemical, and mineralogical compositions of the cement incorporated at the place of use. Also, the margin difference in the strength and compositions of these cement brands does not give a significant reason to impede the performance. As such, none of these brands of PLC has a predominant advantage over the other, primarily for construction purposes. The knowledge of the properties of PLC in concrete construction is imperative to helping engineers make informed decisions about which brand is required to be used in specific circumstances for area of optimal applications.

“…Cement is one of the building materials which is non-metallic substance in nature with hydraulic binding properties and usually applied as a bonding agent in building materials such as concrete and other masonry works in the execution of structures in infrastructural development globally and used in the construction industry over many decades [1]. It consists essentially of mixture of calcium silicates and smaller amounts of other minerals that reacts with water and causes it to set uniformly.…”

In Ghana, however, ordinary Portland-limestone cement in recent times continues to remain the alternative construction material compared to other brands. With the rising trend of infrastructural development in the country undertaken by individuals and real estate companies, there have been categories of different brands of cement alongside the existing brands being produced in Ghana. The usage of lowquality cement resulting in poor bonding of construction materials has led to the investigation of some selected brands. In this study six different brands of Portland - limestone cement generally used in the construction industry in Ghana, namely; CIMAF cement, Dangote cement, Diamond cement, Ghacem cement, Sol cement and Supacem cement were investigated. The chemical compositions were analyzed using X-Ray Fluorescence (XRF) spectrometer equipment because of its accuracy and simplicity it has over other technologies. The amount of chemical constituents like A2O3, SiO2, Fe2O3, CaO, MgO, SO3, Na2O and K2O were determined in accordance with ASTM C114-18. The results indicated that the properties of the six brands of cement are comparable and are all of good quality.

There is an on-going debate about the strength and durability of the different brands of cements used for construction in Ghana. This has raised doubts on the quality and performance of the strength of the different brands of cements. Concrete is a composite material made of aggregates such as sand and stone that are mixed uniformly in the required proportion together with water for it to achieve the desired strength in its development. Cement is an important ingredient that binds together other building materials by a combination of chemical processes known as setting. Among the various physical properties of cement, compressive strength is the most vital property which gives an overall assessment of quality of concrete as the strength of concrete shows the ability of the structure to withstand various loads during it lifelong performance after construction. This research investigated the compressive strength of six different brands of 32.5R and 42.5R cements used for construction works in Ghana, namely, CIMAF cement, DIAMOND cement, GHACEM cement, SOL cement, SUPACEM cement and DANGOTE cement. Among the 32.5R brands, GHACEM cement developed the highest 28th day compressive strength of 30.96 N/mm2 and CIMAF cement the lowest strength of 25.89 N/mm2. In the 42.5R group, DANGOTE had the highest 28th compressive strength of 37.19N/mm2 while SOL produced the lowest with 31.11N/mm2.
