Abstract
This research project focuses on conducting a comparative analysis of Portland cement in southwestern Nigeria. The study aims to investigate and compare the quality, properties, and performance of different brands of Portland cement available in the region. The research will involve the collection of samples from various cement manufacturers in southwestern Nigeria, followed by a series of laboratory tests to assess parameters such as fineness, setting time, compressive strength, and chemical composition. The analysis will also include an examination of the manufacturing processes employed by the different cement companies to understand how these processes may impact the final product. By comparing the results of the laboratory tests and analyzing the manufacturing processes, the research aims to provide insights into the variations in quality and performance among the different brands of Portland cement in the region. Furthermore, the study will consider the implications of these variations in terms of construction practices and durability of concrete structures. Understanding the differences in quality and performance of Portland cement can help construction professionals, engineers, and policymakers make informed decisions regarding the selection of cement for various construction projects in southwestern Nigeria. The research will contribute to the existing body of knowledge on cement quality and performance in Nigeria, particularly in the southwestern region where rapid urbanization and infrastructure development are driving the demand for construction materials. By identifying the strengths and weaknesses of different brands of Portland cement, the study aims to provide valuable information that can support the improvement of construction practices and the durability of infrastructure in the region. Overall, this comparative analysis of Portland cement in southwestern Nigeria is essential for ensuring the quality and reliability of construction materials used in the region. The findings of this research can serve as a basis for future studies on cement quality, as well as inform industry stakeholders and policymakers on ways to enhance the performance and durability of concrete structures in Nigeria.
Thesis Overview

</p><div><p><strong>Introduction </strong>Ordinary Portland Cement (O. P. C): a substance which binds together the particles of aggregates (usually sand and gravel) to form a mass of high compressive strength concrete. It is a combination of limestone or chalk with clay mixed in a proportion depend on the type of cement desired. Portland cement is the most common type of cement generally used around the world because it is a basic ingredient of concrete, mortar, stucco e.t.c. if a fine powder is produced by grinding Portland cement clinker more than 90 %, a limited amount of calcium sulphate which shall consist at least two-thirds by mass of calcium silicates (3CaO.SiO2). The remainder consisting of aluminum and iron containing clinker phases and other compounds. The ratio of CaO to SiO2 shall not be less than 2.0. The magnesium oxide content (MgO) shall not exceed 5.0% by mass. Portland cement as the cement that only harden by reacting with water but also forms a water-resistant product. Produce by pulverizing clinker consisting one or more of the form of calcium silicates, usually containing one or more of the calcium sulphate (diameter 0.2 – 1.0 inch (5 – 25mm), the low cost and wide spread availability of the limestone, shales and other naturally occurring materials make Portland cement one of the lowest – cost materials widely use over the last century throughout the world.
