Thesis Abstract

Abstract
This study focuses on conducting a quality control analysis of cements produced by Dangote Cement Plc, specifically at the Ibese Cement Plant in Lagos. The quality of cement is crucial in ensuring the durability and strength of concrete structures, making it essential for construction projects. The research aims to evaluate the quality control measures in place at the Ibese Cement Plant to maintain consistent and high-quality cement production. The research methodology includes a comprehensive review of the quality control processes utilized by Dangote Cement Plc at the Ibese Cement Plant. This involves examining the raw materials used in cement production, the manufacturing process, and the testing procedures employed to assess the quality of the final product. The study also involves analyzing the compliance of the cement produced at the plant with relevant industry standards and specifications. Data collection for the research includes both primary and secondary sources. Primary data is gathered through on-site visits to the Ibese Cement Plant to observe the production processes firsthand and conduct interviews with quality control personnel. Secondary data is collected from existing literature, reports, and industry publications related to cement quality control and standards. The findings of the study provide insights into the quality control practices at the Ibese Cement Plant and identify areas for improvement to enhance the overall quality of cement production. By evaluating the quality control measures in place, the research aims to contribute to the optimization of production processes and the assurance of consistent quality in Dangote Cement Plc's products. Overall, this research serves as a case study to assess the quality control analysis of cements at the Ibese Cement Plant of Dangote Cement Plc in Lagos. The study's findings are valuable for the cement industry, construction sector, and stakeholders involved in ensuring the quality and performance of cement-based infrastructure. The research outcomes can guide future initiatives to enhance quality control practices, maintain product standards, and support sustainable construction practices in Nigeria and beyond.

Thesis Overview

1.1. BACKGROUND OF THE STUDY
The history of cement production in Nigeria can be traced back to 1957. From the onset, about three cement plants were commissioned by the Northern, Eastern and Mid-Western regional governments. Later, other companies such as Ashaka Cement, Benue Cement Company (BCC), West African Portland Cement Company (WAPCO) and Cement Company of Northern Nigeria (CCNN) and a host of others were established. But today, there are many cement manufacturing companies/plants in Nigeria with plants located across country. Some of the notable companies include: West African Portland Cement Company Plc (WAPCO); Ashaka Cement Company Plc; Benue Cement Company Plc (BCC); Cement Company of Northern Nigeria Plc (CCNN); Dangote Industries plc; Nigerian Cement Company Limited; Edo Cement Company Limited; and a host of others. One major characteristic of the cement industry in Nigeria is the problem of demand vs. supply inequality and lack of quality which specifically has led to the collapse of several buildings resulting to loss of lives and properties (Adetokun 2010). Since inception, available supply has not been able to meet the ever growing demand for cement. Even in the 1980s, during the economic recession which witnessed a decline in the demand for cement, these supply gaps were still very much evident. The modest but continuous growth in the Nigerian economy is a prospect for cement plants to increase local production. The rise in the demand of cement has led to a significance decrease in the quality of cement produced today in other to meet up with this growing demand. Recent collapse of buildings in Nigeria maybe as a result of the incompetency of the contractors but can be majorly as a result of the quality of cement and other building materials used in the construction of these buildings. The rate of collapse of buildings in Nigeria has geometrically increased overtime leading to the loss of lives and valuables.
1.2. STATEMENT OF THE PROBLEM
The alarming rate of collapse of buildings and the lack of durable roads and bridges in Nigeria has been a major concern which has led us to basically discover the real cause behind this malady. Due to the ever increasing demand for cement in Nigeria, a lot has been said about the quality of cement in Nigeria, this is another major concern for this survey. Cement production companies need to be adequately monitored and advised on when to service their plants and the right quality level of cement production to forestall further disheartening events in Nigeria.
1.3. OBJECTIVES OF THE STUDY
Ø To ascertain the quality of cement produced in dangote cement plc.
Ø To know if the recent collapse of buildings is as a result of the quality of cement and other building materials used or as a result of the incompetency of contractors.
Ø To know if recent improvement can be made on the already existing cement quality.
Ø To know if the cement plant is in good working condition or not.
1.4. SIGNIFICANCE OF THE STUDY
A major significance of this study is to ascertain the causes of collapse of buildings and by extension proffer solutions to minimize its further occurrence which in turn protects the generality of Nigerians.
Another major significance of this survey is to determine the quality of cement produced by checking the working ability of cement plants with a view to advising cement production companies on the right time to service their plants to maintain a satisfactory quality level of cement produced.
1.5. SCOPE/LIMITATION OF THE STUDY
The scope of this survey is centered on the quality control analysis of cements in the ibese cement plant Lagos state.
A major limitation to this work is the inability in gaining access to the cement production plant at the ibese plant in Lagos state.
Another limitation is getting the answers of respondents in Lagos and workers in ibese cement plant Lagos on the causes of collapse of buildings in Nigeria.Quality Control Analysis
1.6. DEFINITION OF TERMS
Ø Cement: a grey powder made by burning clay and lime that sets hard when it is mixed with water.
Ø Power Plant: an engine or other apparatus which provides power for a machine, building, etc.
