Primary and secondary data were used for this study. Samples from the laboratory experiment were obtained from quarry sites at Owerrinta and Umunneochi. Sieve analysis, Slump test and Cube (crushing strength) were performed using each of the samples. The study observed that the crushing strength and/or compressive strength of the samples at 7 day are between 20-29N/mm2'' with Umunneochi samples having the highest compressive strength of 31.70N/mm2. Thus, at 7 days, the two samples tested have attained the minimum strength of concrete (i.e. 13N/mm2''). For workability test, the GF study observed that the percentage of slump for the samples ranges from 21.5– 41%. For sieve analysis, the researchers observed that the samples were fairly graded. The percentage of the grains passing through 12mm diameters is between 64.3– 84.0%. The study ended with the following recommendations that coarse aggregate should be properly graded using machines rather than hand breaking. Also coarse aggregate should be properly washed before using them since most of them are coated with impurities and other clayey substances and mud which may interfere with the process of bonding. ...Preview Download Preview +Other Building Technology project topics and materials you might be interested in»Causes of project abandonment in building construction industry and remedial measures»Causes of construction project failures and abandonments in Nigeria»Safety procedures and accident prevention methods in construction sites»Control of Noise Pollution and Sound Insulation in Buildings ( A Case Study of a Broadcasting Studio)»The implication and benefit of the use of softwares in building project construction (case study of selected software and firm)»Maintenance and servicing problems of specialist works in building»The effect of quality control in the building construction process (a case study of Afikpo, Ebonyi state)»A study of prospects and problems of timber as external material in building production in hot climate region»The impact of budgeting and budgetary control in construction project delivery in Nigeria»Challenges of low-cost housing delivery in Nigeria (Case study of Imo state)»Use of formwork design and construction of high building»Project planning and programming as tools for effective project delivery»The use of building survey for maintenance of building in Nigeria ( A case study of one storey building at Owerri, Imo state)»Design and construction of office complex for school of environmental design technology»Effects of labour management in building construction site - case study of Owerri, Imo state
