| TITLE | Evaluation of River Otamiri in FUTO Community for Construction Works Suitability |
|---|---|
| ABSTRACT | In Civil Engineering profession, water is the most sought and used construction material after concrete and there is a general saying that water that is good for drinking (Potable water) is also good for concrete. Sometimes, due to scarcity of potable water on some Nigerian universities, such as Federal University of Technology, Owerri (FUTO), one can be tempted to look upon nearby river on campus for alternative source of water supply. This work is aimed at evaluating the suitability of FUTO Otamiri River for construction purposes. In order to achieve this objective, some quantities of water from FUTO River Otamiri and borehole were fetched and used to produce concrete cubes using the Handy Developed Empirical [HDE] Mix Design Ratios developed by Nwachukwu and others (2025b) in ten trial mixes BASED on conventional mix ratios of 1:2:4. Thereafter, the concrete produced from River Otamiri [ROC] and that produced from borehole water [BWC] were subjected to compressive strengths investigations. The compressive strength results show that the maximum compressive strength of ROC cubes and BWC cubes evaluated are 13.95 MPa and 27.99 MPa respectively for the 28th day result. Thus based on the minimum value specified by the American Concrete Institute (ACI), as 20 MPa for good concrete and minimum required value (of 30.75MPa) specified by ASTM C 469 and ASTM C 39 for high performance concrete, this means that water from FUTO River Otamiri is not that too suitable for construction work where good and high performance concrete is required without complete treatment. Therefore, there may be need for proper treatment of the Otamiri River situated in FUTO Community before it can be used for horizontal and vertical construction works. |
