Abstract

COMPARATIVE STUDY OF STRENGTH OF CONCRETE MADE FROM FRESH AND SALT WATER

Umana Oto-Obong I.* and Captain Uranta Jonathan D.

ABSTRACT

Fresh water is any naturally occurring water such as Lakes, Rivers, Ponds etc that has no dissolved salt, whereas salt water (sea water) is also a naturally occurring water but contains large concentration of dissolved inorganic ions such as sodium, chloride, sulphate, magnesium etc. This paper aimed at comparing the strength of concrete made from both fresh and salt water. Slump and comparative strength tests were performed on concrete made for both water and their initial and final setting time were noted. The paper conclude that concrete made from salt water has higher comparative strength than concrete made from fresh water, but gradually decreases after 28 days. The paper recommends that test should be conducted to evaluate the salinity of water before it is used at any construction site.
