dc.description.abstractDwellers along the coastline area of Lagos State, Nigeria, are exposed to abundant supply of the natural resources of Atlantic Ocean and Lagoon water and may not have the privilege of having potable drinking water at their disposal for producing concrete. This study evaluates the characteristics of concrete produced with Atlantic Ocean and Lagoon water. Concrete produced with Tap water (regarded as potable drinking water) serves as the control experiment. Compressive strength, Workability and Density, were used to evaluate the characteristics of concrete specimens. All the concrete samples have true slump with Lagoon water concrete having low workability and both Tap and Atlantic Ocean water concrete having medium workability. The concrete specimens produced with the three types of water fall into the category of normal weight concrete as their densities lie within the range of 2200 to 2600 kg/m3 specified. The 28th day compressive strength of concrete specimens produced with Atlantic Ocean, Tap and Lagoon water are 25.0 and 33.5 N/mm2, 17.9 and 28.6 N/mm2 as well as 15.1 and 19.4 N/mm2 for mix ratios 1:3:6 and 1:2:4, respectively. The very high compressive strength of concrete specimens produced with Atlantic Ocean water notwithstanding, the high chloride content in it is detrimental to its use where reinforced steel bars are required. It was concluded that Tap water should be used in mixing concrete where strength is of major concern and Lagoon water may be used for general concrete works where strength is of less importance such as in mass concrete, floor screed and mortar.en_US
