Effect Of Nickel (II) Sulfate Hexahydrate On The Durability Properties Of Concrete In Salty And Alkaline Environment:- Igboanugo Ikechukwu E

ABSTRACT

This study presents the results ofinvestigation ofthe effect of nickel(ii)sulfate hexahydrate on the durability properties of concrete in salty and alkaline environment. A concrete mix of 1:2:4 regimes ° (cement:sand:gravel) with water content. The highest weight of concrete at 0% Nickel(II)sulfate (NiSCH) is given as 7.55kg, at 1% is given as 7.79kg, at 3% Nickel(II)sulfate (NiSCU) is given as 7.85kg and at 6% NickeI(II)sulfate (NiSCU) is given as 7.89kg, therforen the weight of concrete increasead as the percentage of Nickel(II)sulfate (NiSCU) increased which shows that modification of concrete with NiSO4 can improve the durability of concrete in alkaline and salty environment Submerging the concrete in alkaline and salty environment also caused an increase in the length and width of the concrete which shows that NiSO4 ability to react with calcium hydroxide helps to strengthen concrete and can also reduce the permeability and porosity of concrete, hence, unwanted substances will be reduced in finding their way into tire concrete matrix.
