The Effect Of Treatment Of Ordinary Portland Cement (OPC) With Nickel II Sulphate Hexahydrate On Splitting Tensile Strength Ofnormal Concrete:-

ABSTRACT A Study was conducted on the effect of treatment of ordinary Portland cement (OPC) with Nickel 11 Sulphate Hexahydrate on Splitting Tensile Strength of Normal Concrete. Concrete can also be called a common material which is used in the construction industry on a daily basis, its use spans from the most menial work or element to mega building and structures. The aim of this research is to investigate the effects of pretreatment of OPC with Nickel II Sulphate hexahydrate (NiSO.i(I hO)6) chemical activator on the performance ofconcrete. Study the optimum percentage ofNickeI(II)Sulphate Hexahydrate [NiSOis observed. The splitting tensile strength at the age of28 days ofNickel II Sulphate Hexahydrate concrete continuously increased with respect to conventional concrete and reached a maximum value of 3% replacement level for the normal grade of concrete. Among the modified concrete, Split Tensile Strength with 1% Nickel II Sulphate from 7th day to 28lh day of curing showed the highest increase rate. It was discovered that Nickel II Sulphate has good impact in improving the Split Tensile Strength.
