Engineering Properties of Concrete Based on GP-Grout with Steel Nails

Abstract:

Portland cement-based grouting compound is called GP-Grout employed to produce a sort concrete as a replacement from the weight of cement in mixes and strengthened with steel nails to enhance the mechanical properties. GP-Grout replaced cement by 25%, 50% and 75% while the steel nails as locally steel fibres were used with 0.25%, 0.5%, 1%, 2 % and 3% by volume of concrete. GP-Grout powder enhanced mechanical properties of ordinary concrete especially; the compressive strength by increasing from 34 to 70 MPa as well as other properties including tensile and flexural strength with clear improvement by adding the steel nails at a ratio of 3% by volume and the results were 5.67, 9.81 MPa respectively.
