Abstract

The scope of this research is to make hollow concrete using Nickel Slag and compare it with crushed stone aggregate. The purpose of this study was to determine the amount of workability, porosity, permeability, and tensile strength of porous concrete, and to determine the effect of the 05-10 and 10-20 grading of the aggregate on the tensile strength, porosity and permeability of porous concrete. This study used an experimental method using aggregates with uniform gradations. The aggregates used are nickel slag and crushed stone with uniform gradations of 05-10 and 10-20. The cement water factor (FAS) used in the mix design is 0.35 and the cavity in the concrete is 20%. Workability testing is carried out after the fresh concrete is finished. mixed with the composition according to the mix design. Tensile strength test, with the compressive strength machine method performed at the age of the concrete 3 and 7 days. From the analysis with qualitative methods, porous concrete containing nickel slag and crushed stone in gradations 5 - 10 and 10 - 20 obtained the highest compressive strength values in the nickel slag aggregate mixture 5-10 and 10-20 of10.70Average - average 10.51 MPa, Modulus of elasticity of6316.43 average 6054.68 MPa, and Poisson Ratio of 0.1651 Average 0.1598.
