Analysis of the Effect of Battery Powder as Cement Additive on the Mechanical Properties of Concrete

Disposable primary battery waste can be classified into the Hazardous and Toxic Materials (B3) category. So there is a need for innovation to deal with these problems. This research aims to determine the effect of adding battery powder on cement weight and what is the optimal percentage of battery powder on the mechanical properties of 25 MPa concrete with variations in battery powder of 0%, 1%, 3% and 5%. Mix Design planning refers to SNI Concrete Planning 03-2834-2000. The results of the research showed a consecutive increase in compressive strength for the 0% variation: 25,233 Mpa, 1%: 27,350 Mpa, 3%: 31,064 Mpa, and 5%: 33,193 Mpa, an increase in splitting tensile strength for the 0% variation: 2,145 Mpa, 1% : 2,545 Mpa, 3%: 3,017 Mpa, and 5%: 3,088 Mpa, and an increase in variation strength of 0%: 2,799 Mpa, 1%: 2,953 Mpa, 3%: 3,518 Mpa, and 5%: 3,826 Mpa in concrete. So it can be concluded that the optimum variation is found in the 5% battery powder variation
