The growth of the industrial and construction sectors continues to increase every year. In construction, the main material used is concrete. Concrete is composed of cement, aggregate and water. However, 8% of CO2 emissions in the world come from the cement manufacturing process. In the industrial sector, the paper industry is one of the industries that produces the most waste, around 48 tons of waste for every 100 tons of pulp produced. The main wastes of the paper industry include slaker grits, dregs, lime mud and fly ash. To address this problem, research has been conducted on modification of concrete mix materials by utilizing paper mill waste. Fly ash is used as a substitute for cement and grits is used as a substitute for fine aggregate. From the research, it was found that the density value decreased with increasing fly ash mixture and the compressive strength value of mortar with variations in the addition of 0%, 10%, 20%, 30%, 40% and 50% fly ash respectively were 7.42 MPa, 6.68 MPa, 6.18 MPa, 4.97 MPa, 3.93 MPa and 2.97 MPa. The decrease in density and compressive strength with increasing fly ash is due to the less adhesive power of waste compared to cement due to its lower CaO content. The value of compressive strength samples 1, 2 and 3 belong to the N type which can be used as load bearing walls and samples 4, 5 and 6 fall into type O which can be used as non-load bearing and decorative walls in accordance with SNI 03-6882-2014 standards. Key Words: compressive strength, fly ash, grits, mortar
