Study on Utilization of Lime Mud from Paper Industry as A Construction Material

Environmental pollution is a serious issue that has arisen as a result of fast industrialization, urbanisation, and an increase in people's living standards. As a result, efforts should be undertaken to reduce pollution caused by trash disposal by converting undesired wastes into raw materials that may be used for a variety of purposes. Lime mud is a waste product from the pulp and paper industry that has shown to be a viable alternative binder in construction projects. To determine the strength qualities of blended concrete, experiments were conducted. The lime mud was used in place of the cement in nominal mixes. The nominal mix considered for the experimental work was of M-10 grade and produced by replacing cement partially with lime mud. The total of three mix proportions was prepared with varying percentage of Cement. Cubes were casted for the replacement of lime mud with cement in the proportions of 10, 30 and 50 percent. Compression tests were performed at 7 and 28 days to determine the strength qualities of the concrete grade. The test findings showed that ordinary concrete may be made by substituting lime mud for cement up to a specified percentage. Then by using the same grade we also made bricks using the same arrangement of materials and their compressive strength at 7 and 28 days was tested out.
