Abstract: India is facing problem of waste disposal from a hefty amount of time. The landfill situation is resulting in high disposal costs. In this research paper the study is to figure out the suitability of charcoal dust and paper pulp in replacement of sand and cement respectively in concrete by some percentage without affecting its properties. The concrete containing various mixes were prepared and strength parameters like slump test, split tensile strength, compressive strength were determined. Different mixes were prepared and replacement of concrete with waste paper pulp by 5% ,10%, 15 % and 5% of charcoal dust as a sand replacement is carried out in all the concrete samples. The laboratory experiments shown that replacement proportion of 10% of paper pulp and 5% of charcoal dust as a sand replacement is enhancing the compressive strength and split tensile strength of concrete. The slump value decreases on increasing the percentage of paper pulp in concrete but concrete can be made more workable by increasing the amount of water. The addition of more than 10% of waste paper pulp has reduced the strength of concrete.

Keywords: Charcoal dust; paper pulp; compressive strength; split tensile strength.
