Use of Waste Paper Pulp and Fly Ash by Partial Replacement of Cement in Concrete

The use of paper-mill pulp and fly ash in concrete formulations was investigated as an alternative to landfill disposal. The cement has been replaced by sludge and fly ash accordingly in the range of 5% to 20% by weight for M-20. By using adequate amount of the waste paper pulp, fly ash and water, concrete mixtures were produced and compared in terms of slump and strength with the conventional concrete. Development of concrete by using paper sludge and fly ash for building & construction works. The concrete specimens were tested in three series of test as compression test, splitting tensile test and flexural test. These tests were carried out to evaluate the mechanical properties for up to 28 days. As a result, the compressive, splitting tensile and flexural strength increased up to 15 % addition of waste paper pulp and fly ash then further increased in waste paper pulp and fly ash reduces the strengths gradually.
