Mix design and properties of concrete made from PFA coarse aggregates and sand

摘要: Pulverised fuel ash (PFA) is the principal waste product obtained from coal burning power stations in generation of electricity. Vast volumes such PFA anticipated further next two decades would create serious disposal and environmental problems many countries. One effective method utilising these large to manufacture aggregates them for plain structural concrete. The paper presents extensive test data on mix design, strength elasticity properties concrete made coarse sand having 28 day strengths 20 60 N/mm2. A design chart given together with equations related elastic modulus. Stress-strain curves applications are also reported.
