| dc.description.abstract | There are significant environmental benefits of recycled aggregates prepared from demolished concrete and reusing it as coarse aggregates for structural concrete, but the use of recycled aggregates in concrete is yet limited. Fly ash is an industrial waste which can be used in concrete as a partial replacement of cement. Foundry sand is also an industrial waste which can be used to replace sand as fine aggregate in concrete. Thus, an experiment was conducted in the laboratory of the department of Civil Engineering, Punjab Agricultural University Ludhiana to investigate the Properties of concrete using recycled aggregates, foundry sand and fly ash. The experiment was performed to check the compressive strength and workability of M20 concrete. Cube samples 144 in nos. of size 150mm X 150mm X150mm were prepared by varying percentage of fly ash as part replacement of cement by 0%, 5%, 10% and 15% and varying percentage of foundry sand as part replacement of fine aggregates by 5%, 10% and 15%. Water-Cement ratio was kept constant at 0.5. Workability was tested at the time of casting of concrete samples. The results shows that there was an increase in the workability with the partial replacement of fine aggregates by foundry sand and partial replacement of cement by fly ash. The optimum value of compaction factor was at the replacement level of 10 % of fly ash of cement & replacement level of 5 % of foundry sand of fine aggregates. Curing was done for 3, 7, 14 & 28 days. Samples were tested for compressive strength after 3,7,14 and 28 days. The optimum value of compressive strength was achieved with replacement of 5% of cement by fly ash & 5% of fine aggregates by foundry sand. | en_US |
