In India, a considerable part of electricity is produced from thermal power shops. These thermal power shops use disparate types of energies for combustion. During combustion of coal as an energy in these thermal power shops, a by-product of videlicet fly ash is produced. Indian coal has loftiest ash content as compared to coal set up in other countries. There are nearly 85 thermal power shops in India which use coal as a source for power generation and therefore produce a large quantum of cover ash. This cover ash is disposed of in soil, which in turn causes a lot of environmental problems. To overcome this disposal of cover ash into the soil, it can be used in concrete by incompletely replacing it with cement. Because the chemical number of cover ash and cement is nearly identical.The main idea of this report is to assay the gesteof M20 grade concrete with blend design11.482.74 and with0.48 water cement rate. Then cement was incompletely replaced by 10, 20, 30 of cover ash of F- class by weight. As concrete shows cracks suddenly when witnessing pressure. So to overcome this challenge and to enhance the flexural potency of concrete, sword filaments were used. The sword fibres of hook type in chance of 0.5,1.5 were used to produce M20 grade concrete. Aspect ratio of the sword was 50. Compression strength test, flexural strength test, resolve tensile test were performed according to guidelines of Bureau of Indian norms. Due to extension of sword fiber and fly ash Compressive strength, flexural strength, resolve tensile strength has increased due to pozzolanic action of cover ash and strong bond conformation of sword fibre. The loftiest value of compressive strength and flexural strength was achieved, when cement was replaced by 10 of cover ash and with addition of1.5 of sword fibre. Split tensile strength achieves its loftiest value at 10 of fly ash and 1 of sword fibre. Due to addition of cover ash, plasticity starts adding
