Abstract

Never-ending process of research being done on concrete brings forth the wide variety of concrete that we can put into use today. However, people tend to lean towards items that are easily available, cheap and possessing quality at the same time. Fly ash is a waste product obtained from industries can be used instead of cement at certain levels could be beneficial as it helps in lessening the rate of environmental degradation. In this project, cement has been replaced by fly ash in certain levels such as 40% and 50% and fine aggregate has been replaced by quarry dust as 10% and 20%. Target strength of M30 has been achieved. The characteristic properties of the constituent materials are studied; compressive strength and split tensile strength tests results are reported. These specimens tested for 7, 28 and 56 days. From the results it is seen that in comparison with conventional concrete, the increase in the level of quarry dust resulted in a slight decrease in strength. In this study concrete with 50% fly ash replacement and 10% quarry dust replacement instead of cement and fine aggregate proves to be more beneficial as well as economical.
