Abstract
This paper describes the experimental study of High-Performance concrete with quarry dust as fine aggregate in addition of steel fibre. To over-come the difficulties due to excessive sand mining, quarry dust was used as fine aggregate. Quarry dust is the fine material, produced from gravel crushers. Super plasticizers were used to improve workability of concrete. Cement was replaced with 10% of silica fume. The M60 grade concrete used was designed by using a modified ACI method suggested by Aïtcin. Volume fraction of the fibres used in this study as 0%, 0.5%, 1%, 1.5%. Specimens were casted and compression, split tensile and flexure test were conducted for 7 and 28days. Durability tests such as rapid chloride penetration test, Acid attack, sulphate attack, alkaline attack was also conducted. From the result it was found that addition of silica fume will increase the compressive strength, steel fibre will increase the tensile strength. Addition of 1% steel fibre is found as optimum from the experimental results.
