Concrete is the most widely used material in the construction industry. The cement required in the concrete leaves enormous carbon which shows an alarming impact on the global environmental conditions. Hence, there is a requirement of some material which can be effective in supporting cement when added along with it shows similar characteristics. Ground granulated blast furnace slag (GGBS) is found to be one such material which has similar characteristics when mixed with cement. GGBS is a by-product of steel manufacturing industry which is disposed. Quarry dust is a waste from the stone…mehr

Concrete is the most widely used material in the construction industry. The cement required in the concrete leaves enormous carbon which shows an alarming impact on the global environmental conditions. Hence, there is a requirement of some material which can be effective in supporting cement when added along with it shows similar characteristics. Ground granulated blast furnace slag (GGBS) is found to be one such material which has similar characteristics when mixed with cement. GGBS is a by-product of steel manufacturing industry which is disposed. Quarry dust is a waste from the stone crushing unit. This quarry dust can be used as partial replacement for fine aggregates in concrete.The principle objective is to study the strength properties. Concrete cubes,cylinders and beams for M40 grade are prepared initially by replacing the sand with quarry dust by increasing proportions as 10%, 20%, 30% and so on until an optimum is obtained. After with the optimum percentage of fine aggregate, the cement is replaced with GGBS by 10%, 20%, 30%, and 40%.
