Use of Blast Furnace Slag (Iron Slag) in Paver Blocks

The research exploits blast furnace slag as a replacement of sand on the physic-mechanical properties of concrete. The main objective of this experiment is to study the use of by-products like blast furnace slag. In addition to it also helps in reducing the cost of manufacturing concrete. This will be beneficial, the use of this waste material will save the cost as well as it will protect the environment from the effects of more pollution. The recyclable blast furnace slag is replaced with sand with the mix ration of 1:1.3:2.6 the percentage replacements are (50%, 75%, and 100%). Compressive test is conducted in this experiment. The results of compression test shows improvement after the use of blast furnace slag as a replacement of sand in concrete mixture. And this is helping towards the sustainable development. The optimum results of 80mm paver blocks is In between 30% to 40% more after the use of Blast furnace slag.
