Abstract
Durability can be explained as the concrete ability to counteract the abrasion, chemical attack, weathering action or any other process of degradation. Durability also includes the effects of serviceability and quality of concrete when exposed to acid and sulphate attacks. Steel Slag powder as partial substitute for cement and ROBO sand as complete alternative for natural sand are combined mostly on basis of the criteria of durability properties and costing qualities. Not only these properties, pollution in environment can also be lowered upto some extent due to the fact that emission of unsafe gases like CO(carbon monoxide) & CO2(carbon dioxide) are limited. In this research paper our study is mostly limited to the evaluation and observation of changes in both weight reduction & compressive strength in 6 different mixes of concrete grade M30 namely CAC(Conventional Aggregate Concrete), concrete mix manufactured by altering 0%, 10%, 20%, 30%and 40% of cement with Steel Slag powder proportions and by using the substitute ROBO sand as fine aggregate in 100% proportions in all 5 subsituted samples. After the 28days curing done for specimen the adverse effect of 5% of HCL(Hydrochloric acid) and MgSO4(Magnesium Sulphate) with water content on these concrete cubes are observed and determined by immersing completely. These specimens(cubes) for 56 days & 90 days in these acidic solutions, the changes in properties in weight reduction & compressive strength was observed and upto a great extent. Finally, we can conclude that concretes made up of that ROBO sand and Steel Slag powder really got durable properties and good strength when compared with regular aggregate in extreme harm environment.
Keywords- Concrete, Steel Slag Powder, Durability of Concrete, Robo Sand, Compressive Strength, Durability Tests.
