Partial Replacement Coarse Aggregate by EPS
Now a day's concrete plays a major role in construction industry. Availability of construction material is less day by day. So we can introduce a new kind of material in construction industry to reduce the cost as well as user friendly material. The main objective of the project, by using the available waste material to introduced in concrete industry. Fully replacement of concrete is not possible, so we can made an attempt to develop partial replacement of concrete material. In the last few decades there has been rapid increase in the waste materials and by products. Some of the industrial by products like GGBS, fly ash, copper slag, steel slag, Expanded polystyrene (EPS) have been successfully replaced for cement and concrete in the construction industry. It reduces the consumption of natural resources. Steel slag is one of the materials that is considered as a by product (waste material) obtained during the matte smelting and refining of copper. It has the physical properties similar to the fine aggregate, so it can be used as a replacement for fine aggregate in concrete. Likewise replacement of coarse aggregate is done by some materials, which makes the concrete light weight. This work shows the results of an experimental study on various workability and durability tests on concrete containing Polystyrene as a replacement of coarse aggregate such as compressive test, split tensile test and flexural strength. For this research work M50 M60 grade are used and the tests are conducted for various proportions of Polystyrene with coarse aggregate 2.5% 5% 7.5% 10% 12.5% 15% 17.5% 20% 22.5% 25% The obtained results were compared with those of conventional concrete. Key Word: Lightweight concrete, Construction materials, concrete, Building materials, Low density concrete, Compressive Strength, Split Tensile and Flexural Strength.
