Study on partial replacement of groundnut shell ash with cement

Nadiminti Venkata Lakshmi, Polinati Satya Sagar



Concrete plays a prominent role in the construction industry. In the present scenario, there is a shortage of this material so there is a need to find alternatives to replace it in the concrete. In order to overcome this situation; many waste products which are available freely like a paper waste, red mud, rice husk and plastic waste can be used.  Among all of these, Ground nut shell ash is one of the good waste materials available from the oil industry. It can be used widely for the replacement of cement. The ground net shell contains CaO, SiO2, Al2O3, and Fe2O3. This experimental investigation was carried out to evaluate the strength of concrete, in which cement was replaced with ground nut shell ash for cubes, cylinders, and Prisms with different percentages which vary from 0% to 30% at an interval of 5% were performed. Concrete was batched by weight on adopting a ratio of 1:2:4 with water–cement ratio of 0.6. Concrete cubes of 150*150*150 mm in dimensions, cylinders of 150*300 mm in dimensions and 100*150 mm prisms are used. These Cubes, cylinders, and prisms were tested for 7, 14 and 28 days for compression, flexural and split tensile strengths. It is observed that 10% replacement of ground nut shell ash shown the highest strength values when compared with other percentages and for 15% replacement of ground nut shell ash the compressive and split tensile strength obtained the highest strength rather than other flexural strength.
