Indian Students Develop New Concrete Mixture

Using rice husk ash as an economical and eco-friendly technology, a couple of GITAM University's civil engineering students have developed a new concrete mixture which is less expensive, reduces emission of greenhouse gases and gives more carbon credits. Final year students Manideep Tummalapudi and Surya Veera Vasudeva Rao Relangi, working on the theme ‘use of rice husk ash (RHA) in concrete' found that cement could be partially replaced by the rice husk ash to achieve eco-friendly results. It has been found that RHA added to the concrete in a certain ratio would give compressive strength similar to that of normal concrete.
