Vijayawada sources have stated that in what could be an efficient way to provide cheap and durable road connectivity in rural areas, a city-based associate professor has come up with a workable research on the Roller-compacted concrete (RCC) called special concrete.



Meanwhile Samanasa Krishna Rao, recently awarded PhD in Civil Engineering with specialization of transportation engineering from the JNTU, Hyderabad, has made an experimental investigation that could solve the road network problems in the villages. The RCC, already popular in the U.S. and the European countries, is mostly used for the construction of huge structures and Mr. Krishna Rao’s research is focused on using it for roads in the rural areas.

Mr. Rao who teaches in the V.R. Siddhartha Engineering College, had said usage of the RCC would be useful for the capital Amaravati where a large road network was needed to connect villages and as part of building a new capital, the government is to establish road network investing crores on it. But the available technology of blacktop or Portland cement roads is costly.



Mr. Krishna Rao had said the usage of the RCC which could be formed after replacing 60% of the ordinary Portland cement concrete mixture with industrial fly ash and metal slag will help overcome various burdens. It will not only reduce the overall cost by 50% but also consumes the industrial waste which would otherwise be dumped in open places and pollute surrounding areas".
