It saves 25 per cent of the estimated cost

Manufacturing of clay bricks in Gulbarga hit owing to unavailability of water

40 lakh solid fly-ash bricks were prepared at the construction site itself

Raichur: The Karnataka Housing Board (KHB) recently completed construction of 340 houses in Gulbarga city utilising solid bricks made of fly ash. Besides saving 25 per cent of the estimated cost, the board also completed the project on time.

Utilisation of fly-ash solid bricks for construction was mooted in KHB when the contractor for the Gulbarga housing project expressed his inability to collect the required quantity of burn clay bricks.

According to Srinivas Kulkarni, executive officer at the Centre for Ash Utilisation Technology Environmental Conservation, Shakthinagar, the project contractor needed about 55 lakh clay bricks to build a cluster of 340 houses.

After work on the project had been completed till the plinth level, the contractor told the KHB that he would not be able to complete the project on schedule as he faced shortage of clay bricks. Manufacturing of clay bricks in the district had been hit owing to unavailability of water. Mr. Kulakrni told The Hindu on Tuesday that he thought of supplying fly ash solid bricks to the contractor when KHB told him about the shortage in supply of clay bricks. After completing formalities, he managed to manufacture the required quantity of solid fly-ash bricks at the construction site itself. He said it was for first time in the country that a housing project was completed utilising 40 lakh fly ash bricks. The Rajiv Gandhi Rural Housing Corporation had also been using fly-ash bricks in construction. However, it had not yet taken up any project exclusively utilising fly ash bricks, he said. Mr. Kulakrni said that using fly ash in building materials such as bricks, and hollow and solid blocks would not only be cost effective but also help in timely completion of projects. Besides, large scale utilisation of fly ash would help check environmental pollution from thermal plants.
