Professor B V Venkatrama Reddy of the Indian Institute of Science, Bengaluru, has developed a technology for producing building enveloping bricks using construction and demolition waste (CDW). Reddy has technology for producing alkali-activated bricks and blocks by utilizing fly ash and furnace slag.
The team of researchers developed low embodied carbon bricks from construction and demolition waste (CDW) waste through an alkali activation process using fly ash and ground slag and characterizing the thermal, structural, and durability characteristics of Low-C bricks and their masonry.
After ascertaining the Physico-chemical and compaction characteristics of the CDW, the optimum mix ratios of the materials were obtained, and then the production process was evolved to produce low-C bricks. Based on the optimum binder proportions, the compressed bricks were manufactured. The bricks were examined for engineering characteristics.
The major beneficiary of this development undertaken by IISc Bangalore with funding from the Department of Science and Technology, Govt. of India under Clean Energy Research Initiative, is the construction industry in general and the building sector in particular. This technology will also mitigate the disposal problems associated with the C&D wastes.
“A start-up has been registered which will be functional within 6-9 months to manufacture low-C bricks and blocks with IISc technical help. The start-up unit will act as a technology dissemination unit through training, capacity building, and providing technical know-how for establishing such commercial units across India,” says Prof. B V Venkatarama Reddy, IISc Bangalore.
