Context: Scientists of the Indian Institute of Science developed a technology for producing alkali-activated bricks/blocks by utilizing fly ash and furnace slag.

  • The researchers developed low embodied carbon bricks from construction and demolition 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.
  • Conventionally, building envelopes consist of masonry walls built with burnt clay bricks, concrete blocks, hollow clay blocks, fly ash bricks and lightweight blocks

 

Advantages of low-C bricks

  • They do not require high-temperature firing and avoid the use of high-energy material such as Portland cement.
  • The technology will also solve the disposal problems associated with construction and demolition waste mitigation.
