Consider the following statements:

  1. Recently, scientists at the Indian Institute of Science (IISc) developed a technology to produce low-carbon bricks that can serve as energy efficient walling materials.
  2. The team developed low embodied carbon bricks from construction and demolition waste (CDW) through an alkali activation process using fly ash and ground slag and characterising the thermal, structural, and durability characteristics of Low-C bricks and their masonry.
  3. These bricks require high-temperature firing and also use high-energy materials such as Portland cement.
