Low-carbon bricks developed using C&D waste for energy-efficient walling envelopes
The Hindu
Scientists have developed a technology that addresses two important issues – conserving mined raw material resources and emission reduction.
Researchers have developed a technology to produce energy-efficient walling materials using construction and demolition (C&D) waste and alkali-activated binders, the Department of Science and Technology said on Thursday.
Called low-carbon bricks, they do not require high-temperature firing, and avoid the use of high-energy materials such as Portland cement. The technology will also solve the disposal problems associated with C&D waste mitigation.
Conventionally, building envelopes consist of masonry walls built with burnt clay bricks, concrete blocks, hollow clay blocks, fly ash bricks, lightweight blocks, and so on.

On December 7, 1909, Belgian-American chemist Leo Baekeland’s process patent for making Bakelite was granted, two years after he had figured it out. Bakelite is the first fully synthetic plastic and its invention marked the beginning of the Age of Plastics. A.S.Ganesh tells you more about Baekeland and his Bakelite…
