Question

Make a concise comparison of building materials in brick, light concrete and natural stone related to carbon dioxide emissions at the material.

Not to long answer and plz don’t write for hand because I cant understand your handwriting :).

Answer 1

Brick:

Brick is of clay material, clay constitutes carbonaceous matter, it starts to burn out at about 200-350 °C to form hydrocarbons and a more carbonaceous residue. These carbonaceous residues further combusted to emit CO and CO₂. It generally emits 10-12 % of CO₂ of total flue gas.

Light concrete:

The emission of CO₂ is similar to that of brick, but the latest technology is used where many materials like fly ash are being used where the CO₂ is very less.

Natural stone:

Natural is considered as the greenest building material. The amount of CO₂ emitted is very less compared to the above two. Though few materials like limestone is a high CO₂ emitter.

As a conclusion, CO₂ emission rates are in the order natural stone > light concrete > Brick
