This journal is designed to reflect current developments and advances being made in the general field of cement-concrete composites technology and in the production, use, and performance of cement-based construction materials.The word cement is interpreted in a wide sense, including not only Portland cement but also blended cements and other binding materials.

However, concrete can also absorb carbon dioxide and store it in a process commonly referred to as carbonation. This may be viewed simply as an additional, alternative loop of the complex carbon cycle. Carbon dioxide may be absorbed by concrete in its many forms such as buildings, bridges and pavements (Figures 1a, b and c).

May 18, 2020· Carbon Footprint Of Concrete & Cement. Concrete has a carbon footprint of about – CO2e: 150kg per tonne; The manufacture of cement produces about 0.9 pounds of CO2 for every pound of cement.
