In the 19th Century concrete was used mainly for industrial buildings. The first widespread use of Portland cement in home construction was in England and France between 1850 and 1880 by Francois Coignet, who added steel rods to prevent exterior walls from spreading. Ottawa-based company, Giatec Scientific Inc., is revolutionizing the ...

This seems to be primarily related to the emission-intensive production of cement, but a closer look reveals that the main contribution to CO 2 emissions is caused by the inefficient use of the materials steel and concrete. Instead of thin-walled shell structures, thick-walled concrete components subjected to flexural stress dominate today's ...

3) Self Compacting Concrete: Labor cost is a major concern for construction companies. This is the reason why self-compacting concrete is most preferred. When regular or high strength concrete is used in construction, it needs vibration to remove air in the mixture. This can be time-consuming, thus increasing labor cost as workers need to make sure that those air bubbles are not …
