This is Concrete

Produced by the  Global Cement and Concrete Association, without a spoken word, a 2-minute 30-second video presents the story of concrete in our world and everyday lives. Concrete is more than a material. It's about life, building our past and the present, and moving towards a sustainable future. To learn more about the commitment of the Global Cement and Concrete Association (GCCA) to produce carbon-neutral concrete by 2050, please visit their website: GCCA.org.
