Concrete in the news!!

Concrete is tipping us into climate catastrophe. It’s payback time

Cement, the key component of concrete and one of the most widely used manmade materials, is now the cornerstone of global construction. It has shaped the modern environment, but its production has a massive footprint that neither the industry nor governments have been willing to address….

Because of the heat needed to decompose rock and the natural chemical processes involved in making cement, every tonne made releases one tonne of C02, the main greenhouse warming gas.

Annual cement production has quadrupled from nearly one billion to over 4 billion tonnes a year in 30 years. In the next decade it is expected to increase a further 500m tonnes a year. Unless there is a dramatic change, cement emissions are expected to continue to rise beyond 2050.

The cement industry has transformed the world and enriched both itself and mankind. But it now threatens to tip the environment into uncontrolled warming. It’s now payback time and the industry must respond urgently to the problem it has helped to create.

Timber Engineering Morning Tea

Have you heard a wooden building creak and groan in an earthquake and wondered why the university is building a multistory wooden building ?

The Timber Engineering group at the University of Canterbury has an active research programme on using timber for multi-storey buildings Come along on Friday 28th September to hear more about  this timber research from the academic supervisor and three PhD students . Keep 10.00 to 11.00 aside for morning tea and the presentations. Morning tea will be supplied by the famous Darfield Bakery

Come along on Friday morning…  this Friday 

Have you looked up at the new timber building on campus and wondered how this is possible?
