Is Cleaner Cement Production Possible?

World cement production is growing more rapidly than we thought it would just a few years ago. In 2012, researchers at Columbia University told us they expected production to reach between 3.7 billion and 4.4 billion tonnes by 2010. But with the figures for 2014 now available, we find that world production already totalled 4.3 billion tonnes. Read more

First BONE Structure Set in Saskatoon

The BONE Structure concept was inspired from a combination of LEGO and Meccano — pieces are simply snapped together. The construction includes a lightweight, recycled steel frame, which enables homeowners to have a reconfigurable open-space concept, without intermediate beams or load-bearing walls. Electrical, plumbing, heating and ventilation systems are connected thanks to precut openings acting as veritable “highways” within the structure, just like an airplane fuselage. Read more

How Slightly Better Concrete Could Save the Planet

Recent research suggests that when it comes to concrete, we can do better. Several universities and corporations have set up research partnerships to make concrete more sustainable. In 2014, engineers at the Massachusetts Institute of Technology reported that by tweaking the ratio of starting ingredients, they had created cement samples with twice the strength of standard Portland cement.
