System to strengthen building structures

System to strengthen building structures


By mixing biochar from saw dust with cement, concrete constructions can be made 20 percent stronger and 50 percent more watertight.

A research team led by Associate Professor Kua Harn Wei has developed the novel approach of using biochar made from recycled wood waste to enhance concrete structures.

Wood waste from furniture processing plants makes up a tremendous segment of waste produced in Singapore. In 2016 alone, in excess of 530,000 tons of wood waste was created, of which, a critical sum is as observed tidy. Rather than burning or arranging them in landfills, wood waste can be reused to make biochar, a permeable, carbon-rich material that assimilates and holds water well.

Scientists from the National University of Singapore (NUS) have discovered a creative and ecological cordial system to improve building structures. The new strategy, which consolidates biochar reused from saw tidy into bond, enhances the quality and water snugness of mortar and cement, and offers an elective use to the vast volume of wood waste delivered.

Biochar is largely employed in the agricultural industry as a soil amendment to improve crop yield. Scientists expanded the application of biochar by successfully using biochar recycled from sawdust to significantly improve the mechanical and permeability properties of concrete and mortar.
