Novel NUS technique strengthens building structures by mixing biochar from saw dust with cement

Researchers from the National University of Singapore (NUS) have found an innovative and environmental-friendly technique to enhance building structures. The new method, which incorporates biochar recycled from saw dust into cement, improves the strength and water tightness of mortar and concrete, and offers an alternative use to the large volume of wood waste produced in Singapore.
