Abstract
Limiting greenhouse gas emissions is critical to mitigate climate change. The building industry can contribute through the use of lower-embodied energy building materials. Rammed earth materials stabilised with alternatives to cement have been developed using industrial by-products and activators, sodium hydroxide or hydrated lime, or with no activator. Strength and durability testing demonstrated that the materials are suitable for low-rise construction. Life cycle assessment showed that greenhouse gas emissions per vertical square metre of wall could be reduced by up to 73% when compared to conventional building materials. Government policy mandating use of such materials should follow.
