Nepal: Ashden Environment and the United Nations Science, Technology and Innovation Forum have awarded Build Up Nepal their respective highest awards for its low-cement disaster-resistant concrete blocks. The Nepal Time newspaper has reported that the blocks contain a mix of 10% cement, 40% clay and 50% sand, all sourced from near Build Up Nepal’s Mitra Marg, Patang plant. The company has supplied its unique building materials to projects in 300 different communities, including the construction of 4500 homes. It says that the blocks, reinforced with iron rods, have a greater earthquake resistance than concrete.
Build Up Nepal said, “Interlocking brick is a highly suitable construction technology in Nepal, reducing the cost of construction as well as the carbon footprint of building a house. With this technology Nepal's houses can be stronger, more affordable and its air cleaner.”
