‼️ Sand is the most-consumed natural resource besides water, and the problem lies in the type of sand we are using.
‼️Sand can be in everything from cement to concrete, structural foundations, and glass production. With surging demand worldwide for new homes, commercial premises, roads, and other infrastructure schemes, there is a shortage of sand for construction.
‼️Even though there is enough sand in the desert, the desert sand is currently mainly useless to us.
‼️ The overwhelming amount of the sand that we harvest goes to make concrete, and desert sand grains are the wrong shape for that purpose. Desert sand is round and eroded by the desert wind and can't lock together to form durable concrete.
We would have an inexhaustible resource available to mitigate global emissions: waste. But today, although some concrete is recycled, many tons lay unused in landfills. These resources are even more critical now, in a time of shortages and rising raw materials and energy prices.
The world won’t slow down production, and the only way to global improvements is through green and economically feasible technologies.
Architecture for the desert is inspired by nature, like in the images attached; why can't the solution to the sand shortage problem be inspired by bio-mimic nature?
❓What if round sand from the desert, shredded concrete waste, or a mix of both can be used to build more "environmental-friendly" concrete and save 80% of the Co2 Emissions?
