We have recently seen a number of innovations aimed at creating sustainable construction processes. For example, using graphene to strengthen concrete and dissolvable packaging for construction materials. Now, engineers have devised a more sustainable concrete. Portland cement is a vital component in concrete. Furthermore, it is used to bind the other components of concrete together. Yet, its production is a huge contributing factor to carbon dioxide in the atmosphere. Now, engineers at Rice University’s Multiscale Materials Lab have developed a concrete binder made of fly ash, that can replace Portland cement as a binder in concrete. Fly ash is a…
