Project description
Cement manufacture plays a major role in global CO2 emissions accounting for 5-8% of anthropogenic emissions. Magnesium-carbonate cements are studied as a carbon-negative option to the current paradigm. The global feedstocks of magnesium-silicate minerals are sufficient to capture all anthropogenic CO2 emissions for the foreseeable future. However a major bottleneck is the low reactivity of the raw materials, magnesium-silicates. To tackle this problem, highly-reactive magnesium-silicate glass will be synthesized that will react in the presence of water and minor activators, and is able to form carbon-binding phases. The work conducted in CEMGLASS aims to observe the basic phenomena that can be exploited in CO2-utilizing cements and assess its initial feasibility in large scale applications. If the nanostructured glass concept is successful, it would have massive carbon capture potential, due to large volumes of cement used every year.
