Vaterite Synthesis via Portlandite Carbonation (Case No. 2022-182)

Summary UCLA researchers have developed a process to manufacture stable vaterite, a calcium carbonate polymorph, by carbonating portlandite under mild conditions and using stabilizers to prevent its conversion to more stable forms. The resulting material can be used as a cement replacement to help reduce embodied carbon in concrete systems. Background Ordinary...

Direct Brucite Carbonation for Cementation (Case No. 2022-181)

Summary UCLA researchers have developed a method for replacing a substantial portion of ordinary Portland cement (OPC) by using direct carbonation of brucite (Mg(OH)₂) in concrete mixtures, enabling lower-carbon concrete products produced under near-ambient conditions with cost-competitive engineering performance. Background Concrete production using...
