Work Topic

Cementitious materials currently being utilized for DFAB processes are inherently less ecological than standard concretes: processing demands matrix-rich materials, and robust material control demands, until now, high clinker contents. Addressing this requires 1) a larger maximum aggregate size and 2) incorporation of cement substitutions.
