A composite cementitious feedstock includes mineral rock agglutinates, super absorbent polymer (SAP) particles, cement particles, and a binder. Each of the agglutinates has irregular surface regions and cavities originating at the irregular surface regions. At least a portion of the SAP particles and cement particles are disposed on the irregular surface regions and in the cavities. The binder coheres the agglutinates, SAP particles, and cement particles.
