Abstract
A composite cementitious feedstock comprises discrete elements. Each discrete element includes mineral rock agglutinates having irregular surface regions and cavities. Super absorbent polymer (SAP) particles and cement particles are disposed on the irregular surface regions and in the cavities. A binder coheres the agglutinates, SAP particles, and cement particles.

A composite cementitious feedstock comprising a plurality of discrete elements, wherein each discrete element from said plurality of discrete elements includes
- mineral rock agglutinates, each of said agglutinates having irregular surface regions and cavities originating at said irregular surface regions,
- super absorbent polymer (SAP) particles, wherein at least a portion of said SAP particles are disposed on said irregular surface regions and in said cavities,
- cement particles, wherein at least a portion of said cement particles are disposed on said irregular surface regions and in said cavities, and
- a binder for cohering said agglutinates, said SAP particles, and said cement particles.
A composite cementitious feedstock comprising a plurality of discrete elements, wherein each discrete element from said plurality of discrete elements includes
- mineral rock agglutinates having sizes ranging from 250 microns to 1000 microns, each of said agglutinates having irregular surface regions and cavities originating at said irregular surface regions,
- super absorbent polymer (SAP) particles having sizes ranging from 1 micron to 120 microns, wherein at least a portion of said SAP particles are disposed on said irregular surface regions and in said cavities,
- cement particles having sizes ranging from sub-micron to 100 microns, wherein at least a portion of said cement particles are disposed on said irregular surface regions and in said cavities, and
- a water soluble binder for uniting said agglutinates, said SAP particles, and said cement particles in said discrete element.
