Abstract

See full text

A cementitious composite includes a first layer, a second layer, and a cementitious mixture disposed between the first layer and the second layer. The cementitious mixture includes (i) cementitious materials and (ii) a viscosity modifier and/or an accelerator. The cementitious materials provide a void fraction between 0.64 and 1.35. The void fraction is defined as the ratio of the volume of the voids within the cementitious mixture per unit area of the cementitious composite to the volume of the cementitious materials per unit area of the cementitious composite. The cementitious mixture is configured to absorb a mass of water that provides a maximum 28 day compressive strength of the cementitious composite. A ratio of the mass of the water relative to the mass of the cementitious materials of the cementitious mixture per unit area of the cementitious composite that provides the maximum 28 day compressive strength of the cementitious composite is between 0.25 and 0.55.
