Abstract
A cementitious composite includes a structure layer, cementitious material, a first layer, and a second layer. The structure layer defines a plurality of open spaces. The cementitious material is disposed within the plurality of open spaces of the structure layer. The first layer is disposed along a first side of the structure layer. The second layer is disposed along an opposing second side of the structure layer. The second layer is positioned to prevent at least a portion of the cementitious material from migrating out of the structure layer.

A cementitious composite comprising:
- a structure layer defining a plurality of open spaces;
- cementitious material disposed within the plurality of open spaces of the structure layer;
- a first layer disposed along a first side of the structure layer;
- and
- a second layer disposed along an opposing second side of the structure layer, the second layer positioned to prevent at least a portion of the cementitious material from migrating out of the structure layer.
A cementitious composite comprising:
- a first layer;
- a second layer;
- a structure layer positioned between the first layer and the second layer;
- and
- cementitious material positioned between the first layer and the second layer;
- wherein the second layer defines (i) a retaining surface positioned to prevent at least a portion of the cementitious material from migrating out of the structure layer and (ii) a plurality of apertures positioned to facilitate a fluid flow through the retaining surface into the cementitious material.
A cementitious composite comprising:
- a first layer;
- a second layer;
- a structure layer positioned between the first layer and the second layer;
- and
- cementitious material positioned between the first layer and the second layer;
- wherein the structure layer includes fibers arranged with varying density in at least one of a longitudinal direction, a lateral direction, or a thickness direction.
