Abstract
A method for forming a uniform texture concrete wall using Shotcrete or other pneumatically projected concrete materials. The method generally includes forming an exterior face mixture from a concrete mixture wherein the large aggregates are removed such that when the face mixture is pneumatically applied to a base structure, the face mixture defines a uniform surface.
Claims20
A method of forming a concrete wall, the method comprising the steps of:
- providing a wall form;
- pneumatically projecting a first concrete mixture in a non-hydrated state onto the wall form to construct a base concrete layer;
- providing a second concrete mixture including large aggregate and small aggregate;
- removing the large aggregate from the second concrete mixture to define a face mixture;
- and
- applying the face mixture to the base concrete layer while the base concrete layer is in the non-hydrated state.

A method of forming a concrete wall, the method comprising the steps of:
- providing a wall form;
- pneumatically projecting a first concrete mixture in a non-hydrated state onto the form to construct a base concrete layer, the first concrete mixture including a combination of large aggregate and small aggregate;
- providing a face mixture formed independent of large aggregate;
- and
- applying the face mixture onto the base concrete layer while the base concrete layer is in the non-hydrated state.
