Abstract
A method for manufacturing a reinforced cementitious structural member having a predetermined shape and size includes providing a mold having a cavity which corresponds to the shape and size of the member, placing at last one permeable fibrous mat into the cavity, introducing a slurry of cementitious material into the cavity so that the slurry of cementitious material fills the cavity and infiltrates and encapsulates the fibrous mat, curing the reinforced cementitious material, and separating the cured reinforced cementitious structural member from the mold.
Claims16
A method for manufacturing a reinforced cementitious structural member having a predetermined shape and size comprising:
- providing a mold having a cavity which corresponds to said shape and size of said member and having a bottom;
- placing at least one permeable fibrous mat into said cavity, said permeable fibrous mat corresponding in size and shape to said cavity;
- introducing through at least one vertical stand pipe, a free flowing slurry of cementitious material directly toward said bottom of said mold, said slurry of cementitious material forming a stream of cementitious material which spreads through interstitial voids of said fibrous mat in a downward movement until all said interstitial voids are completely infiltrated to said bottom of said mold cavity, wherein said cementitious material then spreads outwardly and upwardly filling said cavity and infiltrating and encapsulating said fibrous mat to form a reinforced cementitious material;
- curing said reinforced cementitious material to form said reinforced cementitious structural member;
- and
- removing said cured reinforced cementitious structural member from said mold.
In a method for manufacturing a reinforced cementitious structural member having a predetermined shape and size comprising:
- providing a mold having a cavity which corresponds to said shape and size of said member and having a bottom;
- placing at least one permeable fibrous mat into said cavity;
- introducing a free flowing slurry of cementitious material into said cavity to form a reinforced cementitious material;
- curing said reinforced cementitious material to form a reinforced cementitious structural member;
- and
- removing said cured reinforced cementitious structural member from said mold, the improvement wherein said permeable fibrous mat corresponds in shape and size to said cavity and said free flowing slurry of cementitious material is introduced through at least one vertical stand pipe directly toward said bottom of said mold, said slurry of cementitious material forming a stream of cementitious material which spreads through interstitial voids of said fibrous mat in a downward movement until all said interstitial voids are completely infiltrated to said bottom of said mold cavity, wherein said cementitious material then spreads outwardly and upwardly filling said cavity and infiltrating and encapsulating said fibrous mat to form said reinforced cementitious material which is cured to form said reinforced cementitious structural member.
