摘要：
A method for manufacturing a reinforced cementitious columnar structure including: providing a mold having a cavity which corresponds to a shape and size of the columnar structure; placing at least one nonwoven metal fiber mat around the periphery of the cavity; filling the cavity with a slurry of cementitious material containing aggregate having a particle size greater than the size of the interstitial voids of the fiber mat; curing the slurry of cementitious material; and removing the mold.
