PROCESS OF FORMING A CONCRETE COLUMN

摘要

A process of forming a concrete column using a concrete column forming tube lined with a flexible and compressible elastomer sleeve having a randomly dispersed rigid granular material encapsulated therein to form a concrete column having a textured surface. The flexible and compressible elastomer sleeve is formed by mixing a liquid elastomer with a rigid granular material and applying the mixture over a textured generally cylindrical form and curing the liquid elastomer. A colorant may be applied to the inside surface of the flexible and compressible elastomer sleeve to form a concrete column having a colored and textured surface.
