A method and apparatus for molding a reproducible uniform concrete test cylinder. Concrete is poured into a concrete test cylinder mold. A cap having at least one excretion hole is placed on the top portion of the concrete test cylinder mold. The cap is pressed against the top portion of the concrete test cylinder mold thereby excreting excess concrete through the excretion hole in the cap. After the cap is separated from the poured concrete, the poured concrete is allowed to cure within the concrete test cylinder mold for a predetermined time. Then, the cured concrete is removed from the concrete test cylinder mold thereby producing a uniform and reproducible concrete test cylinder.
