ABSTRACT:
A concrete manufacturing process includes pouring a fluidized cement containing a short fiber as an admixture into a concrete manufacturing mold; applying a predetermined level or levels of pressure to the entire fluidized cement poured into the mold, while a gas is introduced into the cement; and hardening the cement as the gas introduced thereto forms bubbles which burst and generate vibration when they are vented through a venting section provided for the mold. When the cement is hardened to some degree, the hardening may be continued in a temperature-controlled liquid bath or followed by curing with steam.
