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.
Claims4
A concrete manufacturing process which comprises:
- pouring a fluidized cement containing a short fiber as an admixture into a concrete manufacturing mold;
- applying a predetermined level of pressure to the entire fluidized cement poured into said mold, while a gas is forcedly introduced into said cement;
- and
- hardening said cement as said gas introduced thereto forms bubbles which are vented into the atmosphere through a venting section provided for said mold said bubbles bursting when vented into said atmosphere thereby generating vibration which improves affinity between said short fiber and said cement.

- applying predetermined levels of pressure to the entire fluidized cement poured into said mold, while a gas is forcedly introduced into said cement;
- and
- hardening said cement as said gas introduced thereto forms bubbles which are vented into the atmosphere through a venting section provided for said mold said bubbles bursting when vented into said atmosphere thereby generating vibration which improves affinity between said short fiber and said cement.
