摘要: 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.

摘要: A grid plate of plastic material, with a rough, slippage-impairing top side and a rib-reinforced bottom side. The individual grid plates are kept together by a lockable, but again disconnectable, plug-in connection. The grid plates serve as fastening elements for parking places, road embankments, road ramps, and the like.
