Concrete, while in its wet stage, is easily poured and shaped. Depending on the viscosity of the mix, the concrete may have a different workability before it sets and cures. Suction, the flow of liquid into a partial vacuum or region of low pressure, and displacement, the displacing of space of one mass by another, were the two methods tested with various types of concrete by Team 04 (Ilia, Natasa, and Raymond).
