Title: Prodn. of concrete with optimal consistency - involves monitoring of water addition
Inventor: KILIAN GOTTFRIED
IPC: C04B40/00
Filed: 1992-11-06
Abstract: During production of concrete or mortar, the water content is measured whilst the compsn. is in the form of a stiff consistent mixture and water is added using a standardised metering device. At the same time, other additives can be metered into the mixture. The water content is measured whilst in the stiff condition by passing a current via electrodes through the mixt. and measuring the resistance. Water is then added in response. The mixture consistency is measured by the force of resistance experienced by the mixing tool. This leads to a correction factor which is applied by metering in cement, size and/or other additive. Also more cement can be added. All additions are computer controlled. No more additives can be added once the concrete is being taken from the mixer. Mixing can only start when the mixer is completely empty or rinsing water of under 35l/m3 remains in the mixer. ADVANTAGE - By adding the optimal water amount, concrete of the required consistency and quality is assured.
