13. Can you explain the working of concrete pumps?
It uses a valve system to run smoothly and some basic principles of hydraulics. The mixing truck mixes the concrete in its rotating drum and makes it in a liquid state. The liquid concrete is then poured into a hopper, and the hopper continues to churn it so it does not get into the solid state. Later, the concrete pumps suck the liquid concrete out of the hopper through the valve system, and it is then laid down in the area where it is required.
