wet and dry process of cement manufacturing wikipedia

The main difference lies in the manufacturing process. Wet Cast Pavers. Wet cast concrete is a flow-able form of concrete which is often poured down on moulds from a hopper or truck. It has a higher water to cement ratio. The manufacturing involves pouring out concrete mix to a mould which will be vibrated to push any air bubbles out from the mix.
