More compact quantities may very well be carried in a skip (a metal container which can be tilted or opened to launch the contents, generally transported by crane or hoist), or wheelbarrow, or carried in toggle luggage for guide placement underwater.
The scale distribution on the combination decides simply how much binder is required. Aggregate with a very even sizing distribution has the most important gaps While including aggregate with lesser particles has a tendency to fill these gaps.
