Pouring Resin;
I seem to recall a tip from Model Railroader with regard to pouring resin in this case to make a water feature, and to avoid including air bubbles the tip was to pour the resin down a stick and use the stick to direct the flow of resin.
If you wish to make a shaker table then mount your mould[s] on a board or an old table and then run a drill with an off centred bit in the chuck and the resulting vibrations from the motor and the shaking from the chuck will help to work any bubbles to the surface of the mould.
Concrete fact; Concrete weighs @ 2.2 tonnes per cubic metre ie 2.2T per M3
Formwork can also be thought of as like how a cake tin is used in cooking.
Whatever shape or texture the formwork is in will be reversed in the finished product.
The bridge abutment model in the photo above would be described as off the form board finish and was formed using rough sawn form planks of 6 or 8 inches in width. The patchy parts of the surface were caused by insufficient compaction/vibration of the concrete during placement somewhat akin to the air bubble problem in the hobby resin pour.
