The series covers everything from materials and techniques to sources and hazards.
Uncured concrete is difficult to handle directly.
It usually needs some kind of form or structure to control the shape. The dry materials are mixed first. Water is added to the dry mix. Applying the mix to a wire mesh will need a drier mix that feels more like clay and stays in place until it sets. Concrete will get somewhat hard after 4 to 12 hours, depending on the mix and temperature, and can be worked with coarse files or carved at this stage.
