Usually the concrete is poured at a strength of 20 Mpa and a slump of
80.
Concrete is not less than 75mm thick.
F52 would be the minimum gauge steel reinforcing to use.
Usually the concrete is batched in lots of .2m³ so the measurement of
your job is rounded up to the nearest multiple of .2m³.
Remember, don’t be tempted to pour more than you can handle.
There are two types of finishes recommended for a court yard, a float
finish and a broom finish.
Expansion joints are placed in so that there is no larger mass of concrete
than 12 - 14 m².
Colour , Stencil and Stamped Concrete
The concrete is poured normally and the colour is added on after.
There are several companies making the colour for concrete and a variety
of jobs can be done with this colour, the easiest being floating the colour
onto the surface.
Stencil and stamped take a bit more practice and need a bit more
equipment.
Usually the place of purchase for the colour, which is sold in 20kg. bags,
will have a variety of the stencils and stamped equipment as well.
