TRC. is a new material, bringing with it new opportunities,
the sketch illustrates how it can be made into a kit for a reef,
one that gets "put together " rather than being cast.
Wet concrete work on site iis reduced to decoration and
the casting of the heavy [about 75% of the total mass] base ring,
into a permanent TRC. shutter.
The cone elements are held together [and spaced] by
the use of either pultruded FRG rods coated with CemForce
or concrete matrixed glass rods which get bonded into
to the discs that are used to create the cone or ball. The unit
shown ships thin / light, remains light as it becomes LARGE,
until the base ring is cast to add mass.
The completed can make use of a Polyform float if required,
or can be towed on a skid platform which tilts to allow it
to slide off. Its construction will have it sink as though it has a
parachute fitted....
TexCell mouldings will be about the same density as wood,
the shipping weight about the same as three sheets of [4 mm]
plywood up to 4 foot, 50 % more for larger reefs. Probably
less than the weight of an FRG mould to make a Reefball of a
similar size, there are two possibilities
1/ ship complete units, with exception concrete for base,
2/ ship textile skeletons, plus FRG moulds for conversion on site.
The aim is to be make TRC. technology available to companies with an established market.
