The moladi mortar that is used to fill the formwork
cavity is essentially concrete without stone. The mix
design of the mortar is specifically determined by
laboratory tests that are carried out on local sand or
aggregate, to ensure that quality standards are
adhered to. The density of the mortar will vary
depending on the sieve grading of the sand used, but
will range between 1600 to 1800 kg per cubic metre.
The moladi mortar mixture produces a fast curing
aerated mortar which flows easily, is waterproof and
possesses good thermal and sound insulating
properties.
moladi Thermal Properties
Fly ash can be used as a cement extender in order to
reduce the volume of cement used without negatively
affecting the required compressive strength - MPa. A
compressive strength of between 15 and 30 MPa can
be achieved in a 28-day period, depending on the
cement: water ratio. Under normal conditions the
mortar sets during the night (12 to 15 hours) and the
formwork is removed the following morning. There is
no need to vibrate the mortar in order to achieve a
smooth finish.
At the start of each project, local building material
tests are carried out to determine the unique mix ratios
required to achieve the compressive strength
requirement of the walls, which is specified by the
appointed project Engineer.
All moladi structures have steel reinforced internal
and external walls. The reinforcing design is specified
by an independent, certified Engineer; according to
the requirements of the structure, which is dependent
on soil conditions such as clay, expanding soils,
collapsing soils, dolomite etc. The Engineer would
also take into account if the structure would be
subjected to earth tremors, quakes or hurricanes. As
moladi structures are uniformly and monolithically
cast, with the reinforcing placed in strategic positions,
the building is more resistant to seismic movement.
All the electrical and water piping is positioned onto
the formwork prior to the location onto the formwork
and cast in situ to eliminate the need for cutting or
chasing of walls.
