fly ash can be used as an extender to substitute the use of cement in order to reduce the volume of cement, but will still achieve the same ultimate compressive strength - mPa.
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 meter.
a compressive strength of between 10 and 30 mPa can be achieved in a 28-day period, depending on the cement: water ratio.
as the structure is uniformly cast, with reinforcing placed in strategic positions, the building is more resistant to seismic movement.
the mortar mixture produces a fast curing aerated mortar that flows easily, is waterproof and possesses good thermal and sound insulating properties.
under normal conditions the mortar usually 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.
electrical and water piping positioned within the cavity is cast in situ.
