How to Mix Pratliperl with Cement
Introduction
An
Innovative
Heat Proofing and
Climate Control
Plastering Material.
Sand not required
use Sinicon PP instead.
All the principles of good concrete practice apply to Pratliperl mixes.
Equipment
A mechanical means of mixing is suggested. A pan mixer is preferable as a drum mixer tends to make
balls. If this equipment is not available, manual mixing with shovels is acceptable.
As Pratliperl is a non-absorbent volcanic glass, water will not be absorbed into the material. The use of
a sealed, leakproof container is therefore recommended to prevent leaching of the required amount of
water.
Mixing Instructions
1. Mix Pratliperl and cement in a dry state first (a little water may be used to dampen slightly
in order to suppress dust).
2. Add the correct amount of water (refer to ‘Mix design and suitability guide’ – and note that
the water is given in litres per 100 litres of Pratliperl!). The product may appear very dry,
especially if hand-mixed, but this is correct. It is important to monitor the amount of water
added since small differences in water content have a large effect on overall consistency
and slump.
3. Mix, but do not overdo mixing time – about 30 seconds in a pan mixer is all that is required
(longer mixing entrains too much air).
Yield
• Approximately 11 bags of Pratliperl will be required for each cubic metre of concrete/plaster
to be mixed (cement and water will be added to this quantity of Pratliperl.) This applies to
all mixes mentioned in the mix design and suitability guide.
Gunnite and Loose-fill
Pratliperl concrete may also be gunnited. Because air velocities are used than for ordinary gunniting
procedures, the rebound is lower. A further advantage is that the rebound can be re-used.
PRATLIPERL can also be used as a loose-fill (without cement) to fill cavities for thermal insulation
purposes.

Some Very Important Tips :
1 The water content is very important. Too much water will yield poor results and lead to
shrinkage, weak concrete and cracking. Use only the water as per the ‘Mix design and
suitability guide’.
2 When plastering, use good conventional plastering techniques. Particular attention should
be paid to the degree to which the plaster has set prior to levelling with straight edge. As
with any plaster, it should be set sufficiently so that it is difficult to cause an indentation by
applying thumb pressure. If the straight edge is applied prematurely, it will cause the
plaster to debond from the wall and slump cracks will form. On smooth surfaces, use
Pratley Plaster Grip Primer.
3 As with any concrete or plaster, proper curing under damp conditions and out of direct
sunlight is vital for success.
4 The application will determine the exact water : cement ratio. For example– for casting
and plastering applications, the user may decide to use the high water content.
(Refer to ‘Mix design and suitability guide’), whereas for screeds, a drier consistency and
stronger product may be preferred, hence, a lower water content may be chosen.
5 Once applied, the surface must be kept moist for the first 14 days while curing. If the
finished product is to be exposed to direct sunlight or fast cured, contact our office for
advice on specialised additives.
Example
I wish to plaster my company’s server computer room internally to improve thermal insulation:
1. Referring to the suitability guide, a 4.5:1 mix is selected since it can be plastered with
ease and has sufficient strength.
2. The wall area of the room is 80m2 and the plaster is to be 30mm thick. Assuming 11 jumbo
bags Pratliperl per m3 : for 2.4m3 I will need 2.4 x 11 bags (each 100 litres) of Pratliperl,
i.e. 26.4 (or 27) bags. For a 4.5:1 mix, this requires 17.6 (or 18) x 50kg bag cement
(33litres each), since 1 bag of cement is required for every 1.5 bags Pratliperl.
3. The higher water option should improve plasterability. The table indicates that 24.2 litres
of water is required for every 100 litre bag of Pratliperl used.
4. The PRATLIPERL and cement are first mixed in the dry state. Water is then added and
mixed in further. This may be done on a non-absorbent floor using a spade.
5. As the substrate is smooth, Pratley Plaster Grip Primer is painted on before plastering to
ensure adhesion. The plaster is applied in the conventional way, once the Pratley
Plaster Grip Primer has dried until “just tacky” (approximately 10 – 20 minutes).
6. Once the plaster is set beyond the gel state, a straight edge is used gently to obtain a flat
surface.
7. It is then float finished; first wood float with a little water splashed on with a brush, and
then by using a steel trowel.
8. Finally, it is covered with a wet Hessian – sprayed regularly for the first 72 hours to ensure
that it remains damp.

What is 'K' - value?
ENERGY SAVING CALCULATION
Pratliperl Plaster v/s Conventional Plaster
'K' = the thermal conductivity of a material. Every material has its own unique thermal conductivity or 'K'
Value. Pratliperl has a very low thermal conductivity. Pratliper ; K = 0.15 Watts/m. °C. This means that it will
not allow heat to pass through it easily.
Rate of Heat Exchange
Q in Joules = K a (Temp 1 - Temp 2) x t
L
W = Q/t = K a (Temp 1 - Temp 2) x t
L
K = W x L = K = Watts x Meters
a x (Temp 1 - Temp2) meters² (Temp 1 - Temp2)
K = Watts
meters °C
ie. K = W/m. °C
Q = Rate of heat exchange (Joules)
K = Thermal Conductivity
a = Area in square meters
t = Time in seconds
Q/t = Watts
L = Thickness
ø1, ø2 = Temp 1, Temp2 in °Kelvin
ø1- ø2 = Temperature difference
What is 'u' value
'u' = heat loss per m² through a specific thickness of medium. The same material, but with different thickness
have different 'u' vlues. u = K/m = w/m°C.
Rate of Heat Loss through a specific thickness of material:
u = k = W/m°C = Watts
Thickness m m²°C
K = Thermal Conductivity
L = Thickness
From the formula, we can see that the Rate that Heat is lost through a medium is dependent on the following:
1) 'K' value (thermal conductivity) of a material.
2) The thickness of the material.

The 'u' value of Wall of Room 2 can be calculated as follows:

The proportion of difference is hence : 0.536 = 1

CONCLUSION
The total k value of wall =
sum of 1 of each material.
k
Typically, a plastered 280mm
- cavity wall has a k-value of
1.5W/m °C
The total k value of wall = sum
of 1 of each material.
k
Typically, a Pratliperl plastered
280mm - cavity wall with loose
Pratliperl fill in the cavity has a kvalue
of 0.15W/m °C
A Pratliperl plastered wall with loose Pratliperl fill will lose only a tenth (0.1) of the heat (or in other words
heat that would enter in to the room) that an ordinary 280mm plastered cavity wall would loose.
Example, if the cost of electricity is (US$/Dhs/Rs) 1.00 per KW/Hour and that the room must remain at a
constant temperature of 5 °C and the outside temperature is 25°C it would cost 10.00 or 10 times more per
KW/hour to keep the inside temperature of Room 1(with conventional plastering) at 5°C compared to Room 2
(Pratliperl Plastering).
Thus the total cost saving in energy through Pratliperl Plaster solution is 90%.
