gypsum plastering vs cement plastering
No Shrinkage Cracks
Saint-Gobain Gyproc gypsum plaster is completely free from shrinkage cracks due to is self-setting properties.
Shrinkage cracks occurs in sand-cement plaster due to sudden change in moisture of concrete arising out of heat of hydration. To control heat in concrete and reduce shrinkage cracks in sand-cement plaster, water curing process is mandatory for 20-21 days. Water curing is labor intrinsic and time consuming. Monitoring of water curing process for large projects is a big challenge.
Faster Construction
Saint-Gobain Gyproc gypsum plaster does not require any water curing. Gypsum Plaster with adequate initial and final setting time improves workability and provides a ready paintable surface within 3-4 days. This is net savings of 24 days of construction time.
Sand-cement plaster is mixed at site in various proportions (4:1 or 5:1) to arrive at desired strength. Sand-cement plaster requires total 28 days (water curing + POP punning) complete curing of surface to attain paintable surface.
Light weight Construction
Saint-Gobain Gyproc gypsum plaster is 50% lighter in weight (density of approximately 700Kg/m3) in comparison to traditional sand-cement plaster (density of 1860 kg/m3). Using Saint-Gobain Gyproc gypsum plaster for internal plastering thereby decreases the load on the building. Technologically Saint-Gobain Gyproc Gypsum Plaster is light weight but still conforms to standards of the compressive strength required for Internal plastering. Saint-Gobain Gyproc Gypsum plaster comprehensive strength ranges from 8N/mm2 to 4N/mm2**
**Above parameters are tested under lab conditions.
No Curing (Water Saving)
Saint-Gobain Gyproc gypsum plaster gives freedom from water curing process thus saving cost of water and labour.
Sand-cement plaster requires water for curing to the tune of 0.6 kg/m2/day. A project of 1 Lac sq-m will require water to the tune of 60000 liters daily. With minimum curing time of sand cement plaster as 25-28 days, the quantity multiplies manifold.
Water required for sand-cement per square feet is 1.56 Litres
Water required for Gypsum plaster per square feet is 0.00092 Litres
Elimination of River Sand
Saint-Gobain Gyproc gypsum plaster comes in ready to use bags. Just addition of Saint-Gobain Gyproc gypsum plaster to clean water at site in prescribed proportion and we are ready for plastering. Gypsum plaster is a most proven alternative method to Sand-cement plaster for internal plastering applications. River sand mining is strictly banned in many states of India.
GREEN Building Certified
Saint-Gobain Gyproc gypsum plasters are infinitely recyclable. Saint-Gobain Gyproc gypsum plasters are GRIHA and GreenPro certified. “GRIHA and GreenPro” certifies that the Saint-Gobain Gyproc gypsum plasters are environment friendly throughout its Life cycle. Griha council is joint initiative of “Ministry of New and Renewable Energy”, “Government of India” and “The Energy and Resources Institute (TERI)”. GreenPro is an initiative by Indian Green Building council (IGBC). Saint-Gobain Gyproc gypsum plasters also conforms to LEED requirements which helps in getting “US Green Building Certification” (USGBC).
Reduced Electricity Bills
Saint-Gobain Gyproc gypsum plasters have low thermal conductivity (0.25 W/m-K) as compared to Sand Cement Plaster (0.72 W/m-K). Lower the thermal conductivity of material, higher the insulating properties. Lower thermal conductivity helps in keeping house cool in summer and warm during winter which in turn save energy cost.
The exact difference in temperature can be calculated basis various parameters and quite complex theoretical calculation.
