R&D Initiatives: ‘No’ to Cement Sand plaster

1) Gypsum Plaster with Spray machine1) Gypsum Plaster with Spray machine

Objective:

Automating the process of wall plastering

Brief description of the process:

High purity gypsum plaster mixed with

retarders is applied to internal walls with

spray machines to get desired thickness.

Major Benefits:

50% Time savings

Better look, feel & finish of the flats

Zero wastage during application

R&D Initiatives: Low/Zero VOC paint with spray

2) Building painting with Spray machine2) Building painting with Spray machine

Objective:

Automating the process

Brief description of the process:

The Primer is applied with the spray machine

followed by two coats of paints by spray.

Major Benefits:

60% Time savings

Uniform finish without any brush, roller marks after painting with spray

R&D Initiatives: Low carbon initiative

3) Ferrocrete for swimming pool3) Ferrocrete for swimming pool

Objective:

Economic design , less time

Description:

The cement mortar mix is reinforced with

chicken wire mesh to form the structure.

Major Benefits:

Any shape possible

Water resisting behavior

R&D Initiatives: Low carbon initiative

4) Lost in place formwork for boundary walls4) Lost in place formwork for boundary wallsObjective:

To identify and implement an alternate

method for boundary wall construction which

is faster than conventional boundary walls

Brief description of the process:

The wall Panels are made using glass fibre

reinforced water resistant gypsum plaster and

fixed at site using infill concrete at joints

Major Benefits:

Due to its ductile property, has got good

earthquake resistance

Faster construction

Low embodied energy (made from recycled

gypsum)

R&D Initiatives: Low carbon initiative

5) Polymer mortars for brickwork5) Polymer mortars for brickwork

Objective:

To do brickwork using polymer mortars in

place of conventional cement-sand mortars

Description:

Pre-mix polymer mortars are directly applied

over the bricks to an average thickness of

4mm on sides and top to achieve bonding

between the brickwork.

Major Benefits:

Zero cement

Zero River sand

Zero water (during & post application)

Cost effective

Better bonding strength than conventional

R&D Initiatives: Low carbon

6) Concrete door frames6) Concrete door frames

Objective:

To identify an alternative cost effective less

moisture absorbing door frames in place of

wooden door frames

Brief description of the process:

Can be monolithic , can be precast

Major Benefits:

Resistance to cracking, Shrinkage

Less Water absorption

Resistance to twisting / warping, borers

Higher strength. NO to WOOD

R&D Initiatives: Conventional Construction

Objective:

To identify an alternative cost effective

external plaster solution in place of

conventional cement- sand plaster,

Brief description of the process:

The fly ash blended sand is mixed with

cement in a ratio of 1:7 to make plaster mix

for external walls

Major Benefits:

Less cement required hence cost effective, low

carbon intensive

No impurities, No sieving of sand

7) Fly Ash blended sand for external plasters7) Fly Ash blended sand for external plasters

R&D Initiatives: Conventional Construction

8) Alternate Floor protectors8) Alternate Floor protectorsObjective:

To identify a cost effective alternative floor

protectors which is easy to do immediately

after flooring

Brief description of the process:

Polypropylene Sheets (250 GSM, 500GSM) in

place of conventional POP and plastic sheet

Major Benefits:

Easy to install

Tidy work environment

Can be re-used, recycled

Less labour

50% time savings

Got scrap value even after re-use
