PRESENTED BY VARUN VS7 CE ENGGRoll Number:27

INTRODUCTION

• Durable, quality housing and a viable alternative .

• Supplies and assists with the full range of requirements .

• Applying the highest quality standards and a disciplined

approach to the construction method…

• The simplicity of the construction process .

• The six key challenges.

MOLAD I CONSTRUCTION TO THE SOCIETY

• Challenge the tradition bound construction industry.

• Empowerment of the poor community.

• The upliftment and empowerment of communities.

• Sustainable Development.

• Sweat equity.

• Help for those at the bottom of economic pyramid.

A Typical Moladi building

FORMWORK

Moladi formwork

• Emphasis on quality and Efficiency.

• Light weight mould.

• Easy transportation.

• No plastering, no beam filling and no skilled labour needed.

MORTAR MIX

Mixing and placing of mortar

• Custom mix design.

• Fast curing aerated

mortar.

• Water proof.

• No need to vibrate.

REINFORCING

Reinforcements used in Moladi buildings

• Designed by a certified

engineer.

• Depends on the

requirements, soil conditions

,etc.

• Placing of reinforcement

• Electrical and water piping is

located onto the formwork

and cast in situ.

PROCESS

Step 1

• Molad I formwork is delivered to the site.

• Start the erection of Moladi.

• Panels assembled by general labourers .

Erection of Moladi Formwork

Step 2

• Internal panels are erected.

• Window frames and block-outs are placed in positions.

• Mesh and reinforcing details are placed.

• External panel are then erected.

Positioning the formwork

Completion of formwork

Step 3

• Door frames and block-out are positioned

• Erection of moladi completed.

Pouring of mortar

Step 4• Filling of the wall cavity with 3.4m3 of an aerated mortar

mixture.The pouring is completed.

THE NEXT DAY……..

Step 1

• Moladi formwork is removed.

• Panel moved and immediately re-erected on the next foundation.

• Removing of moladi completed.

Finished.

Removal of moladi formwark

Painting the surface

Step 2• Panting the surface with cementatious water based

paint.• Oil or water based paint can also be used at a later stage.

Finally the roof is constructed

Step 3• The walls are 1.5 to 2.0 mPa strong with an ultimate

strength of 10 to 20 mPa, achieved in 28 days, depending on the mix design of the mortar (C:W Ratio) .

• Engineer certified roof is constructed

Finished structure

Step 4• Final finishing's, such as plumbing and electrical fittings,

are completed• The structure is now ready for occupation

LABOUR

• Unskilled labour.

• Comprehensive training programme.

• Engineer design.

• Optimized and sequential process .

Positioning of Molad i formwork

ADVANTAGES

• Reduction in the cost of construction ..

• not dependent on skilled labour..

• construction of low-cost and affordable houses, …

• an affordable technique to effectively build durable, earthquake, cyclone resistant shelter.

• creates jobs within unskilled communities.

• reduces pollution and environmental destruction.

TRADITIONAL BRICK OR BLOCK CONSTRUCTION• Labour intensive• Compressive capacity only• Skilled labour• Mortar shrinkage• Thermal expansion and contraction• Levelling• Erratic supplies = erratic delivery• Waste• Rework• Slow delivery• Inconsistent quality

TESTS CONDUCTED

Water penetration test

• The standard of this test method is based on the city of Cape Town’s rainfall of 1,000-mm per annum, a wind speed of 30 meters per second and is conducted over a 24-hour period.

• The test has certified the walls are waterproof.

Soft body impact test• Soft body impact test is

carried out by slamming a 30 kg bag, by means of a pendulum, against the surface of the wall.

• Height of swing at 900 mm above the point of impact. To meet the safety criteria, the bag is released from a height of 1800 mm above the point of impact.Any sign of cracking, surface damage or collapse is noted. There was no damage.

Chisel impact test

• Chisel impact test is carried out with two consecutive strikes of a chisel, which is released from a height of 375 mm above the floor level. Just above the point of impact a slight indentation of less than 3 mm was visible.

CONCLUSION• Holistic building technology • Fast track, cost effective, transferable construction

technology• A solution in housing the masses of the world• Construction of low-cost and affordable houses, schools,

clinics and other structures• It’s a solution for instant housing for the rehabilitation of

displaced peoples ,from natural disaster or dam construction ,etc.
