Micro
Concrete Roofing (MCR) is a cost-effective aesthetic and durable alternative
sloping roof technology. MCR technology
is a result of global research and development effort. The tiles are being
marketed extensively in Latin America, East and West Africa and South East
Asia, over forty million tiles are installed. In India, Development
Alternatives, in technical collaboration with SKAT, Switzerland; introduced
the technology under their building material program supported by SDC (Swiss
Agency for Development and Co-operation). This technology has been widely
excepted, with more than 250 production units currently in operation.
Brief production
process
The mix of cement sand, aggregate and water is vibrated for about 45 seconds
and then transferred on to a high impact polystyrene mould to give MCR tiles
their unique profile. After initial setting for 24 hours, tiles are water
cured for 7 days. This result in great strength and durability of MCR tiles.
Advantages
| ● | Offer more value for money |
| ● | Are highly durable –they have the life of concrete |
| ● | Are lighter than other roofing tiles- allows cost saving on understructure |
| ● | Can be easily installed |
| ● | Can be easily dismantled and reused |
| ● | Can be coloured to user’s preference |
| ● | Reduce heat gain |
| ● | Do not make noise during rains |
Areas
of Application
A variety of roof designs for
farm and country houses, bungalows, verandahs and pavilions are possible
with MCR
tiles. They have also been used on industrial sheds, workshops and
restaurants. MCR tiles offers much versatility for designers, architects and
engineers to create a variety of roof forms.
Development Status

Technical Data
| Annual production | 120,000 tiles with a set of two machines (at full capacity) (200 tiles/machine/day) |
| Land requirement | 60 m2 of covered working area 500 m2 (For raw materials, production, curing and stacking) |
| Electricity requirement | 5.0 kVA |
| No.of jobs created | 9 (1 supervisor, 2 skilled, 6 Unskilled) |
Economic Data
| Infrastructure | Rs 95,000/- (for workshop and office space) |
| Equipment | Rs 1,70,000 (for two machines, accessories) |
| Training and know how transfer | Rs 15,000/- |

Business
MCR is
highly profitable for micro and small scale building material producers. A
capital investment of about Rs. 3 lakh offers a turnover of Rs 8,40,000/-,
which yields profits upto 40% of the investment, within the first year of
operations. The equipment is supplied by TARA (Technology and action for
Rural Advancement), a leading sustainable technology marketing organisation.
