Cement Jalli

 Cement jallies have occupied an important role in the building constructions. Cement jallies are pierced panels with a thickness of not less than 2.5 cm. They are used in construction of houses, buildings etc. as partition panels in the walls and ventilators.

MARKET POTENTIAL:

  The demand for cement jallies increases correspondingly with the increase of building construction activity which is fast growing in the country. Apart from low cost, other contributing factors to their demand are fascinating designs and functional qualities in building construction. In view of these factors there is good demand for these products and new units can be encouraged in several places including rural areas in the country.

(i)MANUFACTURING PROCESS

The process of manufacturing of cement jallies is simple, as the technical aspects involved are very less and do not require any sophisticated machineries. One concrete hand mixture (local made) and iron or wooden moulds are required for the manufacture of cement jallies. The moulds are lubricated with kerosene oil and kept ready for moulding. Then cement and sand in proper ratio (i.e. 1:3) with proportionate water is mixed to make concrete mix. The moulds are then filled with the concrete mix duly providing reinforcement with M.S. rods and wires at suitable depth. The excess material spread over the mould is removed and the surface is smoothened with the help of a trowel. The jallies in different shapes and designs are then removed from the moulds and kept on a plain dry surface for about 24 hours. These jallies are then immersed in water for 14 days for curing in order to develop strength and make them durable. After curing the jallies are dried and stored for marketing.

 (ii) QUALITY SPECIFICATIONS:There are no quality specifications for the product. However they are manufactured as per customer specifications, design, requirements etc.

 (iii) PRODUCTION CAPACITY (pa)

 It is envisaged that the unit can achieve production capacity of 3,00,000 sq.ft. cement jallies per annum valued at Rs.63,00,000

(iv) POLLUTION CONTROL

 There are no specific pollution control needs/requirements for this type of industry. The workers may be provided with dust masks during mixing operation.

 v) ENERGY CONSERVATION:

 No fuel is required in this process. Hence the question of conservation of energy does not arise.
