Unit capable to proudce 8000 Nos. finished hollow blocks of size 100 mm x 150 mm x 225 mm per day will require a investment of Rs. 24.5 lakhs.

24.   Low cost glazed wall tiles

Low cost glazed wall tiles with adequate crazing resistance and impact strength have been developed. The technology is based on red clay gangetic silt deposit of Palta and Howrah, with low maturing temperature (950oC) and offers a means for considerable saving in energy. These tiles have good potentiality in the building industry, public toilets, railways, etc.

25.   Single fired matt glazed ceramic tiles for flooring and facing

The Institute has developed an appropriate technology for the manufacture of single fired matt glazed ceramic tile which could be easily adopted by small scale sector with their limited resources. The product obtained by this process is as per IS: 2838-1964.

The tiles may be used for flooring, interior and exterior decoration. This can also find vast market in low cost housing for rural populations.

The capital investment for a plant of capacity 810 MT finished goods per annum is Rs. 35 lakhs.

26.   Self-setting agent for sodium silicate sand process

The use of sodium silicate as a binder for mould and core production is well established carbon dioxide being used as a hardening agent in the conventional process. The NML has developed a reagent which when used with the sodium silicate sand mixture results in a self-setting mix requiring no further treatment for preparation of moulds and cores. The process is versatile and economical allowing considerable scope for adjustment of bench life and setting time to suit individual requirements. The knockout properties are superior to those of the conventional process.

27.   Fly ash for refractory products

The laboratory has developed a process for the utilisation of fly ash in refractory products. Bricks made using beneficiated fly ash ranging upto 60% along with plastic fire-clay and grog in different proportions finds suitability as fire-clay range of products and hot face insulation bricks. With increase in fly ash percentage the brick attains properties more of the insulating refractory wares, sacrificing its compressive strength. Suggested economic unit for this industry is for the production of 18,000 tonnes of mixed product per year.

28.   Domestic water filter candle

Water filter candles are used for removing harmful bacteria and other suspended impurities from drinking water. Filter candles, portable filter flasks and instant cartridge water filters are prepared according to the above process. Ion exchanger and bacteria inhibitor are used in making these products. Capital outlay for 50 candles/day is Rs. 15,000.

29.   Light weight bricks  

The conventional clay bricks produced are used in the country as building construction material. The light weight bricks made of clay coconut pith mix can now also be conveniently used in building construction. The SEU for this industry is 10,000 bricks per day of the shift with a capital investment of Rs. 8.75 lakhs.

30.   Ferrocement manhole cover

Ferrocement manhole covers are produced using vibro pressing system for obtaining optimum density by campaction. Thin wires at close spacing are used to reinforce several layers of high strength mortar with steel meshes and bars distributed through the thickness of the structure. The manhole covers can be manufactured in the factory for expected loads as high medium and heavy duty. They are 25 to  40% cheaper than cast iron covers now available in the market.

31.   Precast ferrocement tanks, bins, septic tanks, biogas plant digesters, walls for cylindrical guard rooms and kiosks etc.

It is a simple semi-mechanised process for casting thin ferrocement cylindrical units. This process does not require any sophisticated equipment or power and suits well for the rural areas. The process consists of a inner mould for the cylindrical units.

32.   Fibre reinforced concrete manhole cover

FRC manhole cover provide an alternative to the conventional cast iron manhole covers used in water and sewerage mains. They are made from steel reinforced cement concrete with the addition of high tensile cut steel fibres in correct proportions. Fibre reinforced concrete possess superior tensile, wear, impact and fatigue properties over the cast iron

Detailed investigations and field trials, have been carried out on the fibre reinforced concrete over the past several years. The FRC covers satisfy the requirements prescribed in the ISI code for manhole covers. It is 60% of the cost of CI manhole covers.

33.   Prestressed concrete monoblock broad gauge sleepers  

Prestressed concrete sleeper is a highly sophisticated product and is different from other prestressed concrete units, particularly in production technology. The difference arises from the fact that mass manufacturing methods have to be employed for these products. The process developed at SERC is based on the long line method of prestressing. The estimated demand of the railways for this product is about 10 to 15 lakhs per annum. The fixed capital on plant and building for a plant of 50,000 sleepers capacity per annum is about Rs. 1.5 crores, working capital requirement being about Rs. 1 crore. Production cost comes out to be Rs. 1,000 per sleeper.
