Issues before brick industry and brick making machines in India

The brick industry forms the backbone of the construction industry. The unorganized sector, the brick sector, is very large and wide in India. The brick production of India is second largest in the world after china. The sector is increasing because of growing demand of bricks from construction and housing industry. To cater to this huge demand, it is estimated that 150,000 units are employing more than 8 million workers.

The major challenge before the brick industry is that it is highly polluting industry. The main reason for this is the obsolete technologies used in the brick making. Most of the places, where bricks are made experience heavy local pollution. The carbon dioxide, carbon monoxide, and nitrogen oxide cause pollution of the air. The bottom ash left behind as residual from burning coal is the other issue. The respiratory problems and damage caused to nearby agriculture land is the major cause of worry to agriculturist.

Brick industry has to compete for resources which are also used in other industries. The coal is used on steel and also in brick industry. The brick industry used 24 million tonnes of coal annually, which is the third largest user after power and steel. The top layer of soil is taken for bricks. That destruction of top layer of soil creates problem for agriculture.  The kiln itself takes lot of space and makes land unfit for agriculture.

Since brick making is labor intensive industry, large number of poor people are involved in brick making industry at low remunerations in poor working conditions. Another issue that is related with the nature of brick industry is that it is seasonal work that lasts only 6- 7 months.

Now with the use of brick making machines, the situation as far as pollution is concern may improve a bit.  An affordable clay brick making machine with mixer can mix up to 600 kg of material. Bricks Making Machine .Bricks come from this machine without any defect in the shape at constant speed. The machine can make up to 52 clay bricks in one minute. This machine is especially for stamped clay machines.

The fly ash brick making machines is a single platform machine. It can produces around 10,000 bricks in 8 hours. Thus reducing the amount of labor and time involved considerably. The machine is made with advanced technology and materials .the mixing gear capacity of the machine is 500 kg.

Another fly ash brick making machine called 2 bricks fly ash brick making machine is very easy to maintain and occupies small space. Fly Ash Brick Machine  It can produce around 2500 bricks or blocks in 8 hours. Its concrete mixing capacity is 50 kg. It contains four blades with widening space. It is dual purpose machine as both bricks and blocks are caste on the same machine. But the removal of the brick is manual process.


Fly Ash Bricks: an Eco-Friendly Construction Product

It was reported that the National Thermal Power Corporation (NTPC) has produced more than fifty crores of fly ash bricks in various thermal power stations and used in various construction applications. For sustaining environment, the use of fly ash brick has significantly increased as compared with red clay bricks in last few decades.

The use of mortar is quite less in fly ash bricks as compared as traditional red clay bricks due to their uniform shape and size. Due to the less plastic thickness required as compared to red clay bricks, the use of fly ash bricks saves a lot of saves of cement mortar in various construction applications. Apart from this, the fly ash bricks are extremely environmentally friendly as the fly ash is used for manufacturing of the fly ash bricks.

The fly ash is a by-product of thermal power stations. Since, the fly ash bricks don’t need clay from the soil, it saves the agriculture land. Less energy consumption for manufacturing of fly ash brick, hence it saves a lot of conventional energy that were used for manufacturing of red clay soil. The cost of transportation of bricks can be saved as the fly ash bricks can be effectively manufactured at the site of construction.

 Manufacturing of fly ash brick can be effectively done through the hydraulic or vibratory press by using advanced and ultra-modern Fly Ash Brick Machine .Instead of hydrated lime and gypsum, the ordinary Portland cement can be used in the manufacturing of high quality fly ash bricks.

No breakage of fly ash bricks was reported while transportation or use, due to their high strength. The fly ash bricks are known for their lower water penetration, which ensures minimum seepage of water through the fly ash bricks. Apart from having advances over the red clay bricks, the fly ash bricks are known for their low mechanical strength. For increasing the mechanical strength, the contractors or builders can add marble waste. In addition to this, the contractors can add mortar betweens the blocks for increasing the mechanical strength of fly ash bricks significantly. Large sizes of fly ash bricks cannot be produced due to the limitation of size. The large fly ash bricks are prone to breakage.

The fly ash bricks manufactured by using latest technology Fly Ash Brick Making Machine are known for their high fire insulation. It was reported that the greater Noida development authority had made use of NTPC generated fly ash bricks in the manufacturing of its office buildings. Apart from this, the cafeteria   and management school building of Indian Institute of technology was built by using fly ash bricks. In cities like Pune and Vishakhapatnam, the fly ash bricks are used in the construction of private apartments and industrial buildings.  At Greater Noida, the NTPC’ NETRA office buildings are constructed by using fly ash bricks that were manufactured by NTPC.

The Demands of Fly Ash Bricks Has Increased Manifold in India in Last 20 Years

The fly ash brick is highly demanded in various developed countries for different construction applications but use of concrete/fly ash brick was very limited in different developing countries like India. Some of the major reason for the unpopularity of fly ash/concrete bricks in India was lack of proper fly ash brick manufacturing machines.

The situation of fly ash bricks has changed a lot for last 2 decades in India. Less manual manpower consumption, reasonable cost of production and less environment impact are some of the factors of fly ash brick machines manufactured in India for recent 10-15 years. Due to this recent development, the demands of fly ash bricks has increased manifold in many constructional applications or purposes.

Practically no breakage of fly ash bricks takes place during transportation processes, owing to their optimum strength of fly ash brick. Their high fire insulation capacity, make fly ash bricks ideal of construction of various industrial establishments. The demands of fly ash bricks have increased due to the numerous advantages the fly ash bricks have over traditional bricks.

It was reported by less than 60% of cement and mortar is required for the purpose of joints and plaster, owing to the uniform sizes of fly ash bricks. In addition to this, the amount of seepage of water through the fly ash bricks is reduced considerably, owing to the lower water penetration capacity of fly ash bricks.

Without coating of lime plaster, the gypsum plaster can be applied on the fly ash brick machine. No needs of soaking the fly ash bricks in water for more than twenty hours, only little sprinkling of water is more than enough before use in various construction purposes.

Apart from having several advantages over traditional bricks, the fly ash bricks too had certain disadvantages. The mechanical strength of fly ash bricks is too weak, which can be easily rectified by using high quality of motor or marble wastes in between the blocks.

One of the other disadvantages of using fly ash brick is that it has limitation of sizes as only moderate size of brick can only be made. The larger sizes of fly ash bricks are liable to more predictable breakages.

For standardized construction of different types of fly ash bricks, the builders or other individuals can purchase Fly Ash Brick Machine  from authenticated manufacturers and suppliers. The fly ash brick machines are appreciated among their buyers/clients for their rich attributes such as less power consumption, compact design and enhanced functional life.

The demands of traditional Bricks Making Machine has reduced in urban cities in India for last 2 decades due to large demands of fly ash brick as compared due to traditional bricks. The demands of fly ash bricks has increased among builders and property developers of apartments, shopping malls, industries, bridges and other establishments.
