Why Fly Ash Bricks?

Pulverized fuel ash commonly known as fly ash is a useful by-product from thermal power stations using pulverized coal as fuel and has considerable pozzolonic activity. Fly ash refers to the ash produced during combustion of coal. It is the fine powder formed from the mineral matter in coal, consisting of the non-combustible matter in coal plus a small amount of carbon that remains from incomplete combustion. Fly ash is being accumulated as waste material in large quantities near thermal power plants. As the power requirements of the country goes up, the amount of waste produced will also increase enormously creating problems for its safe disposal due to lack of adequate disposal facilities. Its use in manufacture of bricks will be helpful in its disposal and also help in controlling pollution. It is supplied free of cost to entrepreneurs. Fly Ash bricks are made of fly ash, lime, gypsum and sand. The raw materials are blended in desired proportions in a Pan mixer for 4-5 minutes and compressed. They undergo curing for a minimum of 7 days and are then air dried for 7 days. Strength of these bricks can be engineered by varying the compositions. These can be extensively used in all building constructional activities similar to that of common burnt clay bricks. The fly ash bricks are comparatively lighter in weight and stronger than common clay.

FLY ASH IS PROVEN TO BE THE GREEN BUILDING MATERIAL THIS IS THE REASON WHY GOVERNEMENT OF INDIA ENCOURAGES THE USE OF "FLY ASH BRICKS".

Energy requirements for the developing countries in particular are met from coal-based thermal power plants. The disposal of the increasing amounts of solid waste from coal-fired thermal power plants is becoming a serious concern to the environmentalists. Coal ash, 80% of which is very fine in nature and is thus known as fly ash is collected by electrostatic precipitators in stacks. In India, nearly 175 million tonnes (as per data from NV centre on Fly Ash) of fly ash is generated per annum at present and is largely responsible for environmental pollution.

 

Advantages of fly ash bricks:

·       Fly Ash bricks are light weight material compared to clay bricks, so it is suitable for multi storey building, Less weight means Less stress on building, safety assured.

·       Low absorption of heat, FAB (fly ash bricks) absorbs less heat than normal bricks, it keeps your building cool even in summer, hence most suitable for Indian conditions.

·       Thermal conductivity is 0.90-1.05 W/m2 ºC  (20-30% less than those of concrete blocks). These bricks do not absorb heat; they reflect heat and gives maximum light reflection without glare.

·       Uniform shape hence no plastering required if used for compound wall or godowns.

·       Less mortar required in construction and saves 20% morar, because all bricks are machine made and even in shape.

·       High compressive strength compared to normal bricks which is [70-150kg/cm2].

·       Less porous, absorbs very little water, whereas burnt clay bricks absorbs more water during construction. Saves money on water and 20% water  usage during construction and even keeps your building strong during rainy seasons.

·       Fly ash by mixing efficiently with the concrete mix can replace Portland cement that in turn can aid in making big savings in concrete material  prices.

·        It is an environmentally-friendly solution.

·        It improves the strength over time and offering greater strength to the building.
