Fly ash, Lime calcined gypsum and sand, with requisite quantity of water is mixed in proper proportions which produces slow setting cement, the resultant mass pressed is in to bricks of any desired strength. These bricks can be used in building constructional activities instead of common burnt clay bricks. These bricks are lighter in weight and stronger than common burnt clay bricks. The present generation or fly ash in India by thermal power stations is more than 100 million tones per annum. One kilogram of coal of fired yields fly ash ranging from 200 to 500 grams. At present only 6% fly ash being utilized.

Pavement Tiles are building components with an enhanced used and adaptability at low cost. The pavement tiles are used for laying hard, durable and attractive flooring in the courtyards, pavements, walkways, car parking and similar locations. The paving stones are made by using fly ash and cement aggregates at very high pressure to give a hard faced, strong and durable stone like product with or without beveled edges. These stones do not require a sole concrete and needs just a consolidated sand bed for the support. No boding or pointing is necessary and does not require any cement. Paving stones offer the advantage of removing from the position and replacing when ever needed for laying any pipelines etc. and hence eliminates any maintenance expenditure on the flooring. These stones can withstand the weight of a loaded truck and will last for a longtime. They are comparatively cheaper compared to concrete and other tiles.

180 billion tones of common burnt clay bricks are consumed
annually approximately 340 billion tones of clay – about 5000 acres of top layer of soil dug out for bricks manufacture, soil erosion, emission from coal burning or fire woods which causes deforestation are the serious problems posed by brick industry. The above problems can be reduced some extent by using fly ash bricks in dwelling units. Demand for dwelling units likely to raise to 80 million units by year 2015 for lower middle and low income groups, involving an estimated investment of $670 billion, according to the Associated Chamber of Commerce and Industry (Assocha). Demand for dwelling units will further grow to 90 million by 2020, which would requires a minimum investment of $890 billion. The Indian housing sector at present faces a shortage of 20 million dwelling units for its lower middle and low income groups which will witness a spurt of about 22.5 million dwelling, units by the end of Tenth plan period. There is ample scope for fly ash brick and block units.

The process of manufacture is on the basis of single shift of eight hours per day with three hundred working days in a year.
I. To achieve full plant capacity it requires 1 year after trial production.
II. Labour and wages mentioned in profile are as per the
prescribed minimum wages.
III. Interest rate at 14% considered in the project profile. IV. Operative period of project is around 10 years considering technology obsolesce rate and period of repayment of loan.
Project implementation will take a period of 8 months from the date of approval of the scheme. Break-up of activities with relative time for each activity is shown below :-
Nature of activities time period in months (Estimated)
I. Scheme preparation & approval : 0-1
II. SSI provisional registration : 1-2
III. Sanction of loan : 2-5
