Fly ash is a fine powder that is a byproduct of burning pulverized coal in electric generation power plants. Fly ash is a pozzolan, a substance containing aluminous and siliceous material that forms cement in the presence of water. When mixed with lime and water, fly ash forms a compound similar to Portland cement.

Two classes of fly ash are defined by ASTM C618: Class F fly ash and Class C fly ash. The chief difference between these classes is the amount of calcium, silica, alumina, and iron content in the ash.

Fly ash can be used as prime material in many cement-based products, such as poured concrete, concrete block, and brick. One of the most common uses of fly ash is in Portland cement concrete pavement or PCC pavement.

Fly ash reacts with lime in the presence of moisture to form calcium silicate hydrate which is the binder material. The raw mix is molded in the molding press/machine, pressed under a pressure into bricks. The bricks are then with drawn from the molding machine and they are air dried under the sun and kept for 1 day.

Fly ash bricks are hi-tech well-improved quality bricks used for construction of brick masonry structures. They are used as replacement for normal clay bricks and has better properties than it. Fly ash bricks competitive in comparison to the conventional clay bricks and provide enormous indirect benefits.

Fly ash concrete has better workability and pumpability. It also hydrates more slowly, which reduces the heat of hydration—critical to reducing cracking in mass concrete placements. All of this makes fly ash concrete more durable than plain portland cement concrete. In addition, concrete with fly ash costs less, because fly ash is typically cheaper than cement.

Fly ash is commonly used in concrete in replacements that are ranging from 0 to 30% by mass of total cementitious material. A high percentage of the cement within concrete can be replaced by Fly Ash without adversely affecting concrete properties.

BHARATMACH (BHARAT Hydraulic) block making machines are designed to make Hydraulic Technology OR Vibro-pressed hollow blocks, Fly Ash Bricks, interlocking blocks, pavers, a variety of special products and custom made-designs. BHARATMACH interchangeable moulds are designed to meet any customers need and specifications.

1. Same number of Fly Ash Bricks will cover more area than clay bricks. Fly Ash Bricks have High Fire Insulation.

2. Due to high strength of Fly Ash Bricks, practically no breakage during transport of Fly Ash Bricks and use.

3. Due to uniform size of Fly Ash Bricks mortar required for joints and plaster requirement reduces almost by 50%.

4. Due to lower water penetration seepage of water through bricks is considerably reduced.

5. Gypsum plaster can be directly applied on these Fly Ash Bricks without a backing coat of lime plaster.

6. These Fly Ash Bricks do not require soaking in water for 24 hours. Sprinkling of water before use is enough.

natural curing can be upto 15 days long. During monsoons its not possible. there are 3 main methods of increasing speed of curing and have it insulated from weather conditions so that you have bricks 24 x 7 x 365 all through the year. The land requirement for storing is also negligible compared to natural curing where you need large piece of land. The first method is mist curing where saturated steam is let in teh chamber this brings the curing time from 15 days to 3 days. The second method is using high power press and stack the green bricks in a chamber designed to have perfect air flow to use the heat emanating from the exothermic reaction inside the brick to help them cure in 24 - 30 hours. The third method is using an autoclave wherein low pressure steam is used this method is fastest and curing time can be as low as 8 hours.

Buying a machine that makes bricks is a great investment choice for cost-conscious home builders as well as fulltime sellers of building blocks. Brick maker machines have revolutionized the age old process of making bricks by hand – where clay was mixed with water, cast in the molds, dried, and then fired in the kiln. Although the process largely remains the same, humans now use semi-automatic machines such as fly ash brick making machines, hydraulic brick making machines, etc. to manufacture building bricks and blocks. With the market awash with various types of machines that make bricks, you may not be quite sure of the right choice of a brick maker for your project. Here are the key considerations when purchasing a brick maker machine:

1. Scale of operations: When shopping for a machine for making blocks, you should keep in mind the production capacity of the appliance. If, for example, you plan to buy a brick maker machine to create bricks for your house building project, a small scale apparatus will serve your purpose. On the other hand, you should go for a large scale brick maker machine if your plan is to start a block making business.

2. Quality of machine: The type of material used to construct a machine usually determines the quality of the apparatus. It is important, therefore, to ensure that your machine of choice is built with high quality materials that can stand the test of time while reliably producing high quality bricks and blocks. You should particularly check the quality of hydraulic cylinder, pump and valve since they have great effects on the machine’s hydraulic system. Be sure to buy a brick making machine whose forming molds have been dealt with carbonization as these apparatus have longer service life and are more efficient in the long run. Avoid machines whose forming molds are made from ordinary steel without any treatment as their quality cannot be ascertained.

3. Styles of bricks: Different types of brick making machines produce diverse types of bricks, such as hollow bricks, fly ash bricks, concrete bricks, interlocking bricks, cement bricks, solid bricks, etc. It is important to ascertain in advance that your brick making machine of choice can produce the sort of bricks or blocks you require for your project. Ask your dealer as many questions as possible about the capabilities of each of your prospective machine to avoid disappointments.

4. Levels of autonomy: An autonomous machine is one that is designed and engineered to adapt to changing surroundings on its own, and perform its tasks for extended periods of time without human intervention. Like most other apparatus, machines that make bricks and blocks have various levels of autonomy. It is advisable to pick a machine that enjoys high levels of independence, especially if you need to produce large volumes of bricks.

5. Ease of maintenance: When shopping for a machine, most people consider its features, ease of use, and workmanship, but they tend to overlook a key factor: serviceability. Like any other equipment, a brick making machine requires routine maintenance to operate efficiently and with longevity. You should therefore consider a machine’s ease of maintenance as well as the availability of spare parts.
