Launching Production of Foam Concrete Blocks

Construction business has always been in high demand throughout history because regardless of the economic situation in the country, people keep building and will continue to do so. After all, everyone needs shelter just as much as they need food. And for those who already have their own homes, sooner or later, they will need to renovate them because nothing lasts forever and everything wears out over time.

In recent years, the construction of private properties has become a common trend, where aerated concrete blocks serve as a good alternative to bricks and other materials that require significant investment. So, why not keep up with the times and start your own block production? Not only can you earn a decent income from selling them but also save on building your own home.

What is Aerated Concrete?

Aerated concrete is a mixture of cement and a special foam prepared in advance. The air-filled bubbles in the foam are uniformly distributed throughout the mixture, and the porous effect remains even after it hardens.

In construction, aerated concrete blocks are often used alongside autoclaved aerated concrete blocks because the former are less strong, making them suitable for non-load-bearing structures unlike autoclaved blocks. Hence, a rational decision would be to start producing both types of blocks.

Advantages of Aerated Concrete Blocks Over Other Building Materials

Firstly, the costs of using this material will be significantly lower compared to others like bricks, for example. Secondly, it allows for quicker and easier installation, good sound insulation, and thermal insulation. Another property of these blocks is their resistance to temperature fluctuations and changes in humidity.

Manufacturing Technologies of Aerated Concrete and Block Formation

There are two methods of producing aerated concrete: pressure technology and foam generation.

Pressure technology: Requires lower costs, resulting in competitively priced products. According to this technology, the solution is placed manually in a special mixing device, and then air is blown into it. The mixture is then stirred, poured into molds, and left to set. The drawback of this method is that it produces less strong and porous blocks, requiring synthetic substances to enhance strength at the expense of eco-friendliness.

Foam generator method: Ensures a high-quality and durable product. Dry components are manually placed into the mixer, followed by liquid components, and then technical foam is added. The mixture is pressurized and poured into molds. These blocks are stronger, eco-friendly, and easier to install as they do not crumble.

Shaping Aerated Concrete into Blocks

Cutting technology involves special cutting equipment. Aerated concrete is poured into a specific mold where it sets, then cut into blocks of desired sizes. Timing is crucial to ensure the material is firm enough but not too strong for cutting.

Molding technology entails pouring the mixture into metal molds where it solidifies. These molds vary in cost, and using low-quality ones can lead to defects in the blocks.

Establishing a Small Aerated Concrete Block Production Plant

Depending on the chosen production technology, the initial capital required to set up the plant will vary significantly. For instance, using pressure technology for aerated concrete and molding technology for blocks will cost around $10,000. Employing foam generation and cutting technology would need an investment of $22,000. Alternatively, purchasing a fully equipped production line may require up to $100,000, catering to larger-scale operations.

Firstly, when planning to launch your plant, finding a suitable space is crucial. Whether buying or renting, the space required for producing one cubic meter of blocks is approximately 30 square meters.

Purchasing a complete production line or individual equipment, followed by installation, is the next step. While investing in the entire line is recommended, starting without it is also viable initially. Procuring necessary materials for production, estimated at $2,000 monthly for yielding 30 cubic meters of finished products, is essential.

Additionally, hiring workers for production maintenance is crucial. If the monthly production target is set at 30 cubic meters of blocks, staffing six employees would suffice. The larger the production volume, the more workers will be needed. Calculating the production costs, including electricity consumption, is vital to determine the selling price for profitability.

Prior to starting the business, analyzing the market is essential. Understanding the demand for such products in the target area, assessing the competition, and exploring alternative locations where building materials are transported from distant cities can lower production costs significantly. Experts crafting various business plans suggest that aerated concrete production can be a highly lucrative investment, with a potential payback within 3 to 5 months.
