Hollow bricks, also described as Porotherm bricks, are a relatively new type of brick that has gained a lot of traction in the construction business. The weight of Porotherm HP (Horizontally Perforated) brickwork is 60% less than that of a concrete solid block. Porotherm Thermo Bricks are more developed hollow bricks that are loaded with a unique insulating layer (rock wool). The bricks were made by Wienerberger, an Austrian multinational company that is regarded as the world's largest brick maker, with over 215 processing facilities in 30 countries, notably India.

Analysis of the concrete block and brick building market in India and a look ahead to 2026

Because of various advantages like longevity, hardness, high integrity, high durability, insulation, and sound insulation, cement bricks and blocks are widely utilized in new structures in the country. Both load-bearing and non-load-bearing walls are referred to as blocks. Because the hilly states of India have high humidity, wetness, and rainfall, the hollow bricks manufacturers are well suited to the northeast region, such as Himachal Pradesh, J&K, and Uttar Pradesh, among others.

The following are the main benefits of starting a brick production plant:

  • Low capital expenditures.
  • The need for bricks is increasing.
  • In terms of company structure, it is value.
  • A fantastic small business concept.
  • Making bricks is a straightforward technique.
  • Only at the municipal and regional level is their competition.
  • There are few labor needs.
  • Raw material waste is reduced.
  • There are a few well-organized participants in the sector.

Other benefits of the product include its lightweight and inexpensive cost, which will help the sector generate more revenue throughout the forecast period. Incorporating polyester strap waste increases compressive strength by 20% after 14 days of cure. Applying polyester strap waste increases compressive strength by 24% after 28 days of cure. This hollow block is less expensive than regular concrete blocks. According to the IS code, fiber-assisted hollow blocks are classified as a class, which is a sort of hollow block.

1 - Company Registration with Hollow Bricks

As a beginning businessman, you must first determine the shareholding or latest hollow brick price of your company. Register your company with the ROC appropriately (Register of Companies). Get a local authority's trade license. Create a current bank account and register for a Pan Card.

You can also register your company as an SSI Unit. It is recommended that you develop a tailored project report if you wish to obtain funding. Apply for GST registration as well. It is recommended that you acquire a Pollution Control Board No Objection Certificate.

2 - Ideal Place

After you've completed your corporate strategy, the next step is to choose a place for your manufacturing. Before deciding on a place, there are a few things to think about. The weather conditions and the temperatures of the geographic location are among the things to keep in mind. And, including industrial buildings to store the bricks, proper warehousing facilities should be accessible. Other essential utilities must be built at the chosen location. After evaluating all of these factors, a location for your business must be chosen from among all possible places.

3 - Hollow Bricks Raw Materials and Process Flow Chart

To begin, combine the concrete, small stones, sand, and other materials in a 1:6 or 1:12 ratio. The clitoral stimulator device is filled with this combination. The mixture is poured into the mold of the specified size. Place the stones in the storage tank to cure after 24 hours of drying.

Furthermore, you can obtain raw materials from surrounding regions and other states. The cementing substance used in concrete and hollow concrete blocks is portland cement. To provide the blocks' compressive strength, the curing process will continue for 2 to 3 weeks. After drying, the blocks are employed in the construction phase.

Proportioning →Mixing →Compacting →Curing →Drying

4 - Machinery for manufacturing

The method or gear you use for manufacturing aids us in determining the raw materials required and where they must be carried to your site. As a result, the very first approach is to create a list of the required equipment. Examine the many models accessible for certain apparatuses, as well as the variations thereof. A review of several manufacturers and suppliers is required. The equipment being used should be both cost-effective and long-lasting. Sort your equipment into categories based on the functions it will accomplish.

5 - Blending

The goal of blending particles, concrete, and water is to guarantee that the hollow brick size mixture covers the aggregates' whole surface. In a cement mixer, all of the raw components, especially water, are collected and rotated for roughly 12 minutes.

6 - Spending

The cost must be examined after determining whether to use the semi-automated or completely automatic gear. You can acquire used machinery if you want to save money on the cost of the equipment. Compare the costs of various machinery, raw materials, and other items. It's important to look at the outcome you're hoping to get. Take into account the following expenses of starting a manufacturing business, such as labor, materials, power, water, and other bills, among others. Your model's cost-effectiveness must be examined.

7 - Compacting

The target of crumpling is to fill all trapped air with cement while preventing free water from moving through the concrete. If there is too much compaction, water pockets or levels with more water will form, which will lower the quality of the products.

8 - Analyze the competition

Only at the neighborhood scale does brick manufacturing confront competition. As a result, you should research your rivals and the prices they are interested in offering. You should concentrate on network-building strategies to succeed in the industry. Make new contacts in the construction industry. They will assist you in growing your business and ensure consistent orders. Maintain solid relationships with the builders, constructors, architects, and other hollow bricks near me professionals in your neighborhood and area. Provide high-quality services to your clients.

9 - Curing

Hollow blocks that have been extracted from mold are covered until they have hardened enough to be handled safely. This could take up to 24 hours in a protected location away from the light and winds. The hollow blocks are then dried in a curing yard for at least 21 days to obtain full moisturization.

Curing is the fifth and last step in the basic process of making cement bricks. The cement blocks retrieved from the mold are protected in this phase until they have cured, allowing adequate handling without injury. This could take up to a day or 24 hours in a protected area away from the heat and winds.

10 - Hollow Brick Standard Requirements

IS 2185 (Part 1): Concrete Masonry Units-Standard, 2005 Indian Standard (Part 1) Concrete Blocks, Hollow Structural (Third Revision) Sizes, hollow block classes, block volume, compressive and flexural, water permeability, shrinkage, and moisture flow are all specified in the aforementioned standard. The hollow bricks' quality, on the other hand, must meet client expectations.
