Raw Material and Process Flow Chart

Raw materials in hollow bricks are made of cement, stone chips, 0.5 raw, sand, and stone dust. Also, you can purchase raw materials from nearby districts and other states. Ordinary Portland Cement is the cement material used in hollow concrete blocks.

First, mix cement, stone chips, sand, etc. in the ratio of 1: 6 or 1:12. This mixture is added to the vibrator machine. It is then inserted into the desired shape mold. After drying for 24 hours, place the block in the water tank for treatment.

The curing process continues for two to three weeks to give the blocks compressive strength. The blocks are used in the manufacturing process after drying.

  • Proportional
  • Mixing
  • Fixing
  • Clearing
  • Drying.


Determining the appropriate amount of raw materials required to produce concrete of the desired quality under mixing, placing, and curing conditions are known as proportional.

According to Indian standard specifications, the composite material combined in the concrete mixture used to make hollow blocks should not exceed 6 parts to 1 part by the volume of Portland cement. If this ratio is taken based on weight, then it can be about 1: 7 on average. 

The Mixture

The entire mixture of aggregates, cement, and water is intended to ensure that the cement-water paste completely covers the surface of the aggregate. All raw materials, including water, are collected in a concrete mixer, which is rotated for about 1 water minute. 

To Collapse

The purpose of compacting is to fill all air pockets with concrete without free water movement through the concrete. Excessive condensation will result in the creation of water pockets or layers with high water content and poor quality of the product.


Hollow blocks removed from the mold are protected until they have been sufficiently hardened to allow handling without damage. A shelter away from the sun and winds can take about 24 hours. Hollow blocks are thus hardened, which are cured in a treatment yard to allow complete moisturization for at least 21 days.


Loss of moisture causes the concrete to shrink slightly. Therefore, it is necessary that after the treatment is over, the blocks are allowed to dry slowly. You can dry it in the shade normally, or you can use drying machines.

Hollow Bricks Making Machine

Broadly, you can project hollow bricks in two ways. One is by setting up a semi-automatic plant with separate machinery. Another is by installing a fully automatic hollow brick making machine.

For a semi-automatic plant, you will need machinery such as a hydraulically operated concrete block making machine with quadruple vibrators, concrete mixers, platform electronic waiting scales, water dosing pumps, ram and molds, curing beds, and more.

Fully automatic hollow bricks machines are also available. With this type of machine, you can get 10000-12000 output per hour. These are generally expensive, and different raw materials can be used to make different types of hollow bricks.

These types of machines have a PLC automatic control system, interactive user interface, control system, security configuration logic control, production process, and fault diagnosis display. The price of an automatic hollow bricks machine starts at Rs 4 lakh.

Quality Specifications

IS 2185 (Part 1): 2005 Indian Standards: Concrete Masonry Units – Specification (Part 1) Hollow and Concrete Blocks (Third Amendment) The above standards specify the requirements for these parameters: dimensions, blocks of hollow blocks, density, compression strength, water absorption, drying shrinkage, and moisture agitation. However, the quality of hollow bricks should be as per customer demand.

In this above article, I hope you understand about Hollow brick making business. Based on experimental studies, fiber paired hollow blocks have higher compressive strength than conventional hollow blocks. Hollow concrete blocks with polyester strap waste are eco-friendly based on experimental studies, and strap waste can be easily disposed of. When polyester strap waste of 0.10% and 0.12% is added to conventional blocks, it provides an increase in compressive strength.

In 14-day curing, compressive strength is increasing by 20% by adding polyester strap waste. In 28-day curing, the compressive strength is increased by 24% by adding polyester strap waste. This type of hollow blocks is more economical than normal concrete blocks. Fiber aided hollow block falls under grade, which is a type of hollow block as per IS code.
