Cement Stabilized Masonry Interlocking Blocks

Published on 18 May 2022. Written by Vinay Raj

The requirements of construction materials are increasing day by day due to the continued infrastructural growth. Because of this large quantity of waste is also generated every year. Waste generated from the aluminium industries like aluminium hydroxide and many more wastes are generated from the industries while processing the raw materials.

These wastes generated from the industries creates serious problems. Disposal of this waste requires huge space and also pollutes the environment. So, these materials can be used in a proper way to lessen the pollution to the environment.

Aluminium hydroxide is added as a stabilizer in cement and as a flocculating agent in soil. It is also used as fire-retardant as it is sensitive to the moisture content variations. Granite processing industries generate waste in the form of a slurry. From this slurry granite powder following components are obtained, SiO₂, CaO and even it possesses cementitious properties. So, by using these materials we can produce cement stabilized masonry interlocking blocks.

Studies can be made to know the optimum mix proportion soil, aluminium hydroxide, granite powder, and cement to attain a good strength.

Requirements:

Cement, fine and coarse aggregate.

Knowledge of mix design

Knowledge of interlocking design

Collection of by-products (aluminium hydroxide and granite powder)

Project Implementation:

1. Collect the by-products from respective sources.
2. Conduct preliminary studies. Perform appropriate tests on granite powder, soil, cement, and aluminium hydroxide and characterize their properties
3. Perform native mix design (ex. M30) and perform tests like compression, etc…
4. Attain a mix design by replacing the granite powder and aluminium hydroxide in different proportions in the native mix.
5. Determine a good block design for interlocking between the blocks.
6. Test the blocks and native mix samples and report the results.

Advantages:

• The environment pollutants are used in an efficient way.
• The use of cement or binding material can be decreased to some extent.
• As we are replacing some content of cement with aluminium hydroxide it is fire resistant than ordinary cement blocks.
• The use of granite powder (which contains slight amounts of CaO) will stabilize cement as it affects the hydration of cement.
• Concrete or reinforced concrete blocks can also be manufactured by choosing a suitable interlocking system.

Conclusion:

The use and study of these waste materials in the construction will be cost-effective and also will exhibit some extra properties over the native cement/concrete mixes. These interlocking blocks can be molded in the desired shape and size according to our project requirements.
