The strength durability cost and aesthetics of a structure are all greatly impacted by the building materials used in the construction industry. Bricks and blocks are among the materials that are used the most. The basic building blocks for walls partitions and other structural components are these units. Numerous varieties of bricks and blocks are available each with special qualities and uses. Brick Types: 1. Bricks made of clay (burnt bricks) The most widely used and conventional bricks in construction are made of burned clay. Clay is molded into a rectangular shape dried and then fired in kilns to create them. These bricks are robust long-lasting and appropriate for all kinds of buildings. They are categorized according to their quality into four grades (Class I to IV). 2. Bricks made of Fly Ash Fly ash cement gypsum and lime are the ingredients used to make fly ash bricks. Compared to clay bricks these environmentally friendly bricks are lighter have smooth surfaces and provide su...
1. Composition and Production
Red Bricks:
Red bricks are produced using natural clay, shaped into form, and heated in kilns at a very high temperature. This process toughens them and makes them red in color. They are the conventional building material of India and have been in use for ages.
Solid Blocks:
Solid concrete blocks are produced by combining cement, aggregates such as stone chips or sand, and water. The combination is filled into molds, rammed, and cured to create dense, heavy blocks. These blocks don't have hollow centers and are solid throughout.
2. Size and Weight
Red bricks are smaller in dimensions (usually 190 mm x 90 mm x 90 mm), and heavier per unit because they have a denser mix. But since more bricks would be needed to cover an equal area, construction time tends to be longer.
Solid blocks are bigger (about 400 mm x 200 mm x 150 mm or 300 mm x 200 mm x 150 mm) and heavier per unit but have a greater area coverage. This decreases the number of joints and construction time.
3. Strength and Durability
Red bricks possess satisfactory compressive strength (3.5 to 7 MPa) and are deemed durable under regular weather conditions. They are ideal for load-bearing and non-load-bearing walls.
Solid blocks possess greater compressive strength (7.5 to 15 MPa) and improved resistance against water, termites, and other conditions. They are hence best used for high-rise structures and heavy-duty buildings.
4. Construction Efficiency
Solid blocks accelerate construction because they are large in size with fewer mortar joints. There are fewer blocks needed per square meter, and alignment is simpler to maintain.
Red bricks need more labor and time in laying and alignment. They also need more mortar because of the increased number of joints.
5. Thermal and Sound Insulation
Red bricks have medium thermal insulation and poor sound resistance, and they are best for normal residential buildings.
Solid blocks have better sound resistance and marginal improvement in thermal resistance over red bricks, particularly when combined with plaster and insulating materials.
6. Cost
Material price for red bricks is typically cheaper per unit, but the increased quantity of bricks required raises labor and mortar expense.
Solid blocks are more expensive per block, but larger size and shorter construction time tend to equate or even reduce the total cost for large projects.
7. Water Absorption
Classic red bricks soak up moisture at 20%, creating damp spots on interior walls if you don’t apply a damp-proof course. In contrast, solid concrete blocks absorb only 8 to 12%, reducing the chances of water leaking in and crystallized salts blooming on the face of the wall.
8. Environmental Impact
The traditional red brick process strips topsoil and burns huge piles of firewood or coal. This practice scars the land and pumps out fine particulate and noxious fumes, leaving both soil and air a little worse for wear.
Solid blocks are more eco-friendly as they employ industrial byproducts and consume less energy in production.
9. Workability and Finishing
Red bricks are simpler to handle because of their smaller dimensions and are suitable with conventional masonry methods.
Solid blocks are more labor-intensive for handling and setting but provide a superior finish because of their consistent size and shape. They also limit plastering in certain situations.
10. Uses
Red bricks are widely used in conventionally designed buildings, boundary walls, and low-rise residential buildings.
Solid blocks are best suited for high-rise apartments, commercial buildings, and industrial complexes because they are strong and efficient.
Conclusion
Both solid blocks and red bricks have advantages and can be utilized for particular types of construction. The decision is based on the project's size, budget, structural requirements, and local resources. Solid blocks offer a contemporary, reasonably priced, and robust substitute for large constructions, while red bricks are appropriate for small buildings and traditional designs. Solid blocks are becoming more and more popular in the construction industry due to their stronger construction, faster building times, and smaller environmental impact.
