Hollow Bricks: Sizes, Weight, Price & Complete Construction Guide
Hollow bricks are a popular construction material used globally for building walls, partitions, and other structures. They offer several benefits, including reduced weight, improved insulation, and cost-effectiveness. In this comprehensive guide, we'll cover the sizes, weight, price, and construction process using hollow bricks, along with international standards, types, pros, and cons.
What are Hollow Bricks?
Hollow bricks are a type of brick that has a hollow core, typically made from clay or concrete. The hollow core reduces the weight of the brick while maintaining its strength and durability. Hollow bricks are widely used in construction for their thermal insulation properties, reduced material usage, and environmental benefits.
Types of Hollow Bricks
- Clay Hollow Bricks: Made from clay, these bricks are a popular choice for construction due to their high strength, durability, and thermal insulation properties.
- Concrete Hollow Bricks: Made from concrete, these bricks are stronger and more durable than clay hollow bricks. They are often used for load-bearing walls and structures.
- Fly Ash Hollow Bricks: Made from fly ash, these bricks are a cost-effective and eco-friendly alternative to traditional clay and concrete hollow bricks.
Pros and Cons of Hollow Bricks
- Pros:
- Reduced weight, making them easier to handle and transport.
- Improved thermal insulation, reducing heat transfer and energy consumption.
- Cost-effective compared to solid bricks.
- Environmentally friendly, as they reduce material usage and waste.
- Cons:
- Lower compressive strength compared to solid bricks.
- May require additional reinforcement for load-bearing structures.
- Can be prone to water absorption, affecting durability.
International Standards for Hollow Bricks
Hollow bricks must comply with international standards to ensure quality and safety. Some of the key standards include:
- IS (Indian Standard): IS 1077: 2015, IS 12894: 2018
- BS EN (British Standard European Norm): BS EN 771-1: 2011, BS EN 772-1: 2011
- ASTM (American Society for Testing and Materials): ASTM C129: 2018, ASTM C1357: 2019
- AS-NZS (Australian and New Zealand Standard): AS/NZS 4455: 2003, AS/NZS 4815: 2006
Sizes and Weight of Hollow Bricks
Hollow bricks come in various sizes, depending on the region and application. Here are some common sizes and weights:
| Size (mm) | Weight (kg) |
|---|---|
| 190 x 90 x 40 | 2.5-3.5 |
| 190 x 90 x 80 | 4-5 |
| 240 x 115 x 75 | 5-6 |
Price of Hollow Bricks
The price of hollow bricks varies depending on the region, material, and supplier. Here is a country-wise price table:
| Country | Currency | Price (per 1000 bricks) |
|---|---|---|
| India | INR | 3,000 - 5,000 |
| UAE | AED | 800 - 1,200 |
| UK | GBP | 200 - 300 |
| USA | USD | 150 - 250 |
| Australia | AUD | 250 - 350 |
Step-by-Step Guide to Construction with Hollow Bricks
Here's a step-by-step guide to constructing with hollow bricks:
- Preparation: Ensure the site is level and clear of debris. Lay a foundation, if required.
- Mixing Mortar: Mix mortar according to the manufacturer's instructions.
- Laying Bricks: Begin laying bricks, using a spirit level to ensure straight lines.
- Pointing: Fill gaps between bricks with mortar and point to finish.
- Curing: Allow the structure to cure for 24-48 hours before loading.
Pro Tip: "When laying hollow bricks, ensure that the holes are aligned to provide maximum insulation and reduce thermal bridging. This will improve the overall energy efficiency of the structure." - Naresh Sihag, Construction Expert
Common Mistakes to Avoid
- Inadequate foundation: Failing to provide a suitable foundation can lead to structural issues.
- Incorrect mortar mix: Using an incorrect mortar mix can affect the strength and durability of the structure.
- Poor brick laying: Failing to lay bricks level and plumb can result in uneven walls and structural issues.
