Concrete blocks, or besser blocks, weigh around 14 kilograms each. They are great for building projects like retaining walls and foundations. Having an expert blocklayer on the job ensures the blocks are laid properly and efficiently.
In this blog, we’ll discuss the average weights of common block types and how they affect transportation and handling.
Average Weights of Common Block Types
The following are the average weights of common block types in Australia:
- Concrete Blocks: Weigh around 14 kilograms (31 pounds). These are versatile and commonly used for building walls and foundations.
- Lightweight Blocks: Weigh about 10 kilograms (22 pounds). They’re ideal for non-load-bearing walls and easier to handle.
- Hollow Blocks: Weigh approximately 12 kilograms (26 pounds). Feature cavities that provide insulation and reduce weight.
- Solid Blocks: Weigh about 18 kilograms (40 pounds). They are used for load-bearing structures due to their strength and durability.
- Aerated Concrete Blocks: Weigh around 7 kilograms (15 pounds). They are known for their excellent insulation properties and ease of use.
How Block Weight Affects Transportation and Handling
Block weight affects transportation and handling by influencing the ease and cost of moving and placing them. Heavier blocks need stronger equipment and more planning to transport safely, which can raise costs and require specialised machinery. Workers must use proper lifting techniques to avoid injury and keep productivity high.
Lighter blocks are easier to handle and transport, reducing the need for heavy machinery and allowing for faster installation. This can speed up projects and lower labour costs. However, they might not be ideal for all projects, especially where strong load-bearing is needed. Choosing the right block weight helps balance handling ease with project demands.
Considerations for Structural Load Bearing With Different Block Weights
The following considerations highlight the pros of using blocks, ensuring safe, durable structures capable of effectively supporting required loads.
- Material Composition: Dense blocks offer better support than lightweight blocks.
- Load Distribution: Evenly distribute the load to prevent structural failures.
- Foundation Integrity: Examine soil conditions and reinforce foundations as needed.
- Block Size and Alignment: Ensure precise placement for optimal capacity.
- Mortar Quality: Use high-quality mortar for strong bonds and proper curing.
- Environmental Factors: Choose materials that withstand moisture and temperature changes.
- Load Calculations: Factor in live and dead loads; consult load-bearing charts and engineers.
- Safety Regulations: Adhere to building codes and standards with regular inspections.
- Future Modifications: Plan for additional loads to maintain structural integrity.
Do Experts Adjust Construction Techniques Based on Block Weight?
Yes, experts adjust construction techniques based on block weight to ensure safety and efficiency. Handling and transportation methods change, with heavier blocks requiring stronger lifting equipment and more labour.
Foundation design must be more robust for heavier blocks, involving detailed soil analysis and reinforcement. Mortar mixes are adjusted for proper bonding, and precision in placement becomes critical to maintain structural integrity.
Additional reinforcement, such as steel bars or mesh, is often necessary for heavier blocks.
