Why House buildings are constructed using hollow blocks?
One of the main functions of hollow bricks is to reduce the dead load of the Structure. These are extremely light in weight than most other variants of bricks. The holes or the pores present in these bricks help in reducing their weight making them extremely lightweight.
What are advantages and disadvantages of hollow blocks?
Advantages Of Hollow Bricks:
- Strength & Durability: Hollow bricks are durable, having high compressive strength (3.5 N/mm2).
- Lightweight: Due to having hollow space, these bricks are lighter in weight than solid bricks.
- Electrical Installation:
- Sound Insulation:
- Fire Resistance:
- Mortar Consumption:
What are the advantages of hollow blocks?
8 Advantages of Concrete Hollow Blocks Construction
- Highly Durable.
- Better Insulation Properties.
- Environmentally Friendly.
- Cost-Efficient.
- Low Maintenance.
- Conserves Space.
- Bonding of Mortar and Plaster.
Why are hollow blocks hollow?
As hollow blocks have holes and because of the air in the hole of the block, it does not allow heat or cold in or out of the building. Hollow blocks are insulated against heat, wetness, and sound. Hollow blocks keep the house cool in summer and warm in winter.
Why are hollow blocks preferred to solid blocks?
Advantages of Hollow Blocks Over Solid Blocks: Hollow blocks are light in weight thus dead load on structure is less thus consumption of steel per sq. The cost of production of hollow block per unit is low as the raw materials consumed for a same sized block will be less as compared to a solid block.
What are the characteristics of AAC blocks?
1. 2. AAC stands for autoclaved aerated concrete block. The bricks taht is perforated is known as hollow bricks like porotherm bricks. 3. AAC blocks are grey in color. These bricks are red in color and other. 4. These blocks are uniform shape and size with sharp edges. These blocks are uniform shape and size with sharp edges.
What are AAC bricks?
AAC bricks are in high demand, owing to their high strength, load-bearing and thermal insulation properties. In the early 1920s, Dr Johan Axel Erikkson, along with Professor Henrik Kreuger, developed AAC blocks. After patenting the manufacturing process in 1924, AAC blocks were produced in full swing from 1929 in Sweden.
What is the effect of earthquake on AAC blocks?
The effect of earthquake is proportional to the weight of the structure. AAC blocks being a lightweight subdues any damage by quakes or high winds largely. MC blocks have a microscopic cellular structure of aerated pores, which has less water absorption property than regular bricks. Hence, building built by AAC blocks almost 80 \% water-resistant.
Do AAC blocks crack after installing?
AAC Blocks are known to crack after installation, which can be avoided by reducing the strength of the mortar and ensuring the blocks are thy during and after installation. They need to be handled more carefully than clay bricks to avoid breakage.
