What kind of blocks are used to build a house?
Concrete block has been used as a building material for more than a century. In some regions, concrete block is also a common building material frequently used in home construction. Generally, concrete blocks are fabricated using products such as Portland cement, different aggregates such as stone or quartz, and water.
What is an aggregate block?
Aggregate blocks are building blocks designed with dense aggregate to create durable longer lasting concrete blocks that are used as concrete building blocks in many different types of building applications across multiple types of projects from housing and commercial buildings to industrial construction.
What aggregate is used in concrete blocks?
Ultra-lightweight and lightweight blocks are manufactured from cement together with one of a variety of natural or man-made expanded aggregates including: granulated/foamed blast-furnace slag, expanded clay or shale, furnace bottom ash (FBA) and fly ash (FA).
Which is better bricks or concrete blocks?
3. Durability: Red traditional bricks are known to be more durable and the structures made from them are stronger than the ones made from hollow blocks.
What blocks for external walls?
Aerated concrete or ‘aircrete’ block.
Are concrete blocks better than bricks?
Block walls have higher density as compared to brick constructions and hence they offer more soundproofing.
Which is better concrete blocks or concrete masonry units?
Concrete block masonry which is also known as concrete masonry unit (CMU) have advantages over brick and stone masonry. The cement-aggregate ratio in concrete blocks is 1:6. Aggregate used is of 60% fine aggregate and 40% coarse aggregate. Their Minimum strength is about 3N/mm 2. ASTM C-90-91 specifies the compressive strength requirements
What are the dimensions of a masonry block?
Masonry blocks are produced in rational sizes for ease, speed and flexibility of construction. Can be laid to a 450mm module achieving wall tie positions, window and door heights. Masonry blocks are cast in a unique ‘T’ shape, with false joints, so they appear to be made of several individual stones
How big are concrete blocks used in construction?
Types of Concrete Blocks or Concrete Masonry Units Used in Construction. Concrete blocks are manufactured in required shape and sizes and these may be solid or hollow blocks. The common size of concrete blocks is 39cm x 19cm x (30cm or 20 cm or 10cm) or 2 inch, 4 inch, 6 inch, 8 inch, 10 inch and 12-inch unit configurations.
What is the cement-aggregate ratio in concrete blocks?
The cement-aggregate ratio in concrete blocks is 1:6. Aggregate used is of 60% fine aggregate and 40% coarse aggregate. Their Minimum strength is about 3N/mm 2.
