Each building or structure will require the use of different types of blocks. The kind of block chosen for each project will vary depending on its load-bearing characteristics, appearance, density, weight and thermal properties. The three main types of block are Dense, Aerated and Lightweight.
Dense Blocks are usually made from cement, coarse aggregate and fine aggregate. These blocks are very strong and are often used for structural purposes. They make an excellent choice for load-bearing walls and foundations.
These dense blocks have good thermal mass, helping to keep buildings cool in summer and warm in winter.
Aerated Blocks are made from cement, lime, pulverised fuel ash, and sand. They are convenient to work with as they are reasonably lightweight and easy to cut.
They have a closed-cell structure, which makes these blocks more water-resistant. They also have good thermal insulation properties and can protect against fire.
Lightweight Blocks are easy to handle but are a little pricier than dense blocks. They are produced from cement mixed with a variety of natural or artificial expanded aggregates. They can be used for external and internal walls, especially where loading is restricted.
