Bricks & Blocks

A brick is building material used to make walls, pavements and other elements in masonry construction. Traditionally, the term brick referred to a unit composed of clay, but it is now used to denote any rectangular units laid in mortar



Concrete Bricks

Concrete bricks are mixtures of cement, sand and aggregates vibrated in moulds and steam cured.






Hollow Blocks

Hollow and dense cement concrete blocks are known as Concrete Masonry Blocks (CMB). These have been developed as an alternative to bricks. These Blocks are widely used in construction activity. The hollow blocks are made of cement, stone chips, stone dust and sand are not only cheaper than bricks but have other specialties as well.

Types of Bricks
Types of Bricks used in Masonry

  • Common Burnt Clay Bricks
  • Sand Lime Bricks (Calcium Silicate Bricks)
  • Concrete Bricks
  • Fly ash Clay Bricks
  • Fire Clay Bricks

    • Common Burnt Clay Bricks are fired bricks. These are formed by pressing in moulds or by an extrusion and wire cutting process. Then these bricks are dried and fired in a kiln.

    • Sand Lime Bricks (Calcium Silicate Bricks) are mixtures of sand and hydrated lime pressed in moulds and cured in a high-pressure steam autoclave.

    • Concrete Bricks are mixtures of cement, sand and aggregates vibrated in moulds and steam cured.

    • Fly Ash Clay Bricks are used along with clay in these bricks. Fly ash is obtained from boilers of thermal power stations.

    • Fire Clay Bricks exists at much depth below the surface and is usually mined. Generally, Fire clays contain metallic oxides less than surface clays and have more uniform chemical and physical properties.

Specifications of Bricks

Bricks should confirm specifications as per IS-1077-1992 and must be homogeneous in texture.

  • Made of good earth which is free from saline deposits and are sand molded.
  • Burnt thoroughly without being vitrified and have deep red, cherry and copper color.
  • Regular and uniform in shape and size with sharp and square edges and parallel faces.
  • Must be homogeneous in texture and emit a clear ringing sound on being struck together.
  • Free from flaws, cracks, chops, stones and lime.
  • Should not absorb water more than 20% of its own dry weight after 24 hours’ immersion in cold water.
  • Have a minimum crushing strength of 105 kg per sq. cm when tested according to the test.
