Fly ash brick (FAB) is a building material, specifically masonry units, containing class C or class F fly ash and water. Compressed at 28 MPa (272 atm) and cured for 24 hours in a 66 D.C. steam bath, then toughened with an air entrainment agent, the bricks last for more than 100 freeze-thaw cycles. Owing to the high concentration of calcium oxide in class C fly ash, the brick is described as "self-cementing". The manufacturing method saves energy, reduces mercury pollution, and costs 20% less than traditional clay brick manufacturing.
As the name suggests brick lock itself with other bricks and it is these interlocks which give strength to wall.
No cement mixture is needed for bonding.
90% of cement and 90% sand ,even usage of water is saved with this interlocking technique.
Weight of interlocking bricks is more than normal conventional baked bricks.
The interlocking tiles are a high thickness product, which, thanks to their strength, are resistant to any type of vehicle. Their principal characteristic is that, unlike standard tiles, they are not glued to the floor, but simply laid down and kept firm by compacted sand inserted under the pavers and in the gap between the pavers, thanks to distancing notches the interlocking pavers have on their sides. The standard thickness is 50-60 mm, but they can be made up to 80 mm thick.
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. A brick can be composed of clay-bearing soil, sand, and lime, or concrete materials. Bricks are produced in numerous classes, types, materials, and sizes which vary with region and time period, and are produced in bulk quantities. Two basic categories of bricks are fired and non-fired bricks.
We are often responsible for specifying, designing and manufacturing the materials with which they build their structures.
Studies in construction materials are intended to make structural, transportation and foundation engineers aware of the fundamental properties of the materials they use.
