Are flyash bricks strong?
The strength of fly ash brick manufactured with the above compositions is ranges between 7.5 MPa and 10 MPa. Fly ash bricks are lighter and stronger than clay bricks.
Do fly ash bricks need plastering?
Uniform colour with pleasing appearance. Non uniform colour because the colour of these bricks depends on soil. Plastering is not required due to smooth finish.
How is fly ash bricks made?
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 °C steam bath, then toughened with an air entrainment agent, the bricks can last for more than 100 freeze-thaw cycles.
Is fly ash bricks good?
Fly ash bricks are hi-tech well-improved quality bricks used for construction of brick masonry structures. They are used as replacement for normal clay bricks and has better properties than it. The utilization of fly ash bricks results in conservation of natural resources as well as protection of environment.
