Compressive strength of brick in N/mm2 & kg/cm2 Civil Sir
Aug 24, 2020 Compressive strength/crushing strength of fly ash brick. Fly ash bricks are manufacturing by mixing Quarry Dust / River Sand,Stone aggregates less than 6mm in Size, Cement and Fly Ash ( Fly Ash quantity will be 10% to 20% of Cement ). Normally the actual cement quantity required will be replaced with 10% to 20% Fly Ash.

Fly ash brick Wikipedia
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. Owing to the high concentration of calcium oxide in class C fly ash, the brick is described

What is Fly Ash Brick? its advantages, and disadvantages
Jul 21, 2020 The compressive strength of fly ash bricks is very higher (9-10 N/mm2). Because of higher strength no breakages/wastages during transport and handling. The lower thickness of joints and plaster decrease cracking in plaster. These bricks do not cause any additional load for the design of structures and provide better earthquake resistance.

Fly ash Bricks: Properties, Advantages & Disadvantages
Introduction to fly ash bricks: Fly ash brick are environmentally friendly, manufactured by hydraulic pressure machines. They are 28% lighter than normal clay bricks and have a compressive strength greater than 40Mpa than normal bricks. They are inexpensive and eliminate the need for plaster, it can reduce high construction costs and soil erosion.

Fly Ash Bricks Advantages, Disadvantages & Manufacturing
Heavier than fly ash bricks. The compressive strength of fly ash brick is around 100 kg/cm2: The compressive strength of clay brick is around 35 kg/cm2. They can absorb more vibration than clay bricks. Cannot absorb heavy vibration. Stronger and denser than normal red bricks. Slightly less stronger. Less mortar requirement than clay brick
