Manufacturing of fly-ash bricks are the very useful alternatives of conventional burnt clay bricks. Manufacturing of clay bricks
cause top soil removal, environmental pollution and health problems. To avoid all this environmental threats an attempt is made
to manufacture of bricks using fly-ash, gypsum, sand and cement. Mainly fly-ash bricks are made by applying compressive load on
the mold. In this research, the effect of brick forming load on the crushing load, water absorption and unit volume weight were
studied. For this purpose bricks were prepared for different fly-ash (50% to 65% at 5% increments), gypsum (12% to 3% at 3%
decrements), sand (28% to 22% at 2% decrements) and 10% cement. All ingredients were thoroughly mixed and then poured
them to a mold of 9.5cm x 4.5cm x 2.75cm. Bricks were made by different forming load and mechanical properties were noted. This
research suggested that it was possible to make good quality bricks using fly-ash, gypsum, sand and cement.
