Abstract:

This study is aiming in recycling the construction wastes in an experimental way in order to save the environment and to produce ferrocement bricks with good properties. The experimental program including production of ferrocement bricks by partially replacing cement with 30% fly ash; and 50% of coarse aggregates with recycled concrete wastes (RCA) and recycled clay bricks (RBA). About 96 samples with different mix proportions were produced; half of them were strengthen with a mesh. The tests were compressive strength, density, absorption and durability of brick against chloride effect; they tested after 7, 14 and 28 days of curing under ambient temperature.
The results indicates that compressive strength is decreasing by adding the waste aggregates but RCA gives better behavior by reduction of 30% than control sample with mesh and 23% than control samples without mesh. Based on this investigation; it was discovered that the best result was to produce ferrocement bricks with mesh replacing the cement with fly ash (30%) as well as replacing the coarse aggregate by 50% of recycled concrete as it will protect environment against wastes and reducing CO2 emision by reducing cement consumption. Mean while; this ferrocement brick is durable and lighter in density.

Keywords:
