| The aim of this research was manufacturing bricks has good specifications and environment friendly as well benefit of agricultural wastes in production of bricks. The mixtures were content of: (1) different ratios of bagasse "SB" (5, 10, and 15%) with cement kiln dust "CKD" ,by-pass cement, (45, 40, and 35%), (2) constant ratios of cement "OPC" (21%), sand "S" (15%), fly ash "FA" (9%) and hydrated lime "HL" (5(٪ by weight. Fifty four pieces of bricks were manufacture, prepared on 6 sample groups, with 9 bricks in each group. Each 27 bricks were using different particle size: (1) small chops "SC" (≤ 2.8 mm) and (2) large chops "LC" (> 2.8 mm) with various dosages of SB contents ranging from 5, 10 and 15% were added. Samples were manually mixed and placed into pressing mold to completion pressure. Then, samples were leaved to dry in the air for 28 days. Some physical and mechanical properties were measurement for these bricks. The obtained data showed that acoustic insulation and expansion increase with increasing SB in mixture while bulk density decrease for both SC and LC. The maximum value of bulk density was 1.43 g/cm3 at ratio of 5% SB for SC, the minimum value was 1.17 g/cm3 at ratio of 15% SB for LC. The maximum value of expansion was 10.46% at ratio of 15% SB for LC; the minimum value was 1.99% at ratio of 5% SB for SC. Water absorption percentage decreases with increasing SB for SC and increases with increasing SB for LC. The maximum value of water absorption percentage was 29.09% at ratio of 10% SB for LC; the minimum value was 18.99% at ratio of 5% SB for LC. Ratio of 15% SB for SC was gave higher compression stresses "δc" (kN/cm2) at lower strains. The values of compression stresses "δc" at 15% SB for SC were 0.18, 0.48 and 1.03 kN/cm2 at strains of 0.102, 0.154 and 0.2, respectively. Bending momentum increases with increasing SB for both SC and LC. The maximum value of bending momentum was 93.75 KN.mm at ratio of 15% SB for SC; the minimum value was 62.5 KN.mm at ratio of 5% SB for LC. | ||||
