Mechanical Properties of Rice Husk Ash (Rha) Brick as Partial Replacement of Clay

Abstract: Clay has been used as main material in fabrication of bricks however the use of waste materials in brick manufacturing has been introduced for conservation of dwindling clay resources, as well as preventing environmental and ecological damages caused by quarrying and depletion of raw materials. Bricks that available in some regions have poor quality, low compressive strength, higher water absorption and uneven surfaces Therefore in this study, rice husk ash has been utilized for the preparation of bricks in pa… Show more

“…A 33% decrease and about 40% increase in the compressive strength and water absorption resulted respectively for the 14% RHA addition. However, the weight of the composite reduced with increased RHA [22]. Investigation on the compressive strength and water absorption for the addition of RH and RHA affirmed that lower quantity of RHA is beneficial while higher ones lead to deterioration.…”

“…22 Also, Lamaming et al 36 produced binderless particleboard with oil palm and analyzed the influence of oil palm chemical components on the manufactured board, and the binderless particleboard was evaluated through a series of mechanical, physical, and chemical analyses to assess the self-bonding mechanism. Other lignocellulosic materials that have been used to produce binderless boards include; coconut husk, 24 cotton stalk, 25 kenaf core, 26 rice straw, 37 oil palm, 30 papyrus fiber, 33 sugar cane bagasse, and sweet sorghum bagasse. 20,34 The preparation of binderless ramie stem particleboard by pressing using steam injection before hot pressing was carried out by Guo et al 38 The ramie binderless board was foremost hand-formed into a single layeredmat by using a mold box; it was then pressed with a sealed steam-injection press before undergoing the hot press at a temperature of 190 C, a pressure of 5 MPa, for a time of 10 minutes.…”

“…With the aforementioned introduction and facts, current study aims to produce and characterise amorphous silica (ASi) from the wheat straws using sol gel method and investigating its chemical characteristics for the various environmental applications compared to commercial amorphous silica (CSi). Since there are a few reports stating the utilization of wheat straws (Table 1) and higher content of silica in it (90.56%) [13], this would be a novel research in producing silica materials from it. The solutions were prepared using deionised water (Milli-Q).…”
