ABSTRACT
Bricks are the most ancient and most
recognized building materials. Composite bricks are made by mixing two or more
building construction materials. This study compares the production of
48.14MPa, water absorption with 24hrs reveals of composite from sawdust and
clay using cement as a binding agent. A total of 16 bricks were made in the
wood science workshop unit ofthe Forestry and Environmental Management
Department in Michael Okpara University of Agriculture, Umudike (MOUAU), Abia
State, Nigeria based on the weight ratio ofsawdust to clay to cement was
(10,40&50kg) at a ratio of (1:4:5). Mass was measured using weighing
balance and density calculated from the mass and volume of the bricks. Findings
reveal that sawdust is a very good lightweight construction of bricks with good
water absorption (WA) and strength characteristics. The composites were tested
for compressive strength (CS) using the universal testing machine as the crack
due to compression. The mean CS value was highest at clay/cement composite
bricks at 77.83MPa &lowest at sawdust mix composite bricks at concrete
sawdust composite bricks & mixed sawdust composite bricks have the highest
WA than other building materials. Results on the chemical composition of
sawdust reveal mixed sawdust was high in cellulose, hemicellulose & lignin
at the mean value of 34.99,21,35&47.68 respectively. In conclusion,
increased utilization of sawdust composite in brick construction will mitigate
against potential sawdust environmental pollution, conserve energy, and reduce
disposal costs. The composite bricks from sawdust & clay will be useful and
provide a sustainable solution.
