| Abstract |
In the northeast of Thailand, raw material for fired-clay brick is obtained from fine
stream sediments in the lower Nam Phong and upper Chi River sub-watersheds. Hundreds of
brickyards are concentrated within the few square kilometers where the Nam Phong river merges
with the Chi River. These brickyards supply rice husk ash (RHA) construction bricks for the entire
northeast region. Technical study on the production of these bricks is currently limited, therefore,
detailed studies on mechanical and chemical properties will enhance the understanding of the
production process in order to improve their quality. The objective of this study is to investigate the
production process and determine the compressive strength of fired-clay bricks produced in this
industrial area. The study was conducted by preliminary investigation of the brickyards and
production process. Brick samples as well as raw sediment materials were collected from 6
randomly selected locations for laboratory testing on physical, chemical, and mechanical properties.
A total of 300 brick specimens were collected being 50 specimens from each location. The brick
dimensions are roughly 5×5×15 cm with an average weight of about 680 g. X-Ray Diffractometry
results show that the fired brick composition is approximately 90-98% quartz, 5-7% clay minerals,
and less than 1% minor minerals. Mechanical behavior of the fired-clay bricks was evaluated by
compressive loading of single brick units conducted under dry and submerged (with reverse
osmosis water) conditions. The compressive strength of the brick unit is found to be proportional to
its density with values in the range of about 0.4-1.2 MPa. Bricks with RHA to sediment ratio of 1:3
exhibit a higher average strength than that of other ratios. |
