Abstract :
Researchers are endeavoring to extract supplementary cementing materials from different agarin product. Different
types of agarin by-products are being used as a source of fuel for brick kiln. The generated ash from brick kiln is
usually dumped in open fields that creates a myraid of health and environmental issues. In this paper, an experimental
study is conducted to utilize the dumped ash as a supplementary cementing material in concrete. In order to find
out the optimum proportion of cement replacement, we replace cement with brick kiln ash at the ratio of 0 to 12.5%
with an increment of 2.5%. Subsequently, the tests of compressive strength, tensile strength and water penetration
are conducted. It is found that the cement replaced at 5% is optimum. The compressive and tensile strength are
increased up to 5% and 5%, respectively. Moreover, concrete impermeability is found to be improved by 50% at 5%
replacement.
