Characteristics of Bamboo Leaf Ash Blended Cement Paste and Mortar
Abstract: The use of bamboo
leaf ash as cement supplement can contribute to reduction in cost and
environmental hazard associated with cement production as well as waste
pollution caused by the littered bamboo leaves. Therefore, the characteristics
of cement paste and mortar incorporating bamboo leaf ash were investigated. The
results of the physical properties of the pastes were within the requirements
stipulated by relevant standards while that of the mortar cubes indicated that
the compressive strength generally increased with curing age, and that the mix
containing 15% Bamboo Leaf Ash (BLA) by mass competes favorably with that of
the reference mix at 28days and above. The water absorption and apparent
porosity were observed to increase with increase in BLA content, while the bulk
density decreases as the percentage of BLA increases from 5% to 25% by mass.
The study concluded that 15% BLA replacing cement is adequate for the
production of masonry mortar.
