| Summary: |
This paper presents an experimental study on the development of masonry block with Palm Oil Fuel Ash
(POFA) as a partial replacement to cement whilst maintaining satisfactory properties of masonry block.
The dosages of POFA are limited to 0%, 20%, 40% and 60% by mass of the total cementitious material in the
masonry block. The experiments on masonry block investigate the compressive strength and the
breaking load for mechanical properties and water absorption and efflorescence for its durability. The
compressive strength and the breaking load of the masonry blocks reduce with increasing percentage of
POFA replacement. However, it satisfies the requirements of Class 1 and Class 2 load-bearing masonry
block according to Malaysian Standard MS76:1972. In terms of durability of the masonry block, water
absorption for all the masonry blocks satisfies the requirement of ASTM C55-11 and there is no any sign
of efflorescence on all the masonry blocks. POFA based masonry block are also found to be cheaper than
the cement sand masonry blocks. The experimental studies indicate that POFA based masonry block has
a significant potential for application in the construction industry.
