Abstract

In Malaysia, coal is one of the energy resources. The requirements was predicted to be more than
22.5 million tons of coal utilized in 2010, which resulted in a large volumes of coal ash are
produced as waste material. The utilization of Pulverized Fuel Ash (PFA) as a cement
replacement in concert mixes has found high attention through the last few years. This study is
based on laboratory works including determination of the optimum mix design which will lead to
optimum compressive strength, water absorption and initial rate of suction of soil-cement bricks
enhanced with (PFA).The replacement of some of the Portland cement offers greater potential as
a method of reducing environmental impact. The experimental results showed that the Initial
Rate of Suction of the bricks increases as the amount of the PFA increases till a certain limit and
then start decreasing, that limit is when brick became durable because all the pores inside the
brick are filled with PFA hence it will decrease the penetration of the water. According to the
results of the 0%, 10%, 20% and 30% PFA the average compressive strength of soil-cement
interlocking bricks with mortar fill was around 13.52, 9.42, 9.86 and 7.81 N/mm2 respectively,
which illustrates that based on BS 3921 the interlocking brick unit, all can be classified as load
bearing bricks class 1. It is found that soil-cement interlocking bricks containing up to 20% PFA
is viable to be used as load bearing wall.
