Abstract


The bricks are made from a mixture of soil and water. In this study, the brick-making process will
try to mix the soil with additives (additive) which is fly ash brick (fly ash) to determine how much
benefit the waste of the additive materials and compare the compressive strength of ordinary brick
by brick that has been mixed with additive materials such as fly ash to achieve SNI specification
bricks that’s strong and durable.
Soil sample used is a type of clay that comes from the village Yoso Mulyo, Metro. Additive
materials used are fly ash from power plants Tarahan. The variation of dimension used are 4cm x
4cm x 4cm, 5cm x 5cm x 5cm, 6cm x 6cm x 6cm, 7cm x 7cm x 7cm. On dimension of 7 cm x 7 cmx
7 cm the average compressive strength value is 58,46 cm 2 this is the best compressive
strength.Thus testing the bricks that have been made through the process of mixing, curing and
burning, do include specific gravity test compressive strength and water absorption test. Based on
the results of physical testing of the original soil, soil samples Unified system classifies as a fine-
grained soil and belongs to the group ML
The results showed that the brick-making post-combustion by using the addition of fly ash as an
additive in a mixture of brick-making material effect on the addition of compressive strength
values, so that the power on brick obtained in this study is quite good and meet established
standards of the National Standardization Agency for Indonesia (BSNI). The high value of the
compressive strength of the brick using fly ash additive materials due to reduced air volume and
pore cavities in the soil particles are filled.
Keywords: bricks, fly ash additive, compressive strength
