PENGARUH PENAMBAHAN LIMBAH ABU SEKAM PADI TERHADAP KUAT TEKAN PAVING BLOCK DENGAN PENAMBAHAN ADMIXTURE SILICA FUME

---

Silica fume and rice husk ash are among the residual materials or waste, which
have not been optimally utilized, both by society and industry. Meanwhile, paving
blocks are still widely used as building materials. Until now, the use of paving
blocks still raises environmental issues. Therefore, this research aims to create
alternative paving blocks that are more environmentally friendly, utilizing silica
fume (SF) and rice husk ash. Silica fume is a by-product of the ferrosilicon or
silicon alloy production process in the metal industry. This process involves
heating silicon ore with carbon in a high furnace, which produces liquid silicon
and silicon dioxide (SiO₂). Silicon dioxide is then oxidized into very fine silica
particles, known as silica fume. Silica fume has high added value due to its
content of very fine and reactive silica particles, which can significantly improve
the properties of concrete or paving blocks. The quality of paving blocks is
determined by compressive strength testing. This study was designed with a
cement and sand aggregate mixture ratio of 1:4, silica fume variations of 5%,
7.5%, 10%, 12.5%, 15%, and the addition of 10% rice husk ash with mold
dimensions of 10 cm length, 10 cm width, and 6 cm height/thickness. The
dependent variable is the compressive strength value referring to SNI 03-0691-
1996. The results showed that paving blocks using silica fume increased
compressive strength values at the 5% variation, reaching 18.16 MPa. Based on
testing and comparison with SNI 03-0691-1996, the paving blocks in this study
still meet quality standard B as specified.
