PENGARUH PENAMBAHAN ABU SEKAM PADI DAN ABU TERBANG BATUBARA TERHADAP KEKUATAN TEKAN DAN POROSITAS GENTENG TANAH LIAT KABUPATEN PRINGSEWU
Abstract: Rice husk ash and
prosperous coal fly ash silica (SiO2). Silica-term construction, concrete
technology has been used primarily as an
additive. Husk ash and coal fly ash is used as an additive clay roof tile
manufacturing process. It is made by compounding of clay, sand, water and husk
ash. Then, they are mashed by extruder machine and forming of kuweh and then,
airing for three days before the process of stamping. The roof tile is dried
for four days then there is fumigation for twelve days and continued by
combustion for also twelve days. The examination which used is press and
porosity examination with the aim of knowing whether there is additional impact
of rice’ husk ash’ existence or not into clay roof tile in Kabupaten Pringsewu.
The research’s results showed that there is conversion of press and porosity
power compared with roof tile rice’s husk ash composition. The optimum value
for the press and examination of porosity obtained from the tile with a
composition of 5% rice husk ash and 5% coal fly ash 'with an average of 12.253
KPa press strength and porosity values average value of 18.06%. The minimum
value for the press obtained from the tile with a composition of 5% rice husk
ash and 2,5% coal fly ash with the press power’s average value 9.757 KPa. The
minimum value for porosity from the tile with a composition of 5% rice husk ash
and 7,5% coal fly ash with the porosity average value 23.78%.
