Pengaruh Penambahan Abu Sekam Padi Terhadap Kekuatan Tekan Dan Porositas Genteng Tanah Liat Kabupaten Pringsewu
Abstract: Rice’ husk ash’
prosperous in silica (siO2). Silica in construction term, especially concrete
technology had already been used as additional ingredient. Husk ash is used as
additional ingredient of clay roof tile making 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 without rice’s
husk ash composition. The optimum value for the press and porosity examination
is obtained from the roof tile with 5% rice’s husk ash’ composition with the
press power’s average value 11.118 KPa and the porosity average value 20.16%.
The minimum value for the press and porosity power is obtained from the roof
tile without rice’s husk ash’s composition with the press power’s average value
8.393 KPa and its porosity average value 21.92%.
