dc.description.abstract | Nowadays, roof-tiles are largely used as one of the common building materials. In contrary Lapindo mud, which
keeps growing each day, need to be thought on its advantages. Therefore many researches caught this phenomenon and
tried to find out the correlation between Lapindo mud and roof-tiles material. As results, previous studies proved that
there are possibilities to apply Lapindo mud into ceramics material mix, as well as into ceramic roof-tiles material with
appropriate strength values. Advance studies on the effect of the Lapindo mud use to the equality of roof-tiles based on
SNI 03-2095-1998 and PGKI NI-19 provided many information on its effects against: roof-tiles, roof-tiles weight, rooftiles
cracks, roof-tiles dot percentages, roof-tiles flatness, its form-sizes, as well as its absorption. Furthermore, the
perfect mix of Lapindo mud on producing roof-tiles will give advantages on increasing strength and increasing
impermeable values. While on the other hand, too much Lapindo mud compositions will produce on deformation and the
increasing amount of cracks and dots. As mentioned before, a high-quality of ceramic roof-tiles can be achieved from a
perfect mix of Lapindo mud. Therefore further researches are needed to investigate the optimum compositions of Lapindo
mud, in order to produce a high quality of Lapido ceramic roof-tiles. | en_US |
