PAVING STONE BERBAHAN ABU SAMPAH TANAMAN

Abstract

Abstract
This paper discusses about the advantage of organic disposal ash
as an additive on paving stone mixture. The organic disposals such as
leaves, wood stick, etc. were taken from garbage tank at the market,
living area, and temporary tank. Then they were burnt in to an artificial
furnace at temperature of 28-500°C for about 195 minutes. The mix
design were 1 portland cement: 3 sand: 3 stone ash: organic ash of
0%, 10%, 11%, 12%, 13%, 14% and 15% of cement weight: 0,6 water.
The result showed that organic disposal ash ratio was 0.05, and the
gradation was observed in zone III. The weight of paving stone
containing organic disposal ash was smaller than normally paving stone.
The more organic disposal ash the lighter weight of paving stone. The
compressive strength of paving stone containing 12% of plant ash was
the strongest, it was 119% of the control.
Key word: compressive strength, paving stone, organic disposal ash
