Abstract
Baggage ash is a fine residue collected from the burning of baggage in sugar factory. The production of baggage ash is growing according to production of sugar. Research about using of baggage ash is continually in progress. Baggage ash is a non cohesive material having small specific gravity that is relatively smaller than that of normal soil. When burned at 600O C, baggage ash is pozzolanic material (Wibowo, and Hatmoko, 2003), and therefore its engineering behavior can be improved by addition of cement. Some experimental studies on chemical stabilization of baggage ash has been done. Wibowo and Hatmoko (2001) carried out a research of additional baggage ash to concrete. The research indicated that additional of baggage ash improved the strength of concrete with significant values. Wibowo and Hatmoko ( 2003, 2004) made an equipment to burn the baggage ash to get the optimum temperature to be the best pozzolanic material. Hatmoko (2003) observed the additional of baggage ash to expansive clay. In this paper, an experimental study was undertaken to study the individual and combined effects of randomly oriented fiber inclusions and baggage ash-cement stabilized soil. Baggage ash was taken from Madukismo Yogyakarta sugar factory, and it was mixed with clay with different proportions. The geotechnical characteristic of baggage ash-soil specimen, and baggage ash-soil specimen containing 0.8 to 1% randomly oriented fiber inclusions was investigated. A set of unconfined compression tests were carried out on baggage – ash soil specimen prepared with 4% cement alone and also with 4% cement and 1% fiber with 7 days of curing time. The study indicates that cement stabilization increases the strength of baggage ash – soil specimens as well as the strength of baggage ash – cement soil specimen with fiber inclusions
