Abstract

Lime materials [C^ sub a^ CO^ sub 3^ and C^ sub a^(OH)^ sub 2^] had been used since years ago as stabilization materials for clay soil. For peat soil, however, was only recently developed and it was found that the lime material had to be mixed with pozolon such as Fly Ash (FA) or Rice Hush Ash (RHA) as silica material; it was because peat had no silica content. This paper presents the use of two different types of lime [C^ sub a^ CO^ sub 3^ and C^ sub a^(OH)^ sub 2^] mixed with Fly Ash (FA) as admixture materials, those were, Admixture-1 [30% C^ sub a^ CO^ sub 3^ dan 70% FA] and Admixture-2 [10% C^ sub a^(OH)^ sub 2^ dan 90% FA]. Fibrous peat soil taken from Palangkaraya, Central Kalimantan, Indonesia, was stabilized with Admixture-1 and Admixture-2 separately, and then cured in different period of time in order to see the effect of each admixture to the peat behaviour. The result shows that both …
