POZZOLAN EFFECT ON THE MECHANICAL PROPERTIES OF SCBA BLENDED CEMENT TREATED SOIL

Abstract

The recent agricultural and industrial waste reduction research has focused on monetary, sustainable environment, and technological considerations. Discarded raw materials such as rice husk ash, fly ash, coir fiber and silica fumes were widely explored and successfully utilized as blending elements for cement. Current studies have proved that Sugarcane Bagasse Ash (SCBA) produced from sugar production has a pozzolanic reaction due to the high substance of amorphous silica in this raw material. This research would boost the insight of potential blending agents that can reduce the cost and stabilize problematic soil. This study intends to evaluate the effect of SCBA blended cement on improved soil’s mechanical properties, including the shear strength and the compressibility of the treated soil. Unconfined Compressive Strength test was conducted to attain the compressive behavior, while the One-Dimensional test was performed to examine the compressibility behavior. The tested samples with SCBA show a beneficial effect in terms of both compressive strength and compressibility. This study proved that SCBA could be applied at least as a partial substitute to the Portland cement.
