CEMENTITIOUS STABILIZATION - TRID

CEMENTITIOUS STABILIZATION. The principal materials used for the cementitious stabilization and modification of highway pavement materials are lime, fly ash, and portland cement. Whereas lime and portland cement are manufactured products, fly ash is a by-product. As a consequence, fly ash generally exhibits greater variability than is seen in ...

STABILIZATION AND SOLIDIFICATION OF

Practical stabilization and solidification of soils and sludges exhibiting contamination from heavy metals or organic compounds can be accomplished using readily available, conventional, or byproduct cementitious (hydraulic or pozzolanic) materials, such as portland cement, slag cement, cement kiln dust, lime kiln dust, hydrated lime, and fly ash.

STABILIZATION OF SULFATE-CONTAINING SOIL BY

STABILIZATION OF SULFATE-CONTAINING SOIL BY CEMENTITIOUS MIXTURES MECHANICAL PROPERTIES. Winn Rock (CaSO4) gravel from a quarry in Winn Parish in north Louisiana was used extensively as a surface course for local parish roads. Stabilization of these roads with Type I portland cement followed by an overlay of asphaltic concrete resulted in heaving.

Applications of Soil and Cement Chemistry to

Stabilization and solidification have been defined as follows (3,8): Stabilization refers to those techniques that reduce the hazard potential of a waste by converting the contaminants into a less soluble, mobile, or toxic form. The physical nature and handling characteristics of the waste are not necessarily changed by stabilization.
