...STRENGTH CHARACTERISTICS OF CEMENT TREATED CLAYEY AND SANDY SOILS IN TERMS OF OVERCONSOLIDATION RATIO K. KASAMA1 & K. ZEN2 ABSTRACT The subject of this study is a cement treated soil, which is cement mixed soil. The cement treated soil has a number of advantages, for instance, the strength becomes...

... shearing stress level which is explained by macroporosity. Critical ratio sand: clay = 5 : 1 was found when the increase of sand contents did not affect the behaviour. Chemical improvement was modelled by mixing sand with portland cement (2 % to 8 % by weight). A bonding surface was defined. The extent...

... ABSTRACT: A solidification method by cement of dredged sludge has been performed in laboratory during these last three years. The treated sludge is contaminated by heavy metals. The objective of the research program was to assess the possibility of treating and reusing the solidified sludge...

... it may be more suited to use as selected granular fill or sub-base. In particular, cement stabilisation will reduce frost susceptibility and may be a particularly appropriate outlet for burnt colliery spoil for use as sub-base. However, an increase in control and testing may be required, having an effect...

The consolidation method produces very homogeneous rock samples. The rock properties are well-defined and can be varied...
