Measured and Predicted Five-Year Behavior of Soil-Mixed Stabilized/Solidified Contaminated Ground
In April 1995, a site in West Drayton near Heathrow Airport in the UK was treated by in-situ stabilisation/solidification using cement-based grouts and implemented using a soil mixing auger. The site was cored at 2 months and then at 4.5 years after treatment and samples were tested for various physical and chemical properties. These included strength, leachability, leachate pH, permeability, freeze-thaw and wet-dry durability and microstructural analyses. The time-related performance over a five-year period has therefore been established. In addition, research work is being carried out to develop accelerated ageing methods to enable the correlation between real-time and accelerate-time behaviour to simulate the much longer-term performance. Two methods are being considered namely elevated temperatures and accelerated carbonation. In this paper the five-year performance of three soil grout mixes is presented and the feasibility of the two accelerated ageing methods is assessed.
