Abstract
In general, fly ash (a by-product from the burning of coal in the electric power plants) is currently in
use for soil stabilization in some countries like USA, Japan, Scandinavian countries, India, and some
other countries and has several mendations and regulations. In Germany, however, fly ash is not
used for soil-stabilization. The present study is an attempt to estimate how the use of fly ash (from a
local electric power plant at Lippendorf, South of Leipzig city, Saxony, Germany), hydrated lime, and
lime/fly ash could improve the geotechnical properties [including consistency limits, compaction
properties, pressive strength (qu), elasticity modulus (Esecant), durability, California
bearing ratio (CBR), indirect tensile strength (σt), and the hydraulic conductivity (K-value)] of three
different soft fine-grained soils [tertiary clay, organic silt, and weathered soil] collected from Halle-
city region, Saxony-Anhalt, Germany. One of the most significant objectives of the present study is to
use the ultrasonic p-wave velocity testing as non-destructive method to e
