SOIL STABILISATION WITH FLY ASH

OSOBENNOSTI TEKHNOLOGII UKREPLENIYA GRUNTOV ZOLAMI UNOSA

The paper is a summary of laboratory and full scale studies concerning the development of a soil stabilisation technique for sand (uniform), gravel and silt using fly ash (about 20%) containing 6 to 22% of free lime, 4 to 17% of calcium sulphates and having a specific surface of 1100 to 4300 cm2/g. In order to avoid swelling (which can reach 40% in volume) of soils stabilised with fly ash, the mixtures are compacted at least 4 days after having been maintained at a water content 2% higher than optimum. The results are comparable to those obtained with cement treatment; the method is cheaper. (TRRL)
