Appendix (6) pH-measurement of natural soils and soil-lime, soil-fly ash, and soil-lime/fly ash mixtures to determine the optimum lime-, fly ash- and lime/fly ash-content for the studied soils. T= Temperature (°C), L% is the optimum lime content minus 2% in case of the tertiary clay and the weathered soil and is the optimum lime content minus 1% in case of the organic silt. The Blue numbers indicate to the optimum chemical additive content according to pH-test.
