THE EFFECT OF CHEMICAL WETTING AGENTS ON THE COMPACTION OF CLAY AND SILT SOILS.
Abstract
Test results for the four categories of admixtures tested (amphoteric, anionic, cationic and nonionic) showed that increases in percentage of admixture of all surfactants caused an increase in density of the clay soil. The most effective surfactants were the anionic and nonionic types and the least effective were the cationic and amphoteric types. The largest increase in density occurred at percentage admixtures between 0.25 and 0.50 per cent. The average increase at these percentages was 9.0 per cent. Increased percentages of admixture above 0.50 per cent caused diminishing increases in density in all cases. The silty soil was quite insensitive to the addition of the surfactants to the compaction moisture. Increases in the percentage of admixture caused the density to decrease when the cationic and amphoteric surfactants were used. The maximum decrease was 3 per cent and occurred at a 3 per cent concentration of surfactant. The anionic and nonionic surfactants caused an increase in density of 2 per cent at a percentage admixture of 3 per cent. The largest increase or decrease in density occurred at a percentage admixture between 0.25 and 0.50 percent.
