EFFECT OF THE TIME LAG BEFORE COMPACTION OF SOIL-CEMENT MIXTURES ON THE QUALITY OF SUCH MIXTURES

This paper refers to studies carried out on mixtures of soils stabilized with portland cement, using two soils, one of which consists of sandy silt while the other is third-horizon soil. The primary purpose of the above-mentioned studies is to determine the effect on the quality of the mixture of the time lag between the addition of the cement to the soil and the final compaction. For this purpose two criteria are employed, one allowing the mixture to stand undisturbed for lengths of time varying from zero to six hours before compaction, while the other criterion calls for remixing the soils for one minute at intervals of fifteen minutes during the time the mixture stands. Cylindrical test specimens were prepared from the above-mentioned mixtures, and tested at simple compression for durability. They were cured in moisture chambers during periods of from seven to twenty-eight days, and tested for two conditions of moisture, one as they were withdrawn from the chamber and the other after immersion in water for one hour before the test. The effect of the moisture content on the quality of the prepared mixtures was analyzed. The effect of the variation in humidity and in compaction density on the strength of the test specimens at simple compression was also tested. /Author/
