Effect of temperature on adhesion of clay soil to steel

Abstract

Soil adhesion is one of the important factors in measuring the amount of energy consumption. In this paper, the effect of temperature on the amount of clay soil adhesion was investigated. The soil used in this research was saturated clay mud. In order to measure adhesion, a specific instrument was designed. The dimensions of the metal plate were 210×70×20 mm and its weight was 2.5 kgf. The metal plate alloy was st37. The adhesion was calculated from the difference between weight of water used for clearing the metal plate of the soil and the weight of the metal plate. Six levels of temperature from 5 to 30°c were applied. A refrigerator and an oven were used for getting the required temperature. The test was performed three times for each level. Results showed that an increase in temperature from 5 to 30°c decreases the soil adhesion. Three equations such as linear polynomial, exponential and quadratic polynomial correlated with the experimental data and the result showed that the quadratic polynomial model had the best correlation with experimental data.
