| dc.description.abstract | The clay mineral composition is one of the factors that affect the physical properties of soil, and knowledge of it is required to promote a fuller understanding of the origin of these properties. The relation between the clay content and plastic and liquid limits of natural montmorillonitic and kaolitic soils and of artificial mixtures have been examine and compared. Clay soil, expansive soil has a special mineralogical characteristic which leads to swelling when expose to moisture change. This behavior is due to the presence of considerable amount of montmorillonite clay mineral. The liquid limit is by one point method is the water content, experience in percent, at which the soil change from a liquid state to plastic state and principally it is defined as the water content at which the soil pat cut using standard groove closes for about a distance of 13cm (1/2 in) at certain blows, for a good determination N should be between 20 and 31 blows and with a range of 15 to 41 blows allowable for classification purposes, of the liquid limit machine (casagrande Apparatus).The liquid limit of a soil highly depends upon the clay mineral present. Thus, this paper is mainly investigating the Evaluation of one point liquid limit test for expansive clay soils of Ethiopia. According, several data was taken from different thesis that was done before on different local places. The relation obtained from statistical analysis relationship has an R2 of 0.787 and it shown below. LL=Wn(N/25)0.104 The results of the statistical analysis show that good correlation does exist between the between liquid limit and moisture content of local clay expansive soil. | en_US |
