So greater the surface area, stronger the surface charge and greater will be the amount of absorbed water, therefore higher will be the liquid limit. Some clay minerals have larger surface area and clay particles have negatively charged surface.
The liquid limit of the soil depends upon the clay mineral present in it. And also stops flowing like a liquid.Īt that point shearing strength of the soil is the smallest value that can be measured in the laboratory. We learned liquid limit as the water content of the soil at which it changes its state from being liquid to plastic and stops being liquid. We have learned that Consistency is a term which is used to describe the degree of firmness of soil and consistency limits are water content of soil at which the soil changes from one state to other.
