Toughness index formula

WebTake log(no of blows) only for finding flow index or for finding liquid limit using a flow index value. If the graph is given and we want to find LL, then just do interpolate without taking the log of no of blows. Because we are plotting as such in semilog to get a straight line. ie, (70-20)/(100-10) = (LL-20)/(100-25). LL = 61.66. WebThe shrinkage index is directly proportional to the percentage of clay-size fraction present in the soil. It can be used as an indicator of clay. The toughness index is a measure of the shearing strength of the soil at the plastic limit. A high value of toughness index indicates a high percentage of colloidal clay containing mineral ...

WebWhat is the toughness index? Toughness index is defined as the ratio of plasticity index (IP) of the soil to the flow index (IF) of the soil. … This gives us an idea of shear strength of soil at its plastic limit. When toughness index is less than 1, the soil is said to be friable, which means it can be easily crushed at the plastic limit. WebAs it mentioned earlier the indices of I 5 , I 10 and I 20 are calculated as ratios of the area under the load-defection curve up to 3, 5.5 and 10.5 times the first crack deflection, … hemichordata acorn worms https://thebodyfitproject.com
