In a liquid limit test relationship between water content (w) and number of blows required to close the groove (N) is obtained as w = 38.6066 - 4.0931n N. The plastic limit of the clay is 13%. Natural water content is 18%. Determine the liquid limit, plasticity index, liquidity index, relative consistency, flow index and toughness index of the soil. Also calculate activity number if percentage of clay is 36%.
