Sleve analysis on a dry soil sample of mass 1000 g showed that 980 g 270 g of soil pass 4.75 mm and 0.075 mm sieve respectively. The LL=40% & PL=18% . The soil classification

Based on the sieve analysis data provided, we can classify the soil according to the Unified Soil Classification System (USCS).Here's the breakdown of the data:- Mass of dry soil sample: 1000 g- Mass of soil passing 4.75 mm sieve: 270 g- Mass of soil passing 0.075 mm sieve: 980 gTo classify the soil, we need to calculate the percentage of soil passing each sieve size.1. Calculate the percentage of soil passing the 4.75 mm sieve: 2. Calculate the percentage of soil passing the 0.075 mm sieve: Now, we can use these percentages to classify the soil according to the USCS. The soil is classified based on the percentage of soil passing the 4.75 mm and 0.075 mm sieves.- If the percentage passing the 4.75 mm sieve is less than 5%, the soil is classified as gravel.- If the percentage passing the 4.75 mm sieve is between 5% and 37.5%, the soil is classified as sand.- If the percentage passing the 4.75 mm sieve is between 37.5% and 75%, the soil is classified as silt.- If the percentage passing the 4.75 mm sieve is greater than 75%, the soil is classified as clay.In this case, the percentage passing the 4.75 mm sieve is 27%, which falls within the range for sand. Therefore, the soil is classified as sand.Additionally, the liquid limit (LL) and plastic limit (PL) are given as 40% and 18%, respectively. These values help to further characterize the soil's plasticity.So, the soil classification based on the provided data is **sand**.
