sieve analysis for sand and surface area relation with angle of internal friction from sieve analysis test for granular soils we can drow surface area of sample instead of log diamter of particles curve and then we can essitmiet the surfce area for sample cm2\gm and from thise number we can classfied the sample and also from thise curve we can obtain the equflient sample have the same wieght and surface area and all particles of thise sample have same diameter called equvlant diamter then and from thise curve we can drow mohr cricle and drow tangent then obtain angle of internal friction
