  • Analysis of Aggregates By Image Processing Using Matlab

    heavily depend on the shape of aggregate particles. In recent years, image analysis is widely used to analyze the particle shape characteristics of aggregate. In this research, shape properties of coarse aggregates are compared using image analysis by determining the shape characteristics of aggregate such as elongation,

  • Sieve Analysis of Aggregates Civil Engineering

    Sieve analysis helps to determine the particle size distribution of the coarse and fine aggregates.This is done by sieving the aggregates as per IS: 2386 (Part I) – 1963. In this we use different sieves as standardized by the IS code and then pass aggregates through them and thus collect different sized particles left over different sieves.
