Our Case
  • 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.

It contained primarily augite, feldspar minerals, and plagioclase (Sun, Indraratna, & Nimbalkar, 2014).The physical attributes of the ballast were evaluated by standard testing procedures according to AS 2758.7 (1996) and can be found in Indraratna et al. (1998).
