Characterization of manufactured sand: Particle shape, surface
Crushed limestone with two particle size grades, i.e. 10–25 mm and 5–10 mm were used, the particle size distribution is listed in Table 3, its crushing value is 18.6%, and the apparent density is 2720 kg/m 3. Nine kinds of fine aggregates were used in this experimental investigation, i.e. The characterization of particle shapeCrushed rocks of all types; Talus; Crushed slag; 4. Flaky and Elongated Aggregate. Flaky shape of aggregate is when the thickness of aggregate is much less than the length and breadth of the aggregate. Flaky Aggregate: When the least dimension is less than 3/5 th of its mean dimension, the particle is called flaky aggregate.4 Types Of Aggregate Based On Shape Civil Giant

Also, for comparing the aggregate shape parameters, the statistical analysis, Student’s T-test, is conducted. Student’s T-test is a common technique for compares means and standard deviations for two groups of cases [44]. Also, Student’s t-test was used for comparing aggregate shape produced different crushers by Rajan and Aggregate shape characteristics have been classified as rounded, irregular or partly rounded, angular, and flaky as per IS-383:1970 (reaffirmed-2002) .
