QUESTION $1$

$1\mathrm{.}1.$ Explain the difference between the residual soils and transported soils.

$1\mathrm{.}2.$ The physical characterization of aggregate plays an important role in concrete mixtures as it determines its suitability for use in concrete. Explain the purpose of the following tests for concrete applications.

$1\mathrm{.}2\mathrm{.}1.$ Sieve analysis test on coarse and fine aggregates.

$1\mathrm{.}2\mathrm{.}2.$ Flakiness index $($particle shape$)$ on coarse aggregates.

$1\mathrm{.}2\mathrm{.}3.$ Compacted bulk density of coarse aggregates.

$1\mathrm{.}2\mathrm{.}4.$ Relative density of coarse and fine aggregates.

$1\mathrm{.}3.$ Table $1$ presents the laboratory test results for the Sieve Analysis and Atterberg limits $($Liquid Limit and Plastic Limit$).$
