Determine batch quantities of aggregate and $-5\mathrm{.}0mm),$ cement and water required to carry out a moisture$-$density test.

Assume that a sample size of $2500g($mass of oven$-$dry aggregate and cement$)$ will be required for each individual specimen.

Use moisture contents of $4,6,8,10$ and $12\%.$
