$5-$ Design a concrete whose chemical analysis will be exposed to the chemical effect caused by the

groundwater given below.

Select the relevant impact class given in TS EN $206$ and calculate the amount of materials required for $1m^3$

of concrete with the assumption that the air content is $1\%.$

$2\mathrm{.}5\%$ super plasticizer was used to provide the desired workability.

When the chemical additives used at $2\mathrm{.}5\%,$ it will be considered to reduce $15\%$ water.

$($Relevant Tables for solution could be used from outsources such as Lecture notes etc.$)$

The physical properties and ratios of the aggregates to be used in the mixture are given below.
