Assume the specific weight of the aggregate sample given below is $(2\mathrm{.}80-0\mathrm{.}02$n$)$ kg$/$dm $.$ Unit

$3$

weight is $(1\mathrm{.}50+0\mathrm{.}02$n$)$ kg$/$dm $.$ Design a concrete mixture by using below given aggregate

$3$

sample. Concrete grading will be C$30,$ specific weight of cement is $31\mathrm{.}5$ kg$/$dm $,$ Cement is

P$32\mathrm{.}5,$ vibrator will be used during the placing but the mixing could not be controlled well.
