What is syntax for String concatenation?

I have $1 as directory.
$var is some variable value
'/' String value.

How do I have to concatenate if I have to run utility -

util $1 followed by '/' followed by $var

There is no space between these three.

$ x.sh "/apps/opt" "/informix"

$ export file1="informix"
$ x.sh "/apps/opt" "/$file1"
/apps/opt/informix
$ x.sh "/apps/opt" "$file1"
/apps/optinformix
$ x.sh "/apps/opt" "/$file1"
