Yes, it is possible to put cement in between pavers when installing them, but it is not generally recommended. Cement is often too thick for pavers and can cause them to shift or become uneven over time. Moreover, paver sand, the commonly used product for in-between paver spaces, is much easier to use and much less prone to cause problems.
