There's a difference between cement (which can be as simple as a sand castle) and modern cement. Strength is the biggest factor; it's the difference between buildings lasting thousands of years and only a handful of seasons. Considering the huge temperature swings on Mars, we're looking for a very specific kind of building material so I imagine only specific soils will do. Volcanic ash (which, awesomely, is what made Ancient Roman concrete as good as modern concrete) is also hard to come by on Mars, calling it not very geologically active is an understatement. Even today we need specific kinds of sand to make the concrete for our foundations in disaster prone areas; in some ways it's amazing we can find worthwhile concrete at all. There's a reason most of our Mars building material plans today involve ice, it's much more readily available and gets stronger the colder it is... To a certain extent anyways.
That said, there are plans that do work with probably 'average' martian regolith: https://www.accessscience.com/content/sulfur-concrete-as-a-construction-material-on-mars/BR0208161
They just require a lot of sulfur first. And since sulfur is kinda yellow on Mars... Huh. You know, I think the devs have actually done something perfect here. You'd look for yellowy sand to gather up, heat to 110+ degrees C, then get really strong concrete out of it.
