first diorama for TORNADO 1:32

First of all what is a Tornado? I assume its a modern fighter jet, possibly British?

This limits what can be done, most add a concrete base with maintenance vehicles & ordinance carts. What would be super cool is the aircraft undergoing a engine replacement in a hangar. I take you are past that point so even a simple concrete base with a pilot discussing repairs to a mechanic would suffice.

Now remember a diorama tells a story, without aid of text or assuming the viewer knows anything about the subject. Not a easy task to execute.

A vignette is a 'snapshot in time' Much easier to pull off without the criteria of a story line.

this is one is the tornado. but i would like to do this one! this scene. and i need help. what do i use for example and how..?

Fine sand paper makes realistic concrete.

Realize a diorama tells a story, what you are shooting for is a vignette or a 'snapshot in time'

so i use just  sandpaper..?

It can have a wash & dry brushed to bring out the texture. Look for a very fine grit in 'wet' some even come in light gray. Say 800+ grit.

Some pour plaster ect. to simulate concrete. Its a lot of fuss and still needs to ne sanded level to work. I figure the sand paper looks like scale concrete without all the fuss.

If its in sections (expansion joints) simply cut the paper in scale sections. This way you will have scale expansion joints.

The color is important as the texture, make sure you get the correct color. Add oil stains, painted lines & tire marks to relly pull off the illusion of scale concrete.

Have fun & post your results!

That would be considered neither diorama nor vignette in a show. It would be a model on a base. To replicate with grass in 1/32, you'll need to figure the width of the runway and size the base accordongy. That may be overwhelming for the aircraft, as well as where you're planning to display this. For a simple, single aircraft on display, you might want to forgo the dio idea and simply stain the base and add a unit patch or/or a data sheet on the aircraft. For tarmac, a thin layer of Celluclay or similar material smoothed out with a few expansion joints laid in then painted gray would suffice.
