Bricks on bricks

NASA states if you throw some polymer plastics in with the mars soil bricks, microwave them then we had a material we can use to make thick walls..

But what if it's easier than that?

Time to research more

We can make concrete on Mars, sulfer+ aggregate= concrete (bricks or more)  takes only a few hours to set whereas concrete on earth takes 24+ hours to set.. what does the plastic do and why microwave it?

I'll find out for us and make it better ;)

Frontier Construction Limited will be the name of my multiplanetary company !

Let the mind start bulldozing haha
