Oops, I am just wondering what stone material we should take for the wall!

Let´s have a look together at what there is. The following pictures give you an overview. 

If you want to know more, please look at the two most important artificial stone types in the information box:

Lime stones

Ceramic bricks

Here you see a few artificial stones, for example:

• Ceramic bricks (Link)

• Lime stones (Link)

• Concrete stones (Link)

• Lightweight concrete stones (Link)

• Autoclaved aerated stones (Link)

Please note: the following designations and dimensions of the stones are based on German standards. In other European countries other designations and dimensions can be standardized. Please contact your teacher or instructor.

We also need to know which mortar is to use.

By the way, do you know what raw materials are used for producing mortars?

Please try to answer the question spontaneously.
