In this method, instead of glueing the paver to the concrete with mud, the paver is laid on top of a layer of sand. Many pavers can be set using this method with no problems. But some natural stones could develop issues if set using this installation method. Pavers were designed to be set in sand. So why could some develop issues if set in sand ...

How to Make Cement And Concrete From Scratch

When slacking lime you can use low water amounts and you will be left with a powder or more water and be left with putty. Either can be used as cement when making concrete. As CO2 in the atmosphere reacts with the cement in your concrete it reverts back to limestone. Basically turns back into stone.
