Has anyone ever attempted to use pea stone crushed granite with concrete to make a faux granite step or walkway?
I am in the process of making some samples for practice and so far I am running into a few issues.
1. The portland cement is grey not white or light grey so the cement voids around the crushed granite makes it all look to dark and unnatural. Adding some Tera Cotta integral color helps a little to remove the grey but its still dark.
2. Need a very high granite to cement ratio. Not sure what this will do for durability.
3. I need to grind the cream of the surface to expose the granite. This is very time consuming. I have tried rinsing the cream just before its cured but this does not create the effect I am looking for and causes some granite to be loose.
4. After adding calcium to the portland it still takes so damn long to cure!
I add calcium to the water before putting it in the cement since its not a powder, its small flakes, does this reduce its effect on the portland? I never have to use portland alone so this is a semi new area. The only time I use portland cement is for Fiber Reinforced Concrete which is different. I use Acryl60 at that point and it cures much faster but acryl60 is expensive.
