As a noob starting out, I would like to learn how to create my own mixes. I am in civil engineering as a profession, but noticed that the countertop mixes are a bit different to normal heavy structure concrete - it is a bit more refined and specific, not as robust.
I figured the ingredients are at least the following:
- Silica sand (or best available sand)
- Cement
- Water
- Plastisizer add-mixture
- Metakaolin add-mixture (for efflorescence and alkali-silica reaction)
- Anti-shrinkage add-mixture
Am I missing anything here? Please feel free to correct me where needed. What do you guys use, or is it all hush-hush family secrets?
PS: I am situated in Africa, so I should not be competition to anybody over there :)
