I cast some concrete floor tiles but I had paid several hundred dollars to go on a basic casting course in Joburg and then, as I got on with the teacher, went out for some beers with him and he agreed to provide an additional course answering my specific questions for several hundred more bucks.
Not only did the recipe include specific cement, specific grades of specific sands, water and various reinforcements, it also required four powder additives that are not easy to get hold of as well as a liquid additive.
Try buying Woolastonite in your local builders merchants! Won't tell you how much of it you need here though...
If you pay me $500 I might give you the recipe.
The slabs were great... not sure if the Woolastonite was necessary as that was for another recipe but when I finally got hold of it, I could only buy it by the tonne so had to get rid of it...
