Well this is a crappy picture but here is a sample with the granite in the concrete. You really can't see the granite to well in this picture. I'll have to use our other camera when I find it. That top stone is sealed with an acrylic sealer. Really brings out the beauty of the concrete
I made another sample the size of a brick but I really loaded it with granite and very little cement, I also colored the cement terra cotta but after grinding it, after adding a lot more granite, it still doesn't look how I want. Basically the granite pieces are just spaced to far apart. If I want to do this I may have to find a way to get the granite closer together. Maybe finding a small crushed granite pea stone.
It takes very little money to do this so if I can perfect it this could be a cost efficient way of making granite steps without spending over $100 for one step. Instead I could make it for less than $20-30.
Doing this on an entire walkway would be time consuming and a lil more expensive I think because I would have to rent a machine to grind the surface of the walkway to expose the granite.
Winter is coming so I will put the sample outside to see how well it does through freeze and thaw cycles. Maybe with some salt in on area, Although this is not air entrained so even if it did flake it really won't tell me anything.
