I don't know about white but you sure can lighten it a lot. You can also go to any colors like green,red,brown,and so on. A local brick yard is a good place to go to and find colors you can add to the mix.

can't get white when using grey portland,,, apron stores carry coloring powders OR, alternatively, 1 can buy universal tints from sher-wms for a small cost,,, add the color to the mix water then to the dry bagg'd mix,,, whatever color you use, remember it lightens when dry compared to the color you see when wet.

IF you need white, you'll have to use white cement.

Hello Mtowner, have you considered slab jacking the sunken piece of concrete. The process involves a hole being drilled into the sunken slab, then a limestone type grout is pumped into the cavity beneath the slab, and slowly the slab will raise up to the original height. You can check your local yellow pages for companies that do this and get several bids, it will cost you far less than replacing the slab, and it wont stand out as a new slab. Let me know what decide to go with.

If he's going that route, you don't think just prying up the low corner and washing sand under the slab is worth a shot?

There is some good info in this thread that I will find handy when I do a similar task soon... I just wish I could get replies like this to questions in my threads.

You do not "dye" concrete lighter.

The color of the concrete is manly determined by the sand color and the color of the cement (raw materials).
