use white sand


Should white sand be mixed with white mortar to keep the mortar white?

Usually not unless white sand is all you have. White sand is normally beach sand which means it is round and relatively smooth, masonry sand is normally a sharp sand. For glass block they often do use white sand though.

Years ago we made white concrete for a grocery store, and we had to have white sand, rocks, and cement. I imagine your situation would be similar, any colored sand would overpower the whiteness.

When we supplied the concrete for McDonalds Hamburger university training center,white concrete was specified for some floors,and they used 3 inches of regular concrete dry tamp for the base and topped it with white cement mixed with silica sand.

I know why they do it, but wouldn't painting the floor white every couple years be cheaper than the $400 per yard we were charging?

The sand color doesn't have any effect on a properly mixed and finished slab. If it will be ground, obviously this does not apply.

It you want it white you need to use white sand. Don't believe me get different colored sands & make test batches. They will be close to the color of sand you are using. The color of the sand has nothing to do with it is acceptable to use in a particular mix. The ASTM # does C-33 for concrete mixes & C-140 something for mortar mixes.

If you have sand exposed on a concrete slab, then you either ground it or did not mix it properly. The paste will coat each particle of aggregate and thus the color of the sand does not matter for normally finished concrete.

For mortar ( ASTM C-144 is the proper standard, FYI) it depends upon how and when you tool it as to whether the sand will make a difference in the color. Normally, in mortar it does because the joints are tooled, exposing the sand.
