Rated 5.0 out of 5.0 by GFactor Makes Rapid Set Products Flow
First off, this is only designed to work with Rapid Set Products. There are a ton of manufacturers and admixes in today's world, but this does not mean they will all play together well. So if you are mixing your own secret receipe of concrete, I would not use this, but if using a Rapid Set Product then 100% it works great.
The more water you add to a cement based product the weaker the final product becomes. So when you have an application that you need it to flow or need to be able to ensure it gets into ever nook and cranny or a mold, or into small gaps, instead of adding more water (which only weakens the mix), add one of these, or up to four packets for each 50lb bag of Cement All, or which ever Rapid Set product you are using.
If you have never used a product like this, it really is amazing how this little packet of white powder will suddenly turn your thick mix into a smooth, flow-able one. Just sprinkle it in, and continue to mix like normal. In a matter of seconds, your mix will transform. Very Cool!

Rated 3.0 out of 5.0 by GHDave Certainly boosts fluidity, but retards set
I ran out of my usual plasticizer (Riteks 7000 polycarboxylate) that I use for self-leveling microtopping so I picked this up. I works well enough and boosts fluidity but not as well as Riteks.
However as I write this it's been 24 hours and I've only got a very soft set - like jello and I'm very concerned. Usually by now I can stand on it, this time my foot sank in.
I used 4 bags mixed in with two 80lb bags of sackrete 3-1 sand mix + 6 quarts of portland cement + 2 gallons of 50/50 acrylic fortifier/water + 14 ounces of liquid latex + 4oz (by volume) fiberglass fibers. I added another ~gallon of water during the mix.
The flow control must contain a set retarder, or it reacted badly to the acrylic&latex admix.
I'll update after a day or so.

Rated 5.0 out of 5.0 by Wood2017 Makes Concrete Flooooooow
I used this product with Rapidset concrete for use in a semi-complex concrete mold. I had never worked with mixing concrete before and my first attempt did not turn out well (I think I had too much water). My second attempt turned out very good. This flow control powder helped the concrete flow into the mold cavities well and I had minimal bubbles/voids in my finished product.

If you need a smooth flush surface from Rapid Set concrete add this as per the directions and you can not go wrong!

Rated 5.0 out of 5.0 by Verified Reviewer I love this stuff
excellent product to achieve a smooth and pourable mixture that has less water which equates to higher strength. mix rapid set cement to thick milkshake consistency, then sprinkle in flow control to desired consistency. it's really cool to watch the thick cement mixture turn watery with just a little bit of powder.
