Alpha ProFluidizer 1 lb - Dry superplasticizer for Any Concrete Countertop Mix

Amazing new tech for concrete! Less water = greater strength. Those who complain of separation are using too much. The online instructions even explain this. First, figure out the amount of CEMENT (not aggregate) in your mix. This is the number that you multiply x .00375. For instance, a 60 lb bag of Sackrete high strength (4kpsi, 1:2:3 mix) would take 17grams as it's just 1/6th cement. That's just a starting point though. Dose will vary so experiment. Also, it can take several minutes of mixing to see the full result.

This "fluidizer" allows cement to be added to water and incorporates the two compounds more easily. Don't add additional water, just follow instructions. It's a powder that makes stirring more effective and faster. Regardless of your method whether by hand or drill paddle the blending of ingredients goes better; and you don't need much. About 2 Tbs. For a craft sized batch.

I got this for my new hobby, making paving stones and plaques from molds. Saw a lot of recommendations to use a superplasticizer, so you can use less water and get more strength. What I found is that, almost immediately, the water separates and floats to the top, and the cement and aggregates sink to the bottom and harden. This makes it impossible to use vibration to remove air bubbles from the surface of the piece. I can see it being good for countertops though, as the liquid on top will make a very smooth surface.

I used this for a concrete countertop pour and it worked great. It’s a gen3 recipe. A little goes a long way. Would recommend and will buy again.

A little goes a long way, makes plaster work much easier, though more experiments needed with color stability..

Great stuff. Number one complaint I see from others is that it causes segregation of the mix and water immediately comes to the top and the aggregate falls. If this is the case, you've used way too much of the plasticizer. It only takes a small amount and it is based on cement weight only so get a good scale. Consideration must also be given to plasticizers already in most pre-bagged mixes since even the smallest additions of plasticizers can cause aggregate segregation so starting with about 25% of the recommended minimum amount is a good idea. Another tip is slaking your mix momentarily after the initial mix. Let it sit for 3-5 minutes and remix for further dispersal of chemical additives. I've cast numerous baullisters, manufactured stone, decorative pieces and much more. Patience and test pours are the key to success. Also, when casting, keep an eye on your curing temps. If they start becoming excessive start chilling your water with ice down to 55 degrees. It will help extend the cure time and reduce heat stesses in your work. Remember it only takes a little.
