Fritz-Pak Concrete Superplasticizer, 1.2lbs. Cement Additive Improves Workability & Strength. Plasticizer Gives 25% Water Reduction or 6 Slump Increase. Great for Stamped Countertops, Patios & Floors

Works as described, excellent customer service. I would buy it again indeed. I had to fill in cells with rebar in a new house addition. I was looking for something to make the concrete more liquid without adding too much water. The product arrive in time and it was well packaged, no spills or damages. In the video is shown that it was mixed with a drill, but I needed a bigger quality and mixed it with a concrete mixer. It did not work and I contacted CS. From there I received an email with very thorough answers of all the questions I asked. I was advised to first mix the powder with some additive/liquid and then with the concrete. I mixed it with water and let it sit for at least 24h. When I tried again it worked like a charm. I could not fill the cells the way I expected because of the technik I used, but that has nothing to do with the product. If you need it for a small slab/counter top/some molds I think it will do the magic. It makes the concrete more liquid but in a some kind of pliable way. Looks like there is an oil in the mix and becomes more flowable, elastic.

cant get the ratio just right, also the bag spilled in the box

I used this product in conjunction with an FRC (fiberglass reinforced concrete) mix to produce a workable, thin, extremely strong plasticized concrete mix to apply over metal mesh on the reverse side of this 40" x 24" log-slice project. The slice is paua shell inlaid, so it was crucial to have a slurry that would "stick". The layer of concrete enhanced with this plasticizer varies from 2.5" to 1/8" thick, and cured very hard and strong across the entire back surface of the piece. Filled only 2 minor "cracks" with acrylic. Will use it again!

Certainly did its job as a plasticizer without issue. I was using it for standard gray concrete countertops, and even though we fix each batch thoroughly, there were little brown cherry pits pieces that we could not get to mix--and then they turned little areas of the concrete brown. It remains to be seen if these brown color bombs will show up after I strip the molds. I'm preparing for suckiness. If you, too, are trying to find a plasticizer for concrete countertops, I would strongly suggest you use a liquid one.

First, I recieved this product today and havent used it yet, so it is 5 stars for now, tomorrow I will use it and update this.Why 5 stars? Because according to other reviews, there are no "instructions", however I found a "how to use" and a "recommended dosage rate" card in the bag. See photos.***update*** 8-12-18So do to weather I was not able to use the super plasticizer until yesterday, but here is the update.I used this product to reduce the amount of water needed to produce a workable concrete which it did very well. I used the product at double it's intended dosage which reduces water requirements by about 1/3 to 1/2. In my mix I was also adding glass fiber and acrylic fortifier an am currently happy with the results now that I have removed the forms.

First problem, the bag burst inside the Amazon box, so before even opening the box, it was leaking out of the seams. Complete mess. Product comes in a plain, unmarked bag and I don't believe what I received was actually superplasticizer. I tried to use this for a concrete countertop. My first mix I tried to use the superplasticizer as a 25% water reducer and used 1 ounce per 80lb bag. Concrete was super stiff after mixing and I ended up putting in the rest of the recommended water and achieved a normal concrete consistency. Superplasticizer seemed to have no effect. For my second mix I doubled the amount of superplasticizer and premixed it with the full amount of water. This batch was even stiffer than the first with absolutely no slump. For my third mix I didn't use any "superplasticizer" and it was my highest slump mix of the day. For all I know, I got a bag of sand because it sure didn't work as a superplasticizer.

Only order this by itself, because otherwise its shoddy packaging will leak it onto other stuff in the same shipping box. I learned this the hard way. The powder had a strange, unpleasant smell, which doesn't matter for concrete, but does matter when it leaked onto other products in the same box, and I had to use soap to fully get rid of the smell.

To clarify. You will receive just one of the inner "soluble" bags. The soluble bag comes inside two clear plastic bags. None of the plastic bags has any writing on them (like the outer bag pictured in the Amazon listing). However, there was an instruction card inside one of the bags that recommended a rate of 1.75 pounds Supercizer 5 per cubic yard (cubic meter) - which is confusing as to why they listed "cubic meter" in parentheses next to "cubic yard" because there are 1.3 cubic yards in a cubic meter. My entire package weighed 1.4 pounds with all three bags - so probably about 1.2 pounds of material inside. So... If my math is correct and we assume an application rate of 1.75 pounds per cubic yard (not cubic meter) then I get about 1 ounce (weight - not volume) per cubic foot of concrete. Since there are 27 cubic feet per cubic yard and there are 28 ounces in 1.75 pounds of Supercizer 5. That's pretty close to one ounce per cubic foot. 1.037 ounces to be exact.... So, this bag with 1.2 pounds of material = 16 + 3.2 ounces = 19.2 ounces This bag will do about 19 cubic feet of concrete - PLEASE check my math...
