Fluidizer 1 lb - Dry superplasticizer for Any Concrete Countertop Mix

Works great. I just sprinkled a small amount into the 5 gallon bucket after starting to mix the 80 lb bag of cement. Doesn’t take much to make a big difference. Mix it for a good minute at least. Two is better. Cement became much more flowable without adding any extra water.

I love this product. All it took was one or two tablespoons added to a bag of Rapid Set concrete which was mixed with the minimum amount of water/latex admixture to turn it from barely able to clump to the consistency of a thick pancake batter. This makes it easy to pour the mixture into 2 inch wide cracks in concrete slab as well as finishing the surface. Using minimum amount of liquid gives the highest strength concrete. This helps reduce cracking due to winter freeze and thaw . I filled about 35 feet of cracks in patio varying from 2” to 6” last fall. This spring the patio is solid without any cracks. Note the Rapid set concrete has a higher strength than typical bags of concrete made with Portland cement. The one downside is that the Rapid set concrete sets up within about 15-20 min even when using set control and working at 50F (late fall. Western NY). Great product.

I mixed up a few batches of really dry, stiff concrete, and just tested each one to see how little of this plasticizer I could add, and I was kind of amazed how much difference it made! There are other brands, but this one was inexpensive and did the job really well.

Perhaps I’m doing something wrong. The instructions are very unclear on how much to add. Then it takes awhile to start working. So most of the fluidity came when it was already in my mold. Then all the water extraction became an issue.

Quality additive

Works like magic to improve flow without thing the mix. I use this product to cast concrete garden bed sides at 1.5" with a bit of fiber added.

Works great if you follow the directions. I didn't get any separation, shrinking, and two weeks later no cracks. (1.5" counter top)

It had clumps in it and ruined my concrete countertops
