PROTECRETE Mix Water Conditioner Product Information Sheet

What it does
PROTECRETE-MWC (Mix Water Conditioner) is a revolutionary product which has no equal in today's concrete marketplace. Unlike shrinkage reducing admixtures which are added to already-mixed cement, MWC is added to the mix water before any other components. MWC changes the chemical composition of the water in such a dramatic way that virtually all of the mix water is used (unlike ordinary concrete where a great deal of bleed water is left over). Because all of the mix water is used, there are no large voids left when the bleed water comes up, leaving the concrete as durable as any concrete produced today.

You'll immediately see the difference MWC makes to your concrete. MWC creates a very homogenous mix, meaning the ready-mix is consistent all the way through and doesn't separate. Unlike normal batches, the last of the load looks as good as the first.

Finishers like MWC, too. The workability is very good, and the concrete is easy to finish. You can save up to 25 percent of your normal finishing time.

Last but not least, MWC is made of only natural ingredients that are non-toxic and environmentally friendly. This makes MWC perfect for applications involving food service and where safe environments are needed for children or animals.

What it is
MWC is a clear, environmentally neutral, non toxic, odorless, non VOC or VOS liquid. Concrete containing MWC at the recommended dosage rate of 10 ounces per hundred weight has been shown to produce concrete with virtually no plastic shrinkage cracking and virtually no curling. As measured per ASTM C-157, it has a shrinkage rate of 0.015.

How to use
The recommended addition rate for normal batching is 10 fluid ounces per CWT (100 pounds) of cement. MWC is added directly to the mix water.

Where utilizing a mix water holding tank for variable cement content batching, pour or pump the predetermined volume of MWC into the mix water holding tank. Add total amount of mix water, then add balance of mix.

As an alternative, MWC can be poured into a clean, empty transit mixer truck just prior to putting under the batch plant for loading. With the mixer turning in its mixing mode, load approximately 90% of the total planned mix water volume, then begin loading cement, aggregates and the remainder of the mix water.

Adjusting the mix
MWC will enhance any mix design. For optimum benefits, additional water is highly recommended, in the same fashion as a silica fume mix design requires additional water. We recommend a correction of 1.06. With this adjustment, the slump will be approximately 3«-4 inches. If this correction is not made, the slump will be approximately 2-2« inches.

Finishing & set times
Longtime finishers have said they could even go back to their old wooden tools because (1) the concrete stays put, (2) there's no separation between aggregate and water, (3) there's no drag on the finishing tools, and (4) there's lots of cream to work with, meaning that workability and finishability are excellent.

MWC has a slight retarding effect on initial and final set times of about 8 percent. This is advantageous, as it gives finishers more cream for a longer period of time.

The final product
MWC helps you get to your ultimate compressive strengths more quickly. Independent testing has shown that MWC can increase compressive strength by as much as 26 percent at 28 days.

Packaging and availability
MWC is available from authorized distributors of Applied Concrete Technology, Inc. in 5-gallon pails and 55-gallon drums.

Compatibility
MWC is compatible with all admixtures.

Flammability
MWC is not combustible or flammable. It has no flash point.
