“We have been using Whitemud’s Metakaolin for seven years as a standard mix component in our ready mix concrete. ASR pop-outs was one of the primary reasons why we made the decision to batch all of our concrete with Whitemud’s Metakaolin. Since we started using MK, we have had zero reported instances of ASR pop-outs on our slab mixes. We have also come to appreciate the other positive attributes of MK including reduced shrinkage, improved workability and creaminess, and increased durability through a reduction in permeability. When crews first work with our MK mix, we frequently hear, “WOW! These guys really know how to make concrete!” MK in the mix produces a smoother product that rakes, floats and power trowels beautifully.”

“Using new products can sometimes be problematic however we had no issues integrating Whitemud’s Metakaolin into the project. The finishers found the mix to be really creamy and placing was no different to our normal mix. Coloration was more consistent on the form side of the slab. We would have no hesitation using this product on our next job.”

“The main challenges on the Bow Tower job were shrinkage and pump-ability. The flow-ability through the congested rebar required reducing the maximum aggregate size which increased the potential for shrinkage.  Metakaolin in the mix assisted in alleviating these issues. Our concrete mix design was able to satisfy the requirements for shrinkage and cracking. The pumping characteristics have met all requirements at the lower levels of the 58-floor structure. Metakaolin in our present mix designs has proven beneficial for LEED projects, early strengths, and stripping times.”

“I liked the Metakaolin concrete as soon as it came out of the truck. We were able to get our stripping strengths in 3 days, without accelerators. We can compress our construction schedule. Having Whitemud’s Metakaolin in the mix provides LEED points without adding work and time.
