Concrete AdmixturesWhat Are Admixtures For Concrete?

Water Reducing Admixtures(Also called plasticizer and super plasticizer) Plasticizers reduce the amount of water needed in the concrete mix. The less water (lower water/cement ratio) used to achieve a workable mix will result in a higher strength concrete. There are low, mid, and high range water reducers available that will lower the amount of water needed by 5%30%.
