PC-Conflow® EH serves as an admixture specifically designed for grouting ducts within post-tensioned or pre-stressed concrete structures using cementitious grout. This product guarantees lasting contact and a superior bond with the grouted
surfaces. Its expanding properties mitigate the settling of fines before the initial set, thereby decreasing grout shrinkage and ensuring optimal workability for a successful grouting process. Moreover, within three days post-grouting, it achieves high frost resistance, meeting the required standards for grouting pre-stressed structures.
