Interaction of polyethylene glycol with cement hydration products and its effect on the properties of concrete

To determine the interactions of polyethylenglycol with mineral binders used model systems were prepared using slaked lime and fly ash. Studies were performed using X-ray diffraction and differential thermal methods. During the experiment, it was found that the introduction of PEG to the concrete mix in the early stages of the hardening process are slow hydration as in the later stages of solidification - binding observed in portlandite organo complexes.
