Blended cement pastes made of Portland cement and fine sand (known in Egypt as El-Karnak cement) were made using a water-cement ratio of 0.25 by weight. Three pastes containing admixture (water-soluble condensates) were also prepared using a water-cement ratio of 0.25 and condensate (superplasticize
The following paper presents the results of the research carried out to investigate the influence of alkalis built in clinker phases and introduced from the outside together with make-up water, on the rheological properties of pastes in Portland cement at an early stage of hydration (less than 1 hou
