Abstract

The paper studies the influence of composition and technological factors on rheological indicators of concrete mixes modified by various chemical additives. The rheological and water-reducing efficiency of super- and hyper-plasticizers in cement suspensions depending on their addition procedure was studied. The efficiency of a two-stage concrete mixing with the introduction of a plasticizer at the second stage with remaining 1/3 content of mixing water, which improves the efficiency of the additive by almost 20% in comparison with the traditional technology, was experimentally proved.
