RHEOLOGICAL PROPERTIES OF CEMENT PASTES - EFFECT OF ADDITIVES

The effects of plasticizers on cement paste are as follows: (1) experimental results indicate the existence of a critical shear rate; (2) by using a particular vibration mixing method, reversible flow curves can be produced after mixing times which increase with decrease in w/c ratio of the paste; (3) at lower shear rates, the results indicate that a cement paste behaves as an elastic solid and bleeding occurs; (4) under the influence of a polymer additive, the paste assumes the qualitative rheological properties of the additive; (5) for the range of shear rates considered. The apparent effect of the additive is to decrease the workability of the paste. (TRRL)
