Superplasticized flowing concrete: durability properties
Magazine of Concrete Research, 1984Synopsis This second paper reporting the investigation undertaken into the properties of superplasticized highworkability concrete describes the freezing-and-thawing and wetting-and-drying durability of strictly flowing concrete. It is shown that flowing concrete with a cement content equal to or greater than the minimum specified for a structural ...

Fatigue Behavior of Superplasticized Concrete
Cement, Concrete, and Aggregates, 1985Abstract Although many studies have been conducted on the physical properties of superplasticized concrete, very little research has been reported on the fatigue properties of superplasticized concrete. The purpose of this study was to determine the fatigue properties of concretes with superplasticizers and compare these properties with ...

Workability of superplasticized microsilica-portland cement concretes
Cement and Concrete Research, 1988Abstract The effect of the addition time of superplasticizers on the workability of concretes containing 0 or 10% microsilica was studied at different polymer dosages, water/cement ratios and mixing times. Cement pastes were also prepared and examined for workability, zeta potential and polymer adsorption.

Construction and Building Materials, 2008
Abstract Two kinds of aminosulfonate–phenol–formaldehyde condensate superplasticizers AS based on sodium p -aminobenzenesulfonate and SDMAS based on sodium p - N , N -dimethylaminobenzenesulfonate were synthesized. The properties of cementitious materials superplasticized with the synthesized superplasticizers such as the hydration heat and ...

Superplasticizer Adsorption on Synthetic Ettringite
SP-217: Seventh CANMET/ACI International Conference on Superplasticizers and Other Chemical Admixtures in Concrete, 2003Superplasticizers typically work within the first 2 hours of cement hydration. Therefore, early hydration products have to be studied to investigate their mode of action. The experiments in this paper demonstrate that ettringite is a preferred phase for the adsorption of polycondensate or polycarboxylate based superplasticizers, whereas polycondensate ...

Improved Superplasticized Precast Concrete Tiles
SP-173: Fifth CANMET/ACI International Conference on Superplasticizers and Other Chemical Admixtures in Concrete, 1997Concrete tiles were produced according to a new technology based on a vacuum treatment combined with a vibro-compacting placement of superplasticized mixture. Three concrete mixtures (all vibro-compacted according to this technique) were manufactured with different water-cement ratio (0.50 or 0.32) and in the absence or in the presence of the vacuum ...
