Concrete/Cement Admixture-aliphatic Series Water Reducing Agent

Use of Water Reducers, Retarders, and Superplasticizer

Use of Water Reducers, Retarders, and Superplasticizers. Introduction. Many important characteristics of concrete are influenced by the ratio (by weight) of water to cementitious materials (w/cm) used in the mixture. By reducing the amount of water, the cement paste will have higher density, which results in higher paste quality.

Water Reducers, Mid-Range - North America

Water Reducers, Mid-Range Provide excellent concrete workability and finishability. Mid-range water-reducing admixtures promote superior workability and finishing of concrete, and improve concrete performance with excellent early strength and rheology. Non-chloride admixtures; Facilitates finishing to achieve desired surface appearance

Materials Selection Guide: Water-Reducing Admixtures ...

Dec 05, 2006 · Decreasing the water content reduces the water-cement ratio, thereby increasing the resulting concrete's strength. These admixtures can be broken into three main categories. Conventional water-reducing admixtures—also known as low-range water reducers—represent the first generation of water-reducing admixtures that have been around for more ...

Revealing the Mystery of Admixtures: Water-Reducing and Set ...

May 29, 2010 · Water-Reducing Admixtures Water reducers do essentially that: reduce the amount of mixing water required to obtain a given slump. This can result in a reduction of the water-cementitious ratio (w/c ratio), which leads to increased strengths and more durable concrete.

Superplasticizer I Concrete admixtures I Super plasticizer

By reducing the amount of water. The cement paste will have higher density, which result in higher paste quality. An increase in paste quality will yield higher compressive and flexural strength, lower permeability, increase resistance to weathering, improve the bond of concrete and reinforcement, reduce the volume change from drying and ...

Effects of Shrinkage Reducing Agent and Expansive Admixture ...

This paper investigated the influences of shrinkage reducing agent and expansive admixture on autogenous and drying shrinkage of ultrahigh performance concrete (UHPC) containing antifoaming admixture. The shrinkage reducing agent was used at dosage of 0.5%, 1%, and 2% and the expansive admixture was used at dosage of 2% to 4% by mass of cementitious material. The results show that the air content of UHPC increases with the higher addition of shrinkage reducing agent and expansive admixtures. How

Performance of Different Water Reducing Chemical Admixtures

The variables include cement types (ordinary portland cement, blended cement replaced by slag powder of 4080 and 7900 cm2/g), air-entraining (vinsol) chemical admixture, water-reducing (lignosulfonate type) chemical admixture, high-range water-reducing and air-entraining (naphthalene, melamine, polycarboxyl, and amion-sulfonate types) chemical ...

A Closer Look: Water-Reducing Admixtures - NPCA

Water-reducing admixtures have a similar backstory – researchers stumbled upon an admixture’s impact on water demand while trying to evenly disperse pigment in concrete. In 1930, Cabot Corporation had promised to create a black concrete for a local state road, but trial batches yielded a blotchy result.
