Plasticizers: Materials, Action and Uses Admixtures ...

The dispersing ability of plasticizers (water reducing admixtures) results in a greater surface area of cement exposed to hydration. For this reason there is an increase in early strength of concrete than that of admixture free concrete of the same water/cement ratio. Long term strength may also improve due to a more uniform distribution of the dispersed cement throughout the concrete. In ...

Superplasticizer - Wikipedia

Superplasticizers (SP's), also known as high range water reducers, are additives used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more. These additives are employed at the level of a few weight percent. Plasticizers and superplasticizers retard the curing of concrete.

Superplasticizer: Types, Advantages Disadvantages

Slump loss are greater than conventional concrete. 2. Addition cost for admixture. 3. They increase air – entrainment concrete. Uses of Superplasticizer: Superplasticizers disperses cement provides plastics with higher initial strength than free concrete with the same W/C ratio. Set retards are adductors that cause delays in the setting time of wet concrete mixes. Air entrances are added to ...

Plasticizer - Wikipedia

In the concrete technology, plasticizers and superplasticizers are also called high range water reducers. When added to concrete mixtures, they confer a number of properties including improve workabilityand strength. The strength of concrete is inversely proportional to the amount of water added, i.e., the water-cement (w/c) ratio. In order to produce stronger concrete, less water is added (without "starving" the mix), which makes the concrete mixture less workable and difficult to mix, necessitating the use of plasticizer

Cement Plasticizer Cement Concrete Plasticizers ...

Cement concrete plasticizers increases the workability of freshly mixed concrete without increasing the water cement ratio. Cement plasticizers are chemicals to be added in cement – concrete mixture. It is to be added in proportion of 0.1% to 0.4% by wt. of cement. It means in 50 Kg of cement bag, 250 gm to 400 gm of chemical has to be add. Addition of these doses reduces 5% to 15% of water ...

Use of Water Reducers, Retarders, and Superplasticizer

The extended-set admixture is widely used as a stabilizing agent for wash water concrete and fresh concrete. Addition of extended-set admixture enables the reuse of wash water to the next batch without affecting concrete properties. This admixture can also be used for long haul concrete delivery and to maintain slump. Factors affecting the use of this admixture include the dosage rate and the ...
