Water Reducing Plasticising Admixtures | CEMEX UK
Incorporating plasticisers into the concrete can be used to increase consistence without the need to add further water therefore not compromising specified strengths. Plasticisers can also be used as water reducers to reduce the quantity of mixing water required to meet a particular class of consistence.

Use of Water Reducers, Retarders, and …
WRA has been used primarily in hot weather concrete placing, pumping, and tremie. Careful concrete placement is required, as the initial setting time of concrete will take place an hour earlier. It is also shown that the use of WRA will give a higher initial concrete compressive strength (up to 28 days) by 10% compared to the control mixture. Other benefit of using WRA is that higher concrete density is …

Polyacrylamide in Cement Concrete Modification 2014-11-12 15:16:48 Polyacrylamide can be used to modify the cement concrete in order to improve its flexural strength, its bond strength and its flexural toughness, and its abrasion resistance has a significant effect, it can reduce the crushing ratio, the permeability and the contractility.
Chemical Admixtures - Portland Cement Association
Flowing concrete is a highly fluid but workable concrete that can be placed with little or no vibration or compaction. The effect of superplasticizers lasts only 30 to 60 minutes, depending on the brand and dosage rate, and is followed by a rapid loss in workability. As a result of the slump loss, superplasticizers are usually added to concrete at the jobsite. Corrosion-inhibiting admixtures ...
