Use of Water Reducers, Retarders, and Superplasticizer
Water reducers, retarders, and superplasticizers are admixtures for concrete, which are added in order to reduce the water content in a mixture or to slow the setting rate of the concrete while retaining the flowing properties of a concrete mixture.
Master Builders Solutions concrete admixtures – enabling ...
Fairfaced concrete is as popular as ever and remains in high demand for interior finishing and facade design. Visually attractive surfaces require superior concrete quality. This is where Master Builders Solutions concrete admixtures come in: They ensure void-free, smooth and sharp-edged concrete surfaces that meet the highest requirements on esthetics and design and, at the same time
Chemical Admixtures - Cement
Retarding admixtures, which slow the setting rate of concrete, are used to counteract the accelerating effect of hot weather on concrete setting. High temperatures often cause an increased rate of hardening which makes placing and finishing difficult. Retarders keep concrete workable during placement and delay the initial set of concrete.
Seven Must-Use Concrete Admixtures (Additives) - The Spruce
Concrete Admixtures: Superplasticizers The main purpose of using superplasticizers is to produce flowing concrete with a high slump in the range of seven to nine inches to be used in heavily reinforced structures and in placements where adequate consolidation by vibration cannot be readily achieved.

- What are concrete additives?
- Concrete additives thatincrease the docility and workability of the mixture. This makes it possible to use concrete masses that would otherwise be impossible to place on site, or reduce the kneading water of concrete or concrete for the benefit of its strength.
- Is conplast rp264 compatible with other Fosroc Euco admixtures?
- Conplast RP264 is compatible with other Fosroc Euco admixtures used in the same concrete mix. If more than one admixture is used, they should be added to the concrete separately and not mixed together prior to being added. The resulting properties of concrete containing more than one admixture must be checked by prior testing.
- What is special defoamer for polycarboxylate concrete?
- Special defoamer for polycarboxylate Concrete is in a liquid form. Gypsum Retarder aims to slow down the gypsum setting time which in a low addition rate and good set retarding effect. It can be widely applied in Plaster Gypsum. Glue Gypsum, Prefabricated Gypsum components, Gypsum Stuffing, Gypsum Model Broad and Gypsum Decoration Coating, etc.
- Why do you need a concrete additive?
- In addition, the additive retards the initial hydration of the cement, resulting in a delay of the setting time. However, once the concrete has passed the initial setting, the hardening process continues normally. Uses To improve the effectiveness of water in a concrete mix.
- How much conplast rp264 can be used for retarder delay?
- The usual dosage is between 0.25 and 0.6 litres of Conplast RP264 per 100 kg of cementitious material, including fly ash, slag and microsilica. Properties The following results were obtained at a temperature of 20°C: Water soluble chloride content (CI-): ≤ 0,10%. Alkali content (Na2O equivalent): max. 5 mass %. Application method: Retarder Delay
- What is SR shrinkage-reducing admixture?
- SR shrinkage-reducing admixture was developed specifically to reduce drying shrinkage of concrete and mortar, and the potential for subsequent cracking. SR admixture functions by reducing capillary tension of pore water, a primary cause of drying shrinkage.
