15 Types of Admixtures Used in Concrete - The Constructor
Concrete admixtures are of different types and they are as follows: Water Reducing Admixtures Retarding Admixtures Accelerating Admixtures Air entraining concrete admixture Pozzolanic Admixtures Damp-proofing Admixtures Gas forming Admixtures Air detraining Admixtures Alkali Aggregate Expansion Inhibiting Admixtures Anti-washout Admixtures

MasterCast 900 | Master Builders Solutions - North America
MasterCast 900 plasticizing admixture, based on a unique, patented chemistry, improves the production efficiency and aesthetic appeal of manufactured concrete products. MasterCast 900 admixture exceeds the functionality of traditional plasticizing chemistries. It additionally disperses cement, pozzolans, and integral pigments, further reduces
Use of Water Reducers, Retarders, and Superplasticizer
Other benefit of using WRA is that higher concrete density is achieved which makes the concrete less permeable and have a higher durability. Retarding admixtures. The use of this admixture is defined in ASTM C494. There are two kinds of retarders, defined as Type B (Retarding Admixtures) and Type D (Water Reducing and Retarding Admixtures).
Concrete Admixtures (Additives)- Types, Selection, Properties
a) At a given w/c ratio, this admixture increases the workability, typically by raising the slump from 75 mm to 200 mm. b) The second use of this admixtures is in the production of concrete of normal workability but with an extreme high strength (super plasticizer can reduce the water content for a given workability by 25 – 35 percent

- What are the different types of concrete plasticizers & superplasticisers?
- CEMEX Admixtures concrete plasticisers and superplasticisers can be individually tailored to your needs. ISOFLOW Concrete plasticizer and superplasticizer based on polycarboxylate ethers (PCE). ISOFLEX Concrete plasticizers and superplasticizers based on conventional raw materials (sulfonates) and polycarboxylate ethers (PCE). ISOPLAST
- How do additives affect the flow behavior of concrete?
- The ideal interaction of additives and the raw materials used (cement, aggregate, water) influences the flow behavior, the water content, the consistency stability and the smoothing time of the concrete. CEMEX Admixtures concrete plasticisers and superplasticisers can be individually tailored to your needs. ISOFLOW
- What are chemical admixtures used for?
- Chemical admixtures that help speed up the hydration process and shorten set times. Typically used in colder environments. Water Reducing / Retarding chemical admixtures help slow down the hydration process and increase set times and slump life, while also providing water reduction and plasticizing benefits.
