Chemical Admixtures - Cement
Superplasticizers, also known as plasticizers or high-range water reducers (HRWR), reduce water content by 12 to 30 percent and can be added to concrete with a low-to-normal slump and water-cement ratio to make high-slump flowing concrete.

Use of Water Reducers, Retarders, and Superplasticizer
The use of WRA is defined as Type A in ASTM C 494. WRA affects mainly the fresh properties of concrete by reducing the amount of water used by 5% to 12% while maintaining a certain level of consistency, measured by the slump as prescribed in ASTM C 143-90. The use of WRA may accelerate or retard the initial setting time of concrete.
Cement saturation and the effect on stability and compressive
cement ratio is above 0.57, compressive strength of recycled aggregate concrete decreases as water – cement ratio increases which is similar to that of natural concrete (7). The adjustment of the water – cement ratio and super-plasticizer dosage was found to be one of the main properties in proportioning
- Do Plasticizers improve the strength of concrete?
- The use of plasticizers generally improves the physical and structural properties of concrete, as well as increasing the profitability of the project; We have learned from experiences that the results have been positive with respect to the compressive strength of concrete.
- What makes a good plasticizer?
- A good plasticizer makes concrete or mortar flow in a way that is different from how an air-entraining agent does it. But some plasticizers also add air to the material, making it easier to work. A good plasticizer should add 1% to 2% of the air to concrete at most because adding air to concrete makes it less strong.
- Which plasticizer is best for concrete?
- Polycarboxylate ether (PCE) – PCEs are high range water reducers that provide increased early and late strength. They allow low water-cement ratios. Sulfonated vinyl copolymers – These versatile plasticizers work well across different types of concrete mixes and temperature conditions.
- What is a plasticizer in concrete?
- and more resistant to cold. A plasticizer is an additive used in concrete to improve its workability, performance, and durability. Plasticizers are typically added to concrete mixes to make pouring, shaping, and finishing easier. They can also help to increase the strength and reduce the permeability of the hardened concrete.
- What is a hydrophilic plasticizer?
- The primary purpose of hydrophilic plasticizers is to improve the concrete’s plastic and flow properties, as evidenced by their increased wet ability. This plasticizer makes a lot of air get into the concrete mix. It is possible to lower the tension of the water in the solution and make the concrete more flexible.
- What is a plasticizer used for?
- Plasticizers are commonly used with polyvinyl chloride (PVC) and concretes. Plasticizers serve several crucial purposes in civil engineering materials: Workability – Plasticizers allow concrete to flow more easily into molds and around rebar during pouring. They make the concrete more malleable and improve slump. This makes large pours easier.
