Concrete Plasticizers, Cement & Plastic Fillers | USG
Cement & Plastic Fillers. Builders and project managers count on USG’s selection of concrete plasticizers and cement plasticizers to strengthen their structures. Our concrete plasticizer products reduce the water/cement ratio to achieve better results. View our plasticizer admixture for concrete and other offerings below.
STUDY OF CONCRETE WITH VARIOUS TYPES OF PLASTICIZERS AND
Practical value of common concrete water-cement ratio moves within 0.35 to 0.60 depending on type and effect of added plasticizers or superplasticizers and required consistency of fresh concrete. Low water-cement ratios that may get under 0.25 is use namely with new modern types of concrete like RPC
15 Types of Admixtures Used in Concrete - The Constructor
Normal plasticizer reduces the water demand up to 10%, mid-range plasticizers reduce the water demand up to 15% while super plasticizers reduce the water demand up to 30%. Calcium, sodium and ammonium lignosulphonates are commonly used plasticizers.

Silica fume is one of the most important pozzolanic additives which are used to improve durability of concrete. Silica fume is difficult to handle in bulk form in the concrete industry.Special procedures are needed for the metering and, in particular, to achieve adequate dispersal.In practice it is therefore normal to use the silica fume addition as an aqueous dispersion with a solids content
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.
- What are plasticizers & water reducers?
- Plasticizers and water reducers are chemical admixtures used to make concrete more workable. Unless the mixture is “starved” of water, increasing the w/c ratio reduces the concrete’s strength. An increase in durability is achieved by decreasing the water content (without “starving” the concrete).
- How do you mix plasticizers with pozzolanic ash?
- Plasticizers are frequently used in conjunction with pozzolanic ash while making concrete. This mix proportioning method is typically utilized when making high-strength or fiber-reinforced concrete. One to two percent by weight of plasticizer added to the cement is usually all that is needed.
- 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 are additives for concrete?
- Additives lower construction costs, alter the properties of hardened concrete and maintain the quality of concrete throughout mixing, transport, pouring, and processing. These substances are sold in ready-to-use form and applied to concrete either in the plant or on-site. Stay with us to discover more about additives for 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 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.
