Whats are the most commontly used high performance concrete additives?

High-performance additives are also called HPC additives. Some commonly used concrete additives are superplasticizers, cement accelerators, fibers, defoamers, and cellulose ethers such as HPMC, MHEC/HEMC, and HEC.


Superplasticizers are high-efficiency water-reducing agents. It improves the workability and fluidity of the concrete without compromising its strength.


Cement accelerators are, for example, calcium formate. It’s used to expedite the setting procedure and promote the early strength of the concrete.


Fibers are used for concrete reinforcement. Our most popular fibers are Polypropylene fiber, PVA, PAN, and PET. You may consult us for further product-related questions.

How to evaluate concrete workability?

Concrete workability assesses the uniformity and ease of pouring and compaction during production. It is a comprehensive measure of flowability, cohesiveness, and water retention.


· Flowability. It refers to concrete flow and fills molds.

· Cohesiveness. It indicates the materials’ ability to stay mixed without separating or segregating.

· Water retention. Concrete exhibits its ability keep water content during production.


The ideal workability exhibits easy pouring, strong cohesion, and minimal water loss. Striking this balance ensures efficient and durable construction.

What concrete additives are considered sustainable concrete additives?

Sustainable concrete additives come from the earth’s natural renewal resources. For example, cotton or wood pulp. It includes cellulose ethers, water reducing agents, including PCE and SM water-reducing agents. They can result in more sustainable concrete with lower water usage.


By implementing sustainable concrete additives into construction operations. The building industry will eventually reduce its carbon footprint.

Do you have concrete additives for cold weather?

In cold weather conditions, concrete face particular challenges, such as delayed setting time, compromised strength, and freeze-thaw damage. To handle all the problems mentioned, some concrete additives are recommended in winter.


Accelerators and anti-freeze agents are typically used in such conditions. Accelerators promote early concrete strength by reducing its setting time. Anti-freeze agents are designed to lower the freezing point of concrete admixtures. It maintains good workability.

How much superplasticizer should be added to concrete?

The superplasticizer dosage in concrete varies depending on factors. For example, the type of superplasticizer used, the desired concrete properties, and the mix design.

The typical dosage of superplasticizers usually ranges from 0.1% to 0.3% by weight of cement content.
