Superplasticizer is a kind of powder form polycarboxylate ether superplasticizer manufactured through optimizations of molecular configuration and synthesis process.
It is suitable for cementitious mortars or concrete with requirements of high fluidity and high strength.
It can impart mortar high liquifying effect, easiness of defoaming and, long time retaining of those properties.
It is of excellent compatibility with various kind of cement binder and other additives, such as defoaming agent, retarder, expansive agent, accelerator etc.

Polycarboxylate ether (PCE) is indeed commonly used as a water-reducing agent in the production of dry mix mortar and concrete. PCE is a type of superplasticizer, a chemical additive that is added to concrete and mortar mixes to improve their workability and performance. Here's how PCE water-reducing agents are used in these construction materials:
1. Water Reduction: PCE superplasticizers are highly effective in reducing the water content in concrete and mortar mixes without compromising the mix's workability. This property is particularly beneficial because it allows for the production of high-strength concrete or mortar with lower water-to-cement ratios. A lower water content typically results in improved durability and reduced shrinkage.
2. Improved Workability: While reducing the water content, PCE superplasticizers can significantly improve the workability and flowability of the mix. This makes it easier to place and finish the concrete or mortar, especially in applications like pumped concrete or self-consolidating concrete (SCC).
3. Higher Early Strength: PCE superplasticizers can also accelerate the setting and early strength development of concrete or mortar, which is advantageous in construction projects where early demolding or opening to traffic is required.
4. Enhanced Cohesion: PCE-based superplasticizers help improve the cohesion of the mix, reducing the risk of segregation and bleeding. This is especially important in high-performance concrete and mortar applications.
5. Compatibility: PCE superplasticizers are typically highly compatible with a wide range of cement types and admixtures, providing versatility in construction material formulations.
The use of ONLY® chemical PCE water-reducing agents in dry mix mortar and concrete has become increasingly popular due to their effectiveness in optimizing mix performance and facilitating the production of high-quality, durable construction materials. The dosage of PCE in concrete or mortar mixes can vary depending on factors such as mix design, desired properties, and local standards. It is essential to follow manufacturer recommendations and industry guidelines when incorporating PCE superplasticizers into construction materials to ensure the desired results are achieved.
