PC100N concrete superplasticizer is a high-performance additive based on long-chain polycarboxylate ether polymers, designed to optimize the effectiveness of water content in concrete mixes. Due to its unique properties, this product is ideal for producing high-strength and highly flowable concrete, ensuring maximum durability and performance. This liquid additive enhances concrete performance by significantly reducing water content in the mix, which leads to increased strength and reduced permeability against aggressive chemicals. Thanks to these features, PC100N is commonly used in specialty concretes such as self-leveling and self-compacting mixes, and in applications where a lower water-to-cement ratio is required. With this product, the water-to-cement ratio can be reduced by up to 40%, resulting in stronger and more durable concrete.

Mechanism of Action of the Best Concrete Superplasticizer PC100N The mechanism of action of the carboxylate-based concrete superplasticizer PC100N involves the addition of polycarboxylate ether to the concrete or cement mortar mix. These molecules form a charged layer around cement particles, causing them to disperse. The side chains of the polycarboxylate ether repel particles, while the hydrophobic force in the main chain attracts large molecules through the cement particles. This process relocates water molecules away from cement particles, resulting in a more fluid mix. Over time, the induced charges dissipate, leading to increased slump, improved workability, and enhanced cement hydration. To identify high-quality PC100N superplasticizer, check the product’s color. If it’s dark brown, it likely contains additives other than polycarboxylate ether and may lack the desired properties. Another method is to test the viscosity by touch—quality samples feel like oil, are uniform, and contain no sediment.

Dosage of the Best Concrete Superplasticizer PC100N The optimal dosage of PC100N is determined through multiple field tests, depending on factors such as ambient temperature, aggregate type and size, water-to-cement ratio, and other variables. Generally, the typical dosage ranges from 0.1% to 0.4% of the cement weight, though this may vary based on project-specific requirements.

Physical and Chemical Properties of the Best Concrete Superplasticizer PC100N

The physical and chemical characteristics of PC100N make it a powerful and effective concrete admixture. These properties include:

Form: Liquid
Color: Light honey
Specific Gravity: Approximately 1.18 g/cm³
Chloride Ion Content: None
pH: Around 7, nearly neutral

Its liquid form and light honey color, along with the absence of chloride ions and a neutral pH, make PC100N highly compatible with other concrete components and ideal for use in various concrete mixes.

Method of Application for Concrete Superplasticizer PC100N

There are several ways to use PC100N in concrete, depending on the manufacturer’s recommendations and the specific needs of each project. Common methods include:

Dilution with Water: The amount of superplasticizer is calculated based on the concrete mix design, then diluted with twice the volume of water used in the mix. This diluted solution is gradually added to the concrete during mixing.
Addition to Ready-Mix Concrete: PC100N can be added directly to ready-mixed concrete. After thorough mixing, the concrete can be poured. It is recommended to mix for at least one minute per cubic meter of concrete.
Addition at the Batching Plant or in the Truck Mixer: The additive can be introduced during concrete production, either at the batching plant or directly into the truck mixer.

Important Note: The carboxylate-based superplasticizer must not be poured directly onto dry cement. Doing so may cause clumping and negatively affect concrete performance.
