Concrete plasticizers

گالن 20 - 220 - 1000 لیتری

The mechanism of action of this concrete superplasticizer, similar to PC100N, is based on generating negative charges on cement particles, which creates electrostatic repulsion between them. This repulsion causes the particles to separate, resulting in a more uniform distribution, reduced water demand, and improved workability and strength of the concrete. Additionally, the long-chain polymers present in the superplasticizer form a lubricating layer around the particles, facilitating their movement and enhancing flow.

Mechanism of Action of PR30 Concrete Superplasticizer The PR30 superplasticizer works by inducing negative charges on cement particles, creating electrostatic repulsion that separates them. This dispersion leads to a more uniform mix, reduced water demand, and improved workability and strength. Additionally, the long-chain polymers in PR30 form a lubricating layer around the particles, facilitating their movement and enhancing flow.

Dosage of PR30 Concrete Superplasticizer The exact dosage depends on factors such as ambient temperature, concrete type, mix design, and initial slump. Typically, the recommended dosage ranges from 0.2% to 0.7% of the cement weight.

Properties and Effects of PR30 Key benefits of PR30 include:

Increased slump
Up to 35% reduction in water-to-cement ratio
Enhanced workability and flow
Improved durability and long-term performance
Helps release trapped air in fresh concrete and mortar
Compatible with Portland and SRC cements
Facilitates placement of mass concrete
Significantly reduces bleeding
Lowers permeability and water absorption

Applications of PR30 Thanks to its unique features, PR30 is widely used in:

High-density and specialized concrete structures
Complex pours with dense reinforcement
Precast concrete production
Large-scale infrastructure projects (bridges, dams, towers, tunnels)
Self-compacting concrete (SCC)

Safety Guidelines for PR30 To ensure safe handling:

Always wear safety goggles and gloves
Rinse thoroughly with water if contact occurs with skin or eyes
Prevent freezing; store in a suitable location
Keep in a dry environment at +5°C to +35°C
Follow manufacturer instructions on the packaging
Use in well-ventilated areas; wear a mask if ventilation is poor

Physical and Chemical Properties of PR30 Concrete Superplasticizer

This popular product from Zarlochem is characterized by the following specifications:

Physical State: Liquid
Color: Light yellow
Chemical Base: Polycarboxylate ether
pH: Between 6 and 8
Density: 1.05 ± 0.02 g/cm³
Chloride Ion Content: Chloride-free
Solubility: Fully soluble in water

These properties make PR30 a reliable and efficient choice for enhancing concrete performance, especially in mixes requiring high fluidity and durability.

Method of Application for PR30 Concrete Superplasticizer

PR30 is applied as follows:

The calculated amount of superplasticizer, based on the concrete mix design, should be diluted with twice its volume of mixing water.
The diluted additive should be gradually added to the concrete during mixing.
It can also be added to ready-mixed concrete, followed by thorough mixing for 2 to 3 minutes before pouring.
PR30 may be introduced during concrete production at the batching plant or directly into the truck mixer.

Important Note:
Do not pour the carboxylate-based superplasticizer directly onto dry concrete materials, as this may cause clumping and negatively affect concrete performance.
