Polycarboxylate Superplasticizer

PC-L
(Liquid, 50%)
 

Description
PC-L is a new generation of admixture based on polycarboxylate chemistry. PC-L is very effective in producing concretes with different levels of workability including applications that require the use of self-consolidating concrete (SCC). It meets ASTM C 494 requirements for Type A, water-reducing, and Type F, high-range water-reducing, admixtures.

Application
PC-L can be applied in hydraulic, electricity, port, bridge, railway, tunnel and highway projects.

Specifications
 

Features and Benefits
1. Excellent compatibility with various types of cements.
2. High water reducing rate, low dosage, and low slump loss.
3. Low chloride and alkali content, no corrosion to steel-bar.
4. High stability: no precipitation at low temperature.
5. Environmental friendly and nontoxic.

Dosages
PC-L  dosage normally ranges from 0.3% to 1.2% by weight of cementitious material. Recommended dosage: 0.4%.

Package
It is packed in 1000Liter per IBC Tank.

Use

1.     PC-L (50%) is always diluted to 10% to 20% concentration for use. For example, to make 1 ton of PC-L solution  (10%), please fully dilute 200kg of PC-L (50%) into 800kg of water.

2.     When making RMC-use admixture with PC-L, a certain amount of retarding agent and air-entraining agent need to be  added in the PC-L solution (10%). On special occasions when slump loss of concrete speeds up and segregation appears after casting, it's necessary to add MNC-BS. Here's the general formula to compound RMC-use admixture.

PC-L solution (10%):      980kg

Retarding Agent:              15-20kg

Air-entraining Agent:        2kg

The dosage of the RMC-use admixture is 2-2.5% by weight of cement.
