High Range Polycarboxylate Superplasticizer - Chinaprice: contact company for price
GD- PCR is a new generation of admixture based on polycarboxylate chemistry.
GD- PCR 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.
GD- PCR can be applied in hydraulic, electricity, port, bridge, railway,
tunnel and highway projects.
Solid content ( % ) 50±1
Water reducing rate ( % ) ≥ 25
Cl - Content ( % ) < 0.1
Na2SO4 content ( % ) <1.0
Slump Retention ( 60 min. ) ≥ 150mm
Slump variation( 1h) ≤ 60mm
Air content ( % ) ≤ 3.0
The time difference of setting ( min) Initial setting > +90
Final setting /
Ratio of compressive strength ( % ) 1d /
7d ≥ 140
28d ≥ 130
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.
GD- PCR dosage normally ranges from 0.3% to 1.2% by weight of cementitious
material. Recommended dosage: 0.4% .
200 L / Barrel, 1.1MT / IBC Tank, 20 MTs / 20’ FCL
T / T, L / C
within 10 workdays after receiving deposit or confirming L/ C
GD- PCR ( 50% ) is always diluted to 10% to 20% concentration for use. For
example, to make 1 ton of GD- PCR solution ( 10% ) , please fully dilute
200kg of GD- PCR ( 50% ) into 800kg of water.
When making RMC- use admixture with GD- PCR, a certain amount of retarding
agent and air- entraining agent need to be added in the GD- PCR 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.
GD- PCR 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.
