High Range Polycarboxylate Superplasticizer - China

Polycarboxylate superplasticizer 50%

Description

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.

Application

GD- PCR can be applied in hydraulic, electricity, port, bridge, railway,

tunnel and highway projects.

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.

Dosages

GD- PCR dosage normally ranges from 0.3% to 1.2% by weight of cementitious

material.

Recommended dosage: 0.4% .

Package

200 L / Barrel, 1.1MT / IBC Tank, 20 MTs / 20’ FCL

Payment terms

T / T, L / C

Delivery time

within 10 workdays after receiving deposit or confirming L/ C

Use

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.
