  • High Range Polycarboxylate Superplasticizer - China

    price: contact company for price

    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.

    Specifications

    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 /

    3d /

    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.

    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.
