RB-PC375 WATER REDUCING AND ACCELERATING SUPERPLASTICISER BASED ON POLYCARBOXYLATE

Description :

RB-PC375 has been primarily developed for applications in the ready mixed and precast concrete industries where the highest durability and performance is required. RB-PC375 is complies with ASTM C494 Types E and F and ISIRI 2930.

Usage :

  • The excellent dispersion properties of RB-PC375 make it the ideal admixture for precast and ready mixed concrete where low water cement ratios are required

Features and benefits :

  • high workability without segregation or bleeding
  • less vibration required
  • can be placed and compacted in congested reinforcement
  • reduced labour requirement
  • improved surface finish
  • increased early and ultimate compressive strengths
  • increased flexural strength
  • improved adhesion to reinforcing and stressing steel
  • better resistance to carbonation
  • lower permeability
  • better resistance to aggressive atmospheric conditions
  • reduced shrinkage and creep
  • increased durability

How to use :

RB-PC375 is a ready to use admixture that is added to the concrete at the time of batching.
The maximum effect is achieved when the RB-PC375 is added after the addition of 50 to 70 % of the water. RB-PC375 must not be added to the dry materials.
Thorough mixing is essential and a minimum mixing cycle, after the addition of the RB-PC375, 60 seconds for forced action mixers is recommended.
