RB-PC386 HIGH PERFORMANCE AND SLUMP RETENTION SUPERPLASTICISER BASED ON POLYCARBOXYLATE AND RETARDER FOR CONCRETE

Description :

RB-PC386 has been primarily developed for applications in the ready mixed and precast concrete industries where the highest durability and performance is required. RB-PC 386 complies with ASTM C494 Types B, D and G and ISIRI 2930. RB-PC386 is compatible with all Portland cements that meet recognized international standards. RB-PC386 is an ideal admixture in tropical regions.

Usage :

  • The excellent dispersion properties of RB-PC386 make it the ideal admixture for precast and ready mixed concrete where low water cement ratios are required.
  • This property allows the production of high ultimate strength concrete with minimal voids and therefore optimum density.
  • Due to the strength development characteristics the elimination or reduction of steam curing in precast works may be considered as an economical option.

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-PC386 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-PC386 is added after the addition of 50 to 70 % of the water. RB-PC386 must not be added to the dry materials.
Thorough mixing is essential and a minimum mixing cycle, after the addition of the RB-PC386, 60 seconds for forced action mixers is recommended
