Sustainable Workability Admixture for Concrete and Shotcrete
  • Improves workability
  • Improves ease of finishing
  • Ideal for congested reinforcement

Ever been frustrated by stodgy mixes or congested reinforcing? CONQOR B25 workability admixture is for you.

CONQOR B25 is a colloidal silica based admixture that is used to enhance the stability and workability of fresh concrete mixes. When mixed in concrete it produces a rheology modifying hydrogel within the matrix of the fresh concrete that enhances the plastic properties of concrete such as stability, cohesion and workability.

CONQOR B25 is designed to be used in ready-mix concrete or shotcrete, to be utilised in any below or above ground, exposed, or submerged concrete structure.

• Lubricating coarse ‘boney’ concrete mixes
• Stabilising high slump and self-compacting concrete mixes
• Pump aid
• Sprayed concrete/shotcrete
• Reducing formwork pressure enabling higher pour heights

How it works.

CONQOR B25 has been formulated for use in many types of concrete. It is compatible with most SCMs and most other admixtures.

No negative effect, on strength, drying shrinkage or permeability at equivalent W/C ratios.

It produces mixes that are thixotropic in nature that have a higher viscosity when static but become less viscous and mobile when pumped, vibrated or screeded. Slump or spread test results can therefore sometimes be lower for the same water demand, however, mixes are generally still workable at lower slumps/spreads. Using or increasing the dosage of a MRWR/HRWR, rather than increasing the water dosage to achieve the same slump/spread, is recommended.

If there has been slump/spread loss, adding a small dosage of HRWR to the mix on-site to restore the slump/spread is recommended.

Pre-project trials are recommended to assess the suitability and dosage of the admixture for your project requirements.
