CONQOR A80 | ADMIXTURE
Get reliable early strength from slag rich mixes.
Slag activator & strength accelerator for high-GGBS concrete & shotcrete. Helping ready-mix producers increase slag content without sacrificing early strength, concrete stability or construction schedules.
- Assist early strength
- Enhance stability
- Help meet low-carbon goals
CONQOR A80 | ADMIXTURE
Slag activator & strength accelerator for early strength in slag concrete & shotcrete.
The transition to lower-carbon concrete is creating new challenges. Increased SCM use can reduce early strength, slow construction schedules and introduce production variability. CONQOR A80 helps producers overcome these challenges while supporting sustainability objectives.
CONQOR A80 Strength Accelerator for high-slag concrete and shotcrete is a liquid admixture that is used to enhance the stability and early age strength development of fresh concrete mixes where GGBS (Ground Granulated Blast-Furnace Slag) content is 30 to 65%.
CONQOR A80 is compatible with all other MARKHAM additives and is formulated to overcome the effects of low temperatures on the early setting and hardening of GGBS concrete.

Who it helps.
Ideal Solution for
Concrete Mix Designers.
CONQOR A80 helps concrete mix designers maximise the use of GGBS (30-65%) and other supplementary cementitious materials by improving early-age strength development and concrete stability, particularly in low-carbon concrete mixes.
Also HELPS
Batching plants.
CONQOR A80 allows concrete producers to achieve the sustainability benefits of higher slag contents while maintaining practical construction schedules and earlier return-to-service requirements. CONQOR A80 helps ready-mix producers increase slag content without sacrificing early strength, concrete stability or construction schedules.
USED by
Structural engineers.
CONQOR A80 helps structural engineers achieve lower-carbon concrete designs without sacrificing construction practicality. By accelerating early strength development in GGBS concrete, particularly in cold weather, it supports faster construction schedules, earlier return-to-service, and greater confidence in specifying sustainable concrete mixes. Early strength confidence; reduced programme risk; stronger specification support.
works for
Shotcrete contractors.
CONQOR A80 promotes faster early strength development in sprayed concrete mixes, especially when GGBS is used.

Shotcrete
CONQOR A80 promotes faster early strength development in sprayed concrete mixes, especially when GGBS is used.
CONQOR A80 | ADMIXTURE
Cold weather construction
CONQOR A80 accelerates hydration and strength gain within the first 12-24 hours, even in cold conditions. Traditional calcium nitrate based accelerators do not work well below 8°C. CONQOR A80 is effective at 4°C.
CONQOR A80 | ADMIXTURE
HOW IT WORKS.
CONQOR A80 Strength Accelerator is a liquid admixture that has been formulated for use in concrete mixes where the addition of GGBS is required, particularly in colder weather.

Early hydration and strength
CONQOR A80 enhances early hydration and supports strength development within the first 12–24 hours, without significantly altering the setting or finishing times of the concrete.
CONQOR A80 | ADMIXTURE
Low temperatures
CONQOR A80 produces concrete mixes that will set and harden much more quickly, especially at low temperatures. Traditional calcium nitrate-based accelerators do not work well below 8°C. CONQOR A80 is effective at 4ºC.
CONQOR A80 | ADMIXTURE
Integrates readily
CONQOR A80 integrates easily into most mix designs without requiring adjustment to standard placing, finishing, or curing practices. Effective in slag mixes containing 30-65% GGBS.
CONQOR A80 | ADMIXTURE
Compatibility
CONQOR A80 is compatible with the majority of SCMs and other admixtures.
