Performance Data
Melflux SELECT 5731 F in combination with tartaric acid provides adjustable workability with excellent slump retention. The formulation concept with Melflux SELECT 5731 F is robust in terms of different CSA types. The strong reaction of CSA with Portland cement leads to a very high early strength. The final strength is comparable to ternary binder formulations based on high amount of HAC.
