BF 855 W is a high performance PCE-based superplasticizer for concrete with high early strength and excellent slump retention effect, without affecting initial setting time.
Fields of application:
– Self compacting concrete (SCC).
– Exposed concrete;
– High performance concrete (HL-Beton);
BF 855W is a high performance superplasticizer for achieving exceptionally extended workability times and allows high early strength developments in ready-mix concrete. improves the cement dispersion within the concrete significantly. This property allows the formation of a homogenous and low-viscosity cement paste which ensures an improved workability and facilitates the compaction of concrete.
