SikaRapid®-800 P is a hardening accelerator in powder form for cementitious dry mortar and concrete. SikaRapid®-800 P develops after a few hours very high strengths.
Good strength development even below 10°C
Adjustable workability time 10 – 50 min
Small gap between the beginning and end of the setting
Usage
SikaRapid®-800 P is especially suitable for any application where high early strength development plays a major role, or is of crucial importance within the first hours. SikaRapid®-800 P is used but is not limited for the following applications:
rapid setting fixing mortars and grouts for fast loading
precast elements for early demoulding and fast removal
fast setting foam mortar
fast setting tile adhesive
fast setting post fix dry mortar
Advantages
SikaRapid®-800 P provides the following advantages through accelerated hardening of mortar / concrete within 20 min to 2 hours depending on mix design, fresh mortar temperature and curing conditions:
workability time 10 – 15 min
end of hardening 15-18 min
aprrox. 25 MPa after 24 h at 20°C in concrete
good strength development even below 10°C
adjustable workability with retarder up to 1 hour
SikaRapid®-800 P does not contain chlorides, nitrates or any other ingredients which promote the corrosion of steel. It is therefore suitable for use in reinforced and prestressed concrete structures.
