Retarder additive Rapid®-800 P

for mortarfor concrete

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.
