SIKA MICROCRETE 2000
Sika Microcrete-2000 - Dual shrinkage-compensated, flowing, cementitious repair material for formwork repairs
Sika Microcrete-2000 is a dual shrinkage-compensated pre-bagged flowing micro concrete. It has very good flow properties and has been specifically developed to reduce heat generation. As such, large volume repairs may be performed without addition of aggregates. With its high silica fume content and combination of blended cement, a highly dense, impervious and hence durable repair mortar is obtained.
Sika® Microcrete-2000 contains blended cement, silica fume, fibres, graded aggregates and additives which give rise to controlled expansion in both the plastic and hardened states.
Sika Microcrete-2000 is suitable for structural repairs to marine structures, bridges, columns, etc. It is also conducive for use in the following repair works where single placing is in excess of 25 mm thickness:
- Bridge columns and beams
- Jetty piles
- Concrete piling
- Grouting applications
Sika® Microcrete-2000 can be applied by gravity pour or mechanical pumping.
