Silplast R20
Silplast R20 is general purpose, non-shrink, cementitious micro concrete which is used for repairs to damaged reinforced concrete elements, particularly where access is restricted and where vibration of the placed material is difficult or impossible.
It is suitable for various structural strengthening measures such as encasement build-ups, jacketing, piletop encapsulation resin system, etc.
Silplast R20 is supplied as a ready to use blend of dry powders which requires only the site addition of clean water to produce a free flowing non-shrink repair micro concrete. The material is based on Portland cements, graded aggregates and fi llers, and additives which impart controlled expansion characteristics in the plastic state, while minimising water demand. The low water requirement ensures high early strength and long-term durability. For larger repairs, the mixed Silplast R20 may be modified by the addition of 5mm to 12mm clean, graded, saturated surface dry aggregates at site in ratio of 50-100%. can be applied in sections up to 100mm deep. For larger sections, the addition of approved aggregates may be required. This will depend on the specific configuration of the repair location For exceptionally large repairs contact with Silkon technical team.
Usages and Advantages
- Gaseous expansion system compensates for shrinkage and settlement in the plastic state.
- Can be pumped or poured into restricted locations. Highly fluid to allow for placement without vibration. Pre-packed to overcome site-batched variations.
- Rapid strength gain to facilitate early reinstatement.
- High ultimate strengths and low permeability of cured repair.
- Contains no chloride admixture.
- Ensures piletop integrity as part of a waterproofing system
