CEM-CRETE
(Flowable mortar for repairs of damaged reinforced concrete members)
Description:
CEM-CRETE Micro Concrete is a ready-to-use dry powder which requires only addition of clean water at site to produce a free flowing non shrink repair micro concrete. It is composed of good quality cement, properly selected aggregates & additives. It is used & designed for repairing of damaged reinforced concrete elements like columns, beams & structure where the areas are restricted or not easily accessible for proper placement of concrete using vibrator. CEM-CRETE Micro Concrete has excellent flowability, workability & proper particle size to reach small & congested reinforcement.
Areas of Application:
- Repair of damaged reinforced concrete elements like beams, columns, walls, etc. where access is restricted and compaction is not possible.
- For Jacketing of RCC columns to increase load-taking capacity (strengthening of vertical members)
Features & Benefits:
- Pumpable – Can be pumped or poured into restricted locations.
- Flowable – Flowable mortar hence does not require compaction.
- Shrinkage compensation – Controlled expansion system which compensates for shrinkage and settlements in the plastic state.
- Strength – Develops high initial and ultimate compressive strength.
- Moisture Resistant – Offers excellent resistance to moisture ingress.
- Durability – Makes repaired sections highly durable & compatible to parent concrete.
- Thickness build up – Can be applied at 100 mm thickness at one stroke.
Precautions & Limitations:
- CEM-CRETE Micro Concrete can applied in section upto 100 mm depth.
- For thickness more than 100 mm, addition of pre-calculated aggregates may be required.
- Strictly follow water-powder ratio as specified.
- Ensure that the shuttering is 100% watertight.
- Ensure full exposure of reinforced steel.
- Consult structural engineer if the diameter of rebar is reduced by more than 20% than the original diameter.
- Replacement or provision of addition steel shall be come in consultation with a structural consultant.
