UltraTech Microkrete HS3
Polymer-enriched non-shrink micro-concrete for ~40 MPa repair and micro-concreting.
Product Overview
UltraTech Microkrete HS3 is a polymer-enriched, cement-based, non-shrink micro-concrete intended for general micro-concreting and structural repair, with a designed strength of around 40 MPa. Formulated with special polymers, additives and selected fillers, it is self-compacting and free-flowing, filling tight cavities and congested reinforcement without vibration while resisting bleeding and shrinkage. It is a cost-effective choice for slab repairs, light jacketing and routine concrete restoration where extreme strength is not required but durability and a void-free fill are. Coarse aggregate up to 8 mm may be added for larger sections. Part of the UltraTech Building Products range, it is available through Space Arc Engineering, an Authorized Project Distributor in India, for reliable supply to repair contractors and applicators.
Features & Benefits
- Designed strength of around 40 MPa for routine structural repairs
- Non-shrink fill that bonds tightly without cracking on cure
- Self-compacting flow reaches congested, hard-to-vibrate areas
- No bleeding and good consistency for dense, durable repairs
- Economical micro-concrete for general repair and concreting
- Accepts up to 8 mm coarse aggregate for higher-volume work
Technical Highlights
| Coverage | A 40 kg bag yields roughly 22–23 litres of micro-concrete at about 15% water/powder ratio (before added aggregate). |
| Strength | Designed compressive strength of around 40 MPa; tested to standards such as ASTM C109 and IS 5816. |
| Performance | Non-shrink, self-compacting and self-curing with good flow and strong bond to old concrete. |
| Application Conditions | Mix at about 15% water/powder ratio and place into clean, saturated-surface-dry formwork; up to 8 mm aggregate may be added. |
| Packaging | Supplied in 40 kg bags as a ready-to-mix powder. |
Applications
- General micro-concreting of concrete slabs and members
- Light jacketing and strengthening of columns and beams
- Patch repair of damaged or spalled reinforced concrete
- Filling of congested, hard-to-access reinforced sections
- Routine concrete restoration where ~40 MPa strength suffices

Frequently Asked Questions
What is UltraTech Microkrete HS3 used for?
It is a non-shrink micro-concrete for general micro-concreting, slab repairs and light jacketing, with a designed strength of around 40 MPa — the entry grade of the Microkrete range.
When should I choose HS3 over HS1 or HS2?
Choose HS3 for routine repairs where around 40 MPa is adequate. Step up to HS2 (~60 MPa) or HS1 (~80 MPa) when the structural specification demands higher strength.
Does Microkrete HS3 shrink as it sets?
No. It is a non-shrink micro-concrete, so it bonds tightly to the existing concrete without the cracking or pull-away associated with ordinary mortar.
Can aggregate be added to Microkrete HS3?
Yes. Coarse aggregate up to 8 mm can be added for higher-volume pours while maintaining flow and non-shrink behaviour. Refer to the TDS for dosage.
