Ultracrete QC10 Rapid Strength Concrete

QC10 Rapid Strength Concrete, is a fast set mortar that has been designed for thick section repairs, haunching reinstatements, ironwork backfilling and commercial sign and post installation.

QC10 Rapid Strength Concrete has been HAPAS approved since 2005 and can be open to traffic in just 2 hours.

Features and benefits of QC10

  • Contains special cements and graded aggregate
  • Simply add water on site to form a high strength concrete
  • Suitable for applications from 30mm – 250mm in one pass
  • Can be bulked out in certain applications (may affect performance)
  • Approved for use on the London Underground and Overground
  • NBS Plus registered for ease of specification

Technical information

  • Workability: 5 – 10 minutes
  • Set time: 10 – 20 minutes
  • Depth: 30mm – 250mm
  • 20N/mm² compressive strength in 2 hours
  • Size: 25kg bag
  • Cleaning: QC10 should be removed from tools and equipment with clean water immediately after use. Cured material can also be removed mechanically.
  • Storage: Store in closed original packaging at temperatures between 5°C and 30°C. Avoid frost.

How to prepare surfaces for QC10

All surfaces should be free from oil, grease, dust or any other visible contaminants before application.
  1. Remove all loose particles and work on a sound substrate.
  2. Pre-soak the area with clean water prior to application to aid bond.
  3. Remove ponded water before applying the product).

How to mix QC10 Rapid Strength Concrete

  • QC10 can be mixed mechanically or by hand.
  • If by hand, ensure that the mixing is vigorous.
  • Mix the inner bag containing the cement with the sand/aggregate.
  • Add approximately 1 litre of water and mix thoroughly.
  • Then, if required, add sufficient additional water until the required consistency is achieved to a maximum of 2 litres.
Note: It is essential that this product not be over-watered. The addition of excessive water will result in slower strength gain, reduced final compressive strength and the possibility of shrinkage cracking. Sand/aggregate contains moisture and the volume of water required will vary depending on the moisture content of the aggregate. Mix only enough material to apply within 4 minutes. Never remix or add water.

How to apply QC10 Rapid Strength Concrete

In conjunction with the HAPAS Approved UltraCrete Manhole Reinstatement System:
  1. QC10 should be applied with a float 40mm below the required surface, then compacted to ensure no voids are evident. The final surface should be rough floated to achieve a level surface.
  2. Once the material has reached an initial set all vertical edges of the reinstatement, including the ironwork, should be sprayed with UltraCrete SCJ. This will prevent the ingress of water into the reinstatement.
  3. Ensure all vertical substrates are fully covered.
In conjunction with thick section concrete repairs, haunching reinstatements, post, sign, fences and barrier erection:
  1. Apply material over pre-soaked area within 4 minutes of mixing.
  2. Firm well into position by tamping or using a float.
  3. Clean any mixing equipment with water immediately after use.
