Description :

Sikacrete®-700 LA Repair is a cement-based, polymermodified, low-alkali, one-component, high-strength, deep-fill micro-concrete with non-shrink properties.
The mixed mortar produces a flowable repair mortar suitable for pouring applications, meeting the requirements of Class R4 of EN 1504-3. Due to its low resistivity,
the Product can be used with cathodic protection systems, and can be applied in single layer thicknesses up to 700 mm.

Uses : 
 

• Highway works (particularly suited to motorway bridge repairs).
• Repairs to structural concrete.
• Protection of corroded and damaged reinforced concrete.
• Refurbishment of soffits to bridge beams and crossheads.
• Cathodic protection projects.
• Creating concrete elements (e.g. beams, columns, or underpinning properties).
• Grouting under baseplates.
• Large volume repairs with congested reinforcement or restricted access.
• Deep fill applications (application layer thickness 15 to 700 mm).

Characteristcs & Advantages

• One-component, ready to use. Polymer modified for improved adhesion and performance.
• Easy to mix and apply.
• Good early compressive strength (~20 N/mm2 at 1 day).
• High final compressive strength (~80 N/mm2 at 28 days).
• Non-shrink (in both plastic and hardened states).
• Repair depths up to 700 mm in one application
• Self-compacting (vibration not required). Uses aggregates which are not susceptible to Alkali- Silica Reaction (ASR).
• High tensile adhesion / bond strength negating the need for a bonding primer.
• Suitable for use in conjunction with cathodic protection (low resistivity).
• Low chloride content enabling it to be used in contact with steel.
• Can be placed under gravity or pumped.
• Relatively long working life to permit larger volume applications.
  EN 1504-3 Class R4.
• Reaction to fire: EuroClass A1.
