Renderoc LA55 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, shrinkage compensated micro-concrete suitable for large volume concrete repairs at nominal thicknesses in excess of 50 mm. The material is based on Portland cement, graded aggregates and additives which impart controlled expansion in both the plastic and hardened states while minimising water demand. Its low alkali content minimises the risk of alkali-silica reaction. The hardened product exhibits excellent thermal compatibility with concrete and outstanding water repellent properties. The aggregate
grading is designed to aid uniform mixing and to eliminate segregation under pumping pressures. The low water requirement ensures fast strength gain and long-term durability.
Uses
The highly fluid nature of Renderoc LA55, means that compaction and vibration are not required. Renderoc LA55 provides excellent chloride and carbon dioxide resistance and prevention of concrete affected by alkali-silica reaction (ASR). This makes the product ideal for the following uses:
- Reinstatement of large, structural sections of concrete. e.g. Marine structures, bridge columns and beams.
- Small locations where difficulty of access make hand and trowel applied application impractical. e.g. Honey combing on precast concrete segments, light railway wall repairs or concrete contaminated by salt water.
- As a repair mortar where cathodic protection systems are being used.
Advantages
- Dual expansion system compensates for shrinkage in the plastic and hardened states
- Low alkali content minimises risk of alkali-silica reaction
- Exceptional bond to concrete substrates without independent primer
- Suitable for placement by pumping or pouring techniques into restricted locations
- Self-compacting nature eliminates honeycombing and displaces air without vibration
- High strength and low permeability provide maximum protection against carbon dioxide and chlorides
- Pre-bagged to overcome site-batched variations - only the site addition of clean water is required
- Contains no chloride admixtures
