PRODUCT DESCRIPTION

Renderoc LA55 Plus is supplied as a ready to use blend of dry powders which require only the site addition of clean water to produce a free-flowing, shrinkage compensated, micro- concrete suitable for large volume repairs at a nominal thickness in excess of 50 mm. The unique formulation of Renderoc LA55 Plus is based on supplementary cementitious materials (SCMs) making it environmental friendly. The formulation includes graded aggregates and additives, which minimises water demand, promotes high fluidity, ensures fast strength gain and long-term durability. A unique system controls plastic and long-term drying shrinkage. The aggregate grading is designed to aid uniform mixing and to eliminate segregation under pumping pressures. It’s low alkali content minimises the risk of alkali–silica reaction. The hardened product exhibits excellent thermal compatibility and very low water permeability. Uses:Renderoc LA55 Plus is ideal for the reinstatement of large, structural sections of concrete as well as for many smaller locations where difficulties of access make hand or trowel- applied mortars impractical. The highly fluid nature of Renderoc LA55 Plus obviates the need for compaction and vibration even where access to the repair zone is restricted or where reinforcement is congested. It is suitable for use where excellent chloride and carbon dioxide resistance is required or for repairs to concrete affected by alkali-silica reaction (ASR). Renderoc LA55 Plus is alkaline in nature and will protect embedded steel reinforcement.
