High performance, free flowing, low alkali micro-concrete.
Low alkali micro-concrete for the reinstatement of concrete, where low permeability characteristics are required and where high compressive strength is a consideration. It is a blend of Portland cements, graded aggregates, lightweight fillers and chemical additives to which a controlled amount of clean water is added in situ.
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) and can typically be applied in thicknesses between 50–150 mm. It conforms to the requirements of Highways Agency Specification for Highways, Class 29F.
Contains no chloride admixtures
Extremely low permeability to water, carbon dioxide and chlorides
Maximum compatibility with concrete of compressive strength 30–60 N/mm²
Suitable for use with cathodic protection systems
