High-Strength Micro-Concrete for Structural Repairs
A versatile, flowable, high-strength, non-shrink cementitious micro-concrete for repairs is called STRUCTURE GUARD. It is made up of corrosion-resistant additives, carefully chosen aggregates, and high-quality cement. It is used and made to repair damaged reinforced concrete components, such as beams, columns, and structures, in places that are too small or difficult to reach for a vibrator to properly put concrete. It is suitable for thicknesses up to 40 mm to 100 mm and flows freely.
