Injections of reinforcement and reinforcement of concrete, masonry, rock works etc. Anchoring and fixing of ties, electrowelded steel mesh, beam ends for construction joints etc. Sealing of post-tensioning sheathing. Creation of filling paddings in the spaces between conduits and excavation holes.
Application surfaces should be clean, free of soiling, crumbling and non-adhering parts, dust, etc., conveniently saturated with water until they reach the condition "saturated with dry surface". An adequate roughening of the surfaces by scarifying, sandblasting etc. is always necessary in order to obtain the maximum adhesion values to the substrate. The optimal values are obtained with high pressure hydro-scarification. Bare the irons undergoing disruptive oxidation or deeply oxidized, removing the rust of the exposed irons (by sandblasting or abrasive brushes).
Pour 2/3 of the total mixing water in the concrete mixer, gradually add the product and the remaining water, mixing until a homogeneous lump-free mixture of the desired consistency is obtained. Apply on-site by injection or pouring within 60' from mixing with water.
- Pour out
- Mixed walls (bricks and stones)
- Stone walls
Adopt casting procedures capable of ensuring the absence of discontinuities and air bubbles.
Do not use in the absence of adequate confinement.
Cure the protection and the moist hardening of exposed surfaces.
