Approximately 1700 kg of GROUT MICRO-J for every cubic metre of mixture to be made.
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 into the mixer, gradually add the product and, subsequently, the remaining water, mixing until a homogeneous mixture of the desired consistency is obtained. GROUT MICRO J can be mixed with different consistencies, from plastic to self-leveling pourable. With 12-13% of water (3.0 - 3.25 liters / 25 kg bag) plastic consistencies are obtained, with 13-14% (3.25-3.5 liters / 25 kg bag) consistencies castable, with 14-15% (3.5-3.75 l / 25 kg bag) self-leveling fluid consistencies. Small-volume doughs can be mixed with a double / triple helicoid whisk equipped with a speed regulator. Put in place by injection or pouring within 60 '30' of packaging. If the temperature, at the time of application, is between 0 and 5 ° C, the development of mechanical strength will be slower. It is recommended, with cold temperatures, to use lukewarm mixing water between 20 ÷ 30 ° C. If the temperature, at the time of application, is between 30 and 35 ° C, it is advisable to use mixing water at a low temperature (5 ÷ 10 ° C) and to apply the product in the coolest hours of the day (indicatively morning or evening).
