in addition to traditional dry spraying machines, there are “wet” spraying machines ; These have a lower volume yield, but have a lower rebound and produce less dust than dry spraying. Therefore, they can be used for small areas or more delicate areas, where access is restricted or in closed environments. The most important criteria for the application of spray repair materials are minimal rebound and large layer thicknesses without sagging problems. Depending on the extent of the damage to the concrete, the preparation of the support can range from cleaning the surfaces to removing a layer of concrete of considerable thickness.
Therefore, the greater the existing damage, the more aggressive the surface preparation treatment will be. Damage that may be caused by the support's sanitation treatment itself must also be Antarctica Email List considered, such as cracks or detachment from the support. These must be corrected, eliminating or consolidating those areas. Once the concrete is prepared, it is recommended that it have a tensile strength of 1 N/mm2, that it be sound , clean and with an open pore surface (a roughness of 5 mm is recommended) to improve the adhesion between the old concrete. and repair material.
There are different sanitation procedures, both manual and mechanical. The choice of the appropriate method will depend on the extent of the damage (area and depth), the location (accessibility and position) and issues related to the safety and hygiene of the operators (for example, in poorly ventilated or unventilated places, it should be discard the application of sandblasting. This presentation will be attended by technicians, experts and industrial technical engineers , including the president of the General Council of the profession in Spain, José Antonio Galdón. With a focus on revitalizing depopulated areas and promoting industrialization, this pilot project could change the construction landscape in Spain. The push towards a Spain of opportunities begins in Zamora, but its ripples could spread to the entire country.
