Concrete - one of the most common building materials, the most frequent use of it finds in the precast-monolithic designs. Using this method, as a continuous concreting, provides high quality of the monolithic structures. But this is not always possible, therefore, in the construction of the project provides for construction joints. Construction joints are formed stops concreting during construction. In accordance with snip 3.03.01-87 before concreting the surface of construction joints, you need to clean concrete of dirt: dirt, oil, snow, ice, cement, tape, etc. Cleaning of concrete, namely the surface of construction joints, from the cement film is carried out for eliminate the possible formation of cold joints. " Especially important is the cleaning of concrete from the cement film.
There are various ways of cleaning concrete: mechanical milling and refining, processing, water or air jet and dry cleaning using cleaners concrete. To clean the layers must use a special concrete cleaner, because, for example, cleaning with using hydrochloric acid is technically unnecessary and harmful. Special cleaner concrete fashionable to use not only to clean construction joints, but the rest of the concrete surface. You just need to apply concrete cleaner on the surface with a brush or spray and leave for 2-10 minutes, depending on the degree of contamination, then rinse with cleaner water under high pressure. If heavily soiled
