The article presents the results of ''in situ'' tests of two new cement mortar floors that were made defectively in an important public building with a large area. The performed results of organoleptic tests and extensive strength tests, which are helpful in determining the causes of numerous and various defects in floors, were presented. It was observed that the source of the aforementioned causes is not only the failure to comply with the technological and technical conditions and requirements for laying a cement mortar mix and the execution of floors but also the lack of appropriate supervision over the entire flooring process. The causes of defects were determined and should help to avoid similar situations in the future.

“…The patch grabbed textures were created with the use of a flooring trowel with different square sizes (Nos. [10][11][12], and also with a 2 mm rotated corrugated nylon tube along the concrete substrate surface (No. 9).…”

This paper describes a study conducted to evaluate the effect of texturing of the surface of concrete substrate on the pull-off strength (fb) of epoxy resin coating. The paper investigates a total of seventeen types of textures: after grooving, imprinting, patch grabbing and brushing. The texture of the surface of the concrete substrate was prepared during the first 15 min after pouring fresh concrete into molds. The epoxy resin coating was laid after 28 days on hardened concrete substrates. To investigate the pull-off strength of the epoxy resin coating to the concrete substrate, the pull-off method was used. The results were compared with the results obtained for a sample prepared by grinding, normative minimal pull-off strength values and the values declared by the manufacturer. During this study twelve out of fifteen tested samples achieved a pull-off strength higher than 1.50 MPa. It was found that one of the imprinting texturing methods was especially beneficial.

“…The researchers analyzed the ways of modification of industrial floors, which play a very important role in industrial construction. It is particularly important to ensure continuous use of the floor, because any functional defect and subsequent damage to the structure can cause difficult repairs [12]. An important aspect in floors design is the use of a suitable coating to finish their top layer.…”

Due to their numerous advantages, epoxy resin coatings are a common way to finish industrial floors. Obtaining coating strength at the level declared by the manufacturer requires preparation of the cement substrate through mechanical treatment, for example, in the form of sandblasting. The next step is the thorough cleaning and vacuuming of the surface and the application of the adhesives. The aim of this research was to improve the strength parameters of a coating in which no adhesive were used. materials which have a potentially positive effect on epoxy resins are mineral additives. This paper presents the results of tests aimed at improving the adhesion between a concrete foundation and an epoxy resin coating modified with waste glass powder obtained from the production of glass microspheres.
