The concrete production process is, contrary to appearances, relatively complicated. It is not enough to put all the necessary concrete mixture components in proper machines. It needs to be done in the proper order, remembering about the proper amounts of individual components and the compound preparation time. Each of these ingredients has a huge impact on the end characteristics of the composite. First, following the concrete specifications and appropriate research, […]
Concrete corrosion occurs wherever the surface of concrete or reinforcement is exposed to the effects of various kinds of destructive factors. Very roughly speaking, it is assumed that there are three types of concrete corrosion: physical, biological and chemical corrosion. Physical corrosion is caused primarily by processes related to concrete cavitation, abrasion and erosion, as well as water freezing in its pores. It is relatively easy to detect since it[…..]
Numerous factors have an impact on the final look of architectural concrete, i.e. its shape, texture and colouring. They include: – material-related factors, – design and structural factors, – technological factors. The components of concrete undoubtedly fall within material-related factors. Both the composition of the concrete mixture and its consistency are important. Choosing the proper cement is not without importance either. Using metallurgical cements (CEM III) gives concrete bright and[…..]
Reinforced concrete is a structural material consisting of concrete and reinforcement in the form of steel inserts. They can be bars, strings, cables, lines or nets, they can also be large cross-section rigid steel components (e.g. U-sections, I-sections, etc.) Using steel components in concrete is meant to increase its tensile stress strength. Concrete alone, with no added steel, is perfectly able to deal with compression stresses, but its tensile strength[…..]
