Both epoxy-coated and zinc-coated steel bars are permitted to use in masonry structures and they may be utilized when corrosion-protected reinforcement is specified as per the design. Masonry is a heterogeneous material that consists of units and joints. On the contrary, bars covered with zinc coats do not need to increase the development length because zinc provides the same property as uncoated bars. Masonry structures are those structures which are built from individual units laid in and bound together by mortar. Some traditional materials, like solid brick (>10% of construction materials market) are still used, but autoclaved aerated concrete (AAC) and cement-sand calcium-silicate (Ca-Si) elements with thin joints are prevailing (>70% of the market) on the Polish market.
