Furan resins have also been extensively used in formulating mortars, grouts, and ‘‘setting beds’’ for brick lining destined to be exposed to highly corrosive environments, such as concentrated acids or highly alkaline cleaning solutions [3,16,60-62]. Two techniques are used in order to realize assemblies, namely tilesetter’s and bricklayer’s methods. The first method is based on the use of quarry tiles or pavers with smooth surfaces. The second method consists in using acid-resistant brick linings. Depending on the end use, three types of bricks are used for the installation of this type of assembly, namely:
(i) Red shale bricks which have the highest resistance to chemical attack. They are relatively fragile towards thermal and mechanical shocks. Typically, standard brick dimensions are 20.3 cm by 9.5 cm.
(ii) Fire clay bricks which are less resistant to chemical attack, but much more stable against thermal and physical shocks. Their standard dimensions are 22.8 cm by 11.4 cm.
(iii) Carbon bricks which are used to withstand hydrofluoric acid, fluoride salts, and hot, strong alkaline media. They are also very resistant to thermal shocks.
In 1990, 2 was also used in order to prepare low temperature (—10°C) hardening epoxy resin mortar adhesive [63]. For this, 2 was added as a reactive diluent to classical epoxy resin based on bisphenol A and the adhesive thus obtained was found to have good mechanical properties. These compositions are presently being produced by the Chinese Yanan Chemical plant. More recently, 2 was used in polymer compositions in building and structural repairs and showed properties similar to those obtained with epoxy resins [64].
