Brick Construction Brick-lined construction can be used for many severely corrosive conditions under which high alloys would fail. Common bricks are made from carbon, red shale, or acidproof refractory materials. Red-shale brick is not used above 175°C (350°F) because of spalhng. Acidproof refractories can be used up to 870°C (1,600°F).

The capital of Maryland moved from St. Mary s City to Annapolis in 1696, and in 1704, the Chapel was ordered locked shut and never again used as a house of worship (3). Many of the buildings at the old capital were tom down soon after, and the construction materials utilized elsewhere. Of the major brick constructions at St. Mary s, only the State House remained until the 1840s, when the bricks were reused in the nearby Trinity Church (4). Bricks from the Chapel superstructure were likely reused at the Jesuit manor house at St. Inigoes, a few kilometers from the center of the city. Today, the site of St Maiy s City is a historical and archaeological park, with a museum and several reconstructed buildings. 

In phosphoric acid production plants, both red shale and fireclay brick have excellent resistance to all concentrations of phosphoric acid at temperatures up to 250°F, provided the acid contains no HF. If HF is present in the phosphoric acid, carbon brick construction must be used. As a rough rule-of-thumb, HF levels above 50 ppm in phosphoric acid require tank linings of carbon brick bonded and jointed with a carbon (or barytes) filled furan mortar over a suitable membrane to match the steel or concrete substrate structure. 

Monolithic refractories have lower thermal expansion than most refractory bricks. Whatever small expansion does occur can usually be absorbed by the supports. Therefore, unlike refractory bricks, monolithic refractory walls do not require clearances for thermal expansion. Clearances required for brick construction may allow passage for furnace gas leaks out or air into a furnace. The superior sealing capability and reduced expansion of monolithic refractories make them suitable for higher furnace... 

Here, its pressure capability is limited by its brick construction, and its ability to withstand higher temperatures is restricted by the low melting point of the V2O5 catalyst. If an alternative reactor, for example a catalytic plate unit, could be devised to overcome these limitations then the use of oxygen at elevated pressure would be well worth consideration. The attractive features of this approach are ... 

Mortar. Mortar serves several functions in brick construction. It holds bricks together, compensates for brick irregularities, and distributes load or pressure among the units. 

STERNCHEM Polyester Mortar is formulated to provide superior service for acid brick constructions in the chemical process, pulp and paper, plating, textile, fertilizer, and metal refining industries. They are especially suited for chlorine dioxide towers, bleaching vats, trenches, sumps, pits, bleaching solutions of sodium hypochlorite, oxidizing solutions of nitric and chromic acids to 20% concentrations, hydrobromic acid, potassium and sodium dichromates, bromine water, salt solutions to pH 11. 

STERNCHEM Phenolic Mortar is formulated to provide superior service for acid brick constructions requiring the chemical resistance of carbon/resinous phenolic systems.
