Experiment 124. — Grind a gram of starch in a mortar with a little water to creamy consistency. Pour this into about 100 cc. of boiling water, and stir the hot liquid. Allow it to cool, or cool it by holding the vessel in a stream of cold water, and then decant the clear liquid. Use this starch solution to test for iodine. 

The liner plate lining of the underside of a concrete cover does not offer permanent protection. For one thing, there is no membrane between the liner plates and the concrete-only the layer of hot asphalt over the mortar joints. The liner plates are not as dense as, have a higher absorption than, acid brick-6% allowable-and they are thinner than acid brick, The absorption testing of liner plates is accomplished under ASTM C-301-by no means as stringent a test as that used for acid brick. Consequently, the economical life of this kind of a cover is limited. In vessels handling ambient temperature wastes, the cover may last a number of years. But if the vessel operates at an elevated temperature and contains a volatile corrosive such as hydrochloric acid, tile may start falling off in less than a year. In the past the only alternative was the same kind of covers used for steel tanks. 

The SCSS data also provide insight into the expansion allowance that the mortar joints provide. Table 2 uses the same data and shows the percentage of the compressive deformation that occurs in the 1.6-mm-thick mortar joint. As expected, greater deformations occur in the mortar joint at the higher levels of temperature and compressive stress applied to the mortar joint. It should also be noted that the compressive stress levels used in the SCSS tests are realistic based on field strain gauge measurements on cylindrical vessels lined with 70% fired alumina brick (6).
