Fig.-2: Mortar bars placed in water
Fig.-3: Length comprator
Fig.-4: Climatic chambers The linear expansion of each specimen is obtained as follows Expansion, % = 100 x (Ln − L0) / l Where: Lo - Zero reading i.e. reading of prisms before placing it into sodium hydroxide solution Ln – Reading at each interval after placing it into sodium Hydroxide solution, where n represents the interval l - Distance between the ends of the gauge studs, measured to the nearest of 0.1 mm (5).
