Length Comparator

Length Comparator

The apparatus can be used for three basic tests :

• Initial drying shrinkage : The difference between the length of the cured specimen and the length when it is dried.
• Drying shrinkage : The difference between the length of the specimen from existing structure and its length when completely dried.
• Moisture movement : The difference between the length of the dried specimen and its length when again saturated with water.
• The apparatus consists of a frame with adjustable cross head. The base is provided with a stainless steel circular platen having a recessed seating and a 300 to 301 mm long alloy steel reference bar having coefficient of thermal expansion less than 2 x 10-6 mm/degC with 6 mm dia steel balls mounted at the ends, Supplied complete, with a dial guage 0.002 mm x 10 mm.
