It is used to measure the drying shrinkage of autoclaved portland cement and potential expansive reactivity of Cement aggregate combinations in mortar bars during storage on self-drying.The instrument consists of chanelled base over which two vertical pillars are fixed. An adjustable cross plate is at the top. A dial gauge, reading to 0.002 mm x 12 mm or 0.01 X 25mm is fixed to the top. The plunger end of the dial Gauge can be located up on a 6.5 mm. dia ball or other reference point cemented in the specimen. On the base there is a similar recessed seating in which can be placed a second ball or reference point in the specimen.Complete with a stainless steel standardiation bar with insulated grip and with 6.5mm dia ball mounted in the ends.

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 plate and a recessed seating and a 300 ± 1.0 mm long alloy steel reference bar having coefficient of thermal expansion less than 2x10-6deg with 6 mm dia steel balls mounted at the ends. Supplied complete, with a dial gauge 0.002 mm x 10 mm.
