Length Comparator
IS 1199-1959, IS 4031 1968 BS 1881, ASTM C 151, C490.
It is used to measure the dying shrinkage of concrete autoclave expansion of Portland cement and potential expansive reactivity of cement aggregate combinations in mortar bars during storage, on self-drying.
Specification:
The instrument consists of a channeled or a round base over which two vertical pillars are fixed. An adjustable cross plate is at the top. A dial gauge, reading to .002mm x 5mm. Can be located upon a 6.5mm. dia ball or other reference point cemented in the specimen. On the base there is similar recessed seating in which can be placed a second ball or reference point in the specimen.
Complete with a stainless steel standardization bar with insulated grip and with 6.5mm dia. Balls mounted in the ends. The unit can be supplied with an Electronic Dial Gauge at extra cost if indicated at the time of placing the order.

Specification:
This equipment is required to determine the heat of hydration of cement as expressed in calories per gram.
The equipment comprises of the following:
- A wide mounted double walled vacuum flask with a stop cock 38 mm & a insulating container for the flask
- A Beckman thermometer (Range 5o C) held tightly by the cock stopper in such a way as to avoid accidental contact with the stirrer blade & the reading lens. To facilitate the easy removal the cock stopper is in two halves.
