This equipment is required to determine the heat of hydration of
cement as expressed in calories per gram.The equipment comprises
of the following :
1) A wide mounted double walled vacuum flask
with a stop cock 38 mm & a insulating container for the flask
2) A Beckman thermometer (Range 5° 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.
3) A constant speed stirrer (double bladed
propeller type)extended to within 38 mm from the bottom of the
flask.
4) A funnel (Gooch type)with a stem of 6 mm inner dia & a body
approx 25 mm long and 25 mm dia is fitted to the cock stopper for
introducing the sample All the above to combine to form the
calorimeter for the determination of heat of hydration of cement.
Suitable To Operate on 230 V A.C. 50 Hz
