Description
Langavant calorimeter for the heat of hydration of the cement method consists of introducing a fresh cement specimen into an isolated Dewar flask and monitoring the temperature changes within the specimen during the first early days.
After a certain time, the heat of hydration of the cement content in the sample is equal to the sum of the heat accumulated in the flask and the heat emitted to the environment during the test period.
The temperature of the mortar is compared with the temperature of an inert sample placed in a reference calorimeter flask.
The amount of heat achieved by the cement mortar is mainly dependent on nature thereof and may reach values between 10 ° C and 50 ° C.
The amount of heat is expressed in joules per gram of cement.
It consists of 2 isolated calorimeter bottles set 2 temperature probes to type PT-100 set with 3 threads, 50 disposable mortar box set and an electronics console with 4 measuring channels, and RS232 output interface for connecting up to 4 calorimeter bottles to the PC.
