Adiabatic concrete calorimeter 78–PV31A16

Adiabatic concrete calorimeter
Brand/Supplied From : Controls – Italy
Model : 78 – PV31A16
Standard : EN 12350-7, ASTM C231, AASHTO T152

ASTM C231 [This test method covers determination of the air content of freshly mixed concrete from observation of the change in volume of concrete with a change in pressure.]

Main Features :

Real time measurement of heat of hydration of 150mm concrete cube during hardening
​Reliable evaluation of the heating process inside massive concrete castings
Calorimeter cell with minimized heat loss from the concrete sample for true adiabatic conditions
Evaluation of the heat of hydration taking into consideration the temperature reached by the concrete

General Descriptions :
When concrete is curing and hardening, the hydration reaction of cement develops a large amount of heat with an increase in temperature. The temperature rise accelerates hardening of cement however, if it is not properly dissipated, it can cause the arise of tensile stresses inside the concrete structure with the consequent appearance of cracks and reduction of mechanical properties.
This effect is encountered particularly in massive concrete castings, due to the limited heat dispersion, leading the behaviour closer to adiabatic conditions.

The isothermal and semi-adiabatic testing methods are consequently less representative and most commonly used for mortars and cement pastes, basically to compare the behaviour of different types of cements.

The adiabatic method is the only method allowing correct evaluation of the heating process inside massive concrete works.

CONTROLS is the only testing equipment manufacturer who developed in the late 80s, in partnership with the main research laboratories, the first industrial adiabatic concrete calorimeter, so far having been limited to few prototypes in reasearch centers.

Nowadays the equipment has been completely renewed with the latest technologies, including new electronics and PC software, ensuring high testing accuracy.
