CEMENT & CONCRETE HYDRATION ANALYSIS

Cement & Concrete Hydration Analysis as per ASTM C1702 and ASTM C1679

The TAM Air is a flexible, sensitive analytical platform that is an ideal tool for large-scale isothermal calorimetry experiments. Capable of measuring several samples simultaneously under isothermal conditions, the TAM Air with its air-based thermostat and easily interchangeable 8-channel standard volume or 3-channel large volume calorimeters, is especially well-suited for characterizing processes that evolve or consume heat over the course of days and weeks.

TAM Air the Isothermal calorimetry

The TAM Air the Isothermal calorimetry is an excellent tool to measure the total heat of hydration as well as to continuously follow the reaction rates in the different phases of the complex cement hydration process.

The heat flow profile from a hydrating cement or concrete sample is information-rich and can give insight and knowledge for:

The development of new cements and admixtures
Dosing and formulation optimization
The impact of temperature on the hydration process
The detection of any incompatibility of materials
Production and quality control

The new TAM Air from TA Instruments is a powerful isothermal calorimeter with heat flow sensitivity in the microwatt range and unmatched baseline drift performance.

TAM Air from TA

New TAM Air Advantages include

Operating temperature range: 5 °C – 90 °C
Circulating air thermostat with temperature stability at ±0.001 °C
Updated electronics for accurate data acquisition and EU ROHS compliance
User choice of 8-channel or 3-channel calorimeter configuration
Improved baseline drift performance for long term (e.g. weeks) experiments
Connect up to 8 external probes including I/O Voltage card
Compatible with all current TAM Air ampoules
Operates with complete TAM IV Lab Asst. software

All calorimetric channels are of the twin type, consisting of a sample and a reference chamber. The 8 channel calorimeter will accommodate ampoules with a 20 mL volume. The 3 channel calorimeter will accommodate ampoules with a 125 mL volume. The TAM Air is the recognized instrument of choice in the research and development, as well as quality control process of cement and concrete. With the higher volume ampoules in the 3-channel calorimeter, the TAM Air can also be utilized in food and environmental science applications
