Assessment of the effect of temperature on a cement paste by Thermal Gravimetric Analysis (TGA) (CAT#: STEM-ACT-0044-WXH)

Name: Assessment of the effect of temperature on a cement paste by Thermal Gravimetric Analysis (TGA)
SKU: STEM-ACT-0044-WXH
Rating: 5 (1 reviews)

Introduction

The concrete is mainly composed of cement paste and aggregates. Upon heating, the cement paste undergoes a continuous sequence of more or less irreversible decomposition reactions. Therefore, once heated piece of the specimen will behave for some time as a stable material up to the temperature of heating.

Principle

Thermogravimetric analysis or thermal gravimetric analysis (TGA) is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. This measurement provides information about physical phenomena, such as phase transitions, absorption, adsorption and desorption; as well as chemical phenomena including chemisorptions, thermal decomposition, and solid-gas reactions (e.g., oxidation or reduction).

Applications

• Thermal characterization of polymers.
• Determination of the composition of alloys and mixtures.
• Determining the purity and thermal stability of both primary and secondary standards.

Procedure

TGA analysis is performed by gradually raising the temperature of a sample in a furnace as weight is measured on an analytical balance that remains outside the furnace. Thermogravimetric analysis instrument measures the changes in a sample's weight in a particular temperature by enclosing the sample in an oven.
