However, cement is also a criticized material by the public, for its intensive CO2 emission from production process. The production of cement accounts for about 5-8% of the […]

Buoyancy Effect of TGA Experiment

What is Buoyancy Effect of TGA experiment? TGA (thermogravimetric analysis) is an important method to analyze the hydration products of cementitious materials. When a TGA test for cementitious materials sample is performed, the initial TGA curve may appears as such: As can be seen from the curve, the mass exceeded the original mass, which is […]
