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: A typical TGA test result shows the buoyancy effect. Portland cement past, w/c=0.4, cured 1 […]
