The Importance of Cement and its Future

Concrete is the most used material in the world because of its cheap price and large quantity. It is needless to say concrete is made of cement. 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: A typical TGA test result shows the buoyancy effect. Portland cement past, w/c=0.4, cured 1 […]

What is density? how to distinguish different density definitions?

As material researchers, we know density is the physical property of materials. Even since grade school, we are taught that density is simply the mass of an object divided by its volume. However, this is pretty complicated in the case of cementitious materials. The mass of a certain amount of harden cement (or concrete) paste […]
