Better performance of slag concrete exposing to high temperatures Concrete made with GGBS cement is much better than concrete made with 100% OPC at maintaining its compressive strength when exposed to high temperatures. OPC specimens heated to 400 °C or above have been shown to exhibit severe cracking to the point of disintegration after a […]

What is Cement Mixer Shot?
As a cement researcher, I know cement much better than average people, while it is not the case with everything with a name using the word “cement”. When I type “cement” in the powerful Google search box, Google automatically gives an alternative search phrase “cement mixer shot”, which means “cement mixer shot” is a very […]
In the cement science field, XRD analysis combined with Rietveld method can give quantitative results of crystalline phase of hydration products, so I try to use XRD/Rietveld method to quantify the hydration products of cementitous material. To achieve good performance of XRD test, fine powder is required and of great importance. The question is how […]
