Cementron: Machine Learning the Constituent Phases in Cement Clinker from Optical Images [PDF]
arXiv, 2022 Cement is the most used construction material. The performance of cement hydrate depends on the constituent phases, viz. alite, belite, aluminate, and ferrites present in the cement clinker, both qualitatively and quantitatively. Traditionally, clinker phases are analyzed from optical images relying on a domain expert and simple image processing ...

Yield stress of aerated cement paste [PDF]
Cement and Concrete Research 127 (2020) p105922, 2019 Yield stress of aerated cement paste is studied. Samples are prepared by mixing aqueous foam with cement paste, which allows controlling bubble size, gas volume fraction and yield stress of the cement paste. Two distinct behaviors are observed depending on the surfactant used to prepare the precursor aqueous foam: (i) For a surfactant with low ...
