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 ...

Hierarchical meta-modelling of stone injected with CNT/cement mortar [PDF]
arXiv, 2023 This paper presents an innovative hierarchical meta-modelling approach for predicting the effective elastic properties of stone injected with composite cement grouts containing Carbon NanoTubes (CNTs) for structural rehabilitation purposes. The study first addresses the homogenization of the nano- and micro-scales through numerical representative ...

Self-desiccation and self-desiccation shrinkage of silica fume-cement pastes [PDF]
, 2017 Self-desiccation is one common phenomenon of high-performance cementitious materials, which are characterized by low water/binder (w/b) ratio and high mineral admixture incorporation. As a consequence, large magnitude of self-desiccation shrinkage, a key

Influence of MWCNT/surfactant dispersions on the mechanical properties of Portland cement pastes [PDF]
, 2017 This work studies the reinforcing effect of Multi Walled Carbon Nanotubes (MWCNT) on cement pastes. A 0.35% solid concentration of MWCNT in powder was dispersed in deionized water with sodium dodecyl sulfate (cationic surfactant), cetylpyridinium ...

Optimal cement paste yield stress for the production of stable cement foams [PDF]
Cement and Concrete Research (2019) 120, pp 142-151, 2019 Production of morphology-controlled cement foams remains challenging, mainly due to bubble stability issues during cement setting. The use of cement paste with high yield stress is expected to promote stability by damping intrinsic bubble kinetics. Here we show however that for given W/C ratio, fresh foam stability can be achieved instead by decreasing

Molecular dynamics modeling of the effects of cementation on the acoustical properties of granular sedimentary rocks [PDF]
arXiv, 2006 The incidence of cementation processes on the acoustical properties of sands is studied via molecular dynamics simulation techniques. In our simulations, we consider samples with different degrees of compaction and cementing materials with distinct elastic properties.
