Local structure and Ca/Si ratio in C-S-H gels from hydration of blends of tricalcium silicate and silica fume
(Elsevier, 2021-03)
At the microscale, C-S-H gels from alite, or neat Portland cements, has a Ca/Si ratio close to 1.80. At the nanoscale, C-S-H is described by a defective tobermorite structure which allows a maximum Ca/Si ratio close to ...
Portland cement pastes analysed by synchrotron and laboratory X-ray imaging
(2020)
Portland Cement (PC) is the most used construction material and the derived building materials have very complex hierarchical microstructures. Quantitative characterization of their microstructures is of paramount importance ...
