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 ...
