Self-healing characteristics of fracture in sealing materials based on self-healing effect
Meitan xuebao, 2023 Cement-based materials are the most commonly used grouting and sealing materials in underground coal mines, but due to the effects of stress perturbation as well as water loss and shrinkage of cementitious materials, the traditional cementitious ...

In vitro studies of calcium phosphate silicate bone cements
Journal of Materials Science: Materials in Medicine, 2012 A novel calcium phosphate silicate bone cement (CPSC) was synthesized in a process, in which nanocomposite forms in situ between calcium silicate hydrate (C-S-H) gel and hydroxyapatite (HAP). The cement powder consists of tricalcium silicate (C(3)S) and calcium phosphate monobasic (CPM).
