The development of biomaterials capable of driving dental pulp stem cell differentiation into odontoblast-like cells able to secrete reparative dentin is the goal of current conservative dentistry. In the present investigation, a biomembrane (BM) composed of a chitosan/collagen matrix embedded with calcium-aluminate microparticles was tested. The BM was produced by mixing collagen gel with a ch...

The differences between the hydration of Portland cements with single and mixed sulfate carriers in presence triethanolamine (TEA) were investigated, possible mechanisms proposed. Without TEA, different types (gypsum, hemihydrate, anhydrite, mixture these) have a comparable process at same molar amount calcium sulfate. At TEA dosage 0.5 wt.%, sample three shows substantially stronger retardatio...

Concretes, depending on their application, may be exposed to elevated temperatures during lifetime, especially when placed near or in a furnace an accidental fire. The thermal stability of alkali-activated mortars and hydrated prepared using ladle slag two different aggregates was studied. A commercial calcium aluminate cement used as comparison for the properties after exposure up 1000°C. All ...
