Reinforcing effects of graphene oxide on portland cement paste
, 2015In this experimental study, the reinforcing effects of graphene oxide (GO) on portland cement paste are investigated. It is discovered that the introduction of 0.03% by weight GO sheets into the cement paste can increase the compressive strength and ...

The hydration of Portland cement
Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1978Electron microscopy and conduction calorimetry have been employed to study the hydration of Portland cement.In situstudies of wet cement pastes in an environmental cell in the high voltage microscope confirm that the reaction involves two stages: (a) the rapid initial formation of gelatinous hydrate coatings around the cement grains and, (b) after a ...

This chapter is composed of five sections: 2.1. Portland cement clinker burning, 2.2. The phase systems important for cement chemistry, 2.3. The clinkering process in industrial mixes, 2.4. Thermochemistry of clinkering process, 2.5. Phase composition of Portland cements. Clinkering process can be divided in two stage: the reactions in the solid state,
