چکیده

Vertical scanning interferometry and XPS show the reaction of CaCO3 with the hydration retarder nitrilo-tris-(methylene)phosphonic acid follows a pathway of dissolution of the calcium followed by precipitation of a calcium phosphonate; subsequent surface reorganization/restructuring of the calcium phosphonate exposes the underlying CaCO3 for further hydration.

The Surface Area of Cement Paste as Measured by Neutron Scattering - Evidence for Two C-s-h Morphologies

Small-angle neutron scattering was used to measure the effect of water-to-cement ratio (w/c) and cement batch variation on the surface area of ordinary Portland cement (OPC) paste after hydration for 28 days at room temperature, and to measure the development of surface area over the first three days of hydration at 30 ̊C. The 28 day surface area was found to increase with w/c ratio in proportio...

Investigation of the effect of phosphate agent type on setting time, flowability, hydration and dehydration of magnesium phosphate cement.

Magnesium phosphate cements (MPC) are the most developed kind of chemically bonded ceramics which form through the reaction of magnesium oxide and soluble phosphate salts. Therefore, study of different magnesium phosphate cement systems is considered important according to the type of phosphate agent used. In this study, effect of mono-ammonium phosphate (MAP), di-ammonium phosphate (DAP), and ...

Influential Mechanisms and Potential Applications of Nano-Silicas in Cement Composites

Nanosilicas have been known as super-pozzolanic materials and compared to silica fume, these materials have higher purity of silica and finer particles. However, in contrast to silica fume, nanosilicas are produced by various methods, leading to different morphologies and agglomeration statuses in their initial form. On the other hand, due to several mechanisms such as the bridging effect of ca...

Design and synthesis of macrocyclic ligands for specific interaction with crystalline ettringite and demonstration of a viable mechanism for the setting of cement

Cementitious materials are among those most widely used by mankind while being among the least well understood. The detailed physicochemical processes involved in the hydration and setting of cement slurries are very complex, and a clearly defined quantitative account is still lacking; indeed, even the composition of the cement powder itself is not known exactly. Still less has there been any u...

Mechanical Properties and Structures of Oil-well Cement Stone Reinforced with Siliceous Whisker

To fully utilize the siliceous whiskers and improve the mechanical properties of oil-well cement, the cement composites with different additions of siliceous whiskers were prepared, and analyzed by means of scanning electron microscopy (SEM), mechanical testing, X-ray diffraction (XRD), and infrared spectrum analysis. The results showed that the addition of 2% siliceous whiskers could slightly ...
