Premixed calcium–phosphate cement pastes

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2003
AbstractA self‐hardening calcium–phosphate cement (CPC) containing Ca4(PO4)2O and CaHPO4 has been shown in clinical studies to be efficacious for repairing bone defects. This and several other similar CPCs harden in 10 min with the use of a phosphate solution as the liquid and form hydroxyapatite (HA) as the product.

Cement paste–epoxy adhesive interactions

Construction and Building Materials, 2011
In the field of civil engineering, the durability of concrete assemblies using adhesives is widely conditioned by the properties of the interface between the resin and the mineral support (concrete). In this context we studied first the molecular interactions at the interface between an epoxy resin and cement pastes by several approaches based on XPS ...

Controlling the Cohesion of Cement Paste

Langmuir, 2005
The main source of cohesion in cement paste is the nanoparticles of calcium silicate hydrate (C-S-H), which are formed upon the dissolution of the original tricalcium silicate (C(3)S). The interaction between highly charged C-S-H particles in the presence of divalent calcium counterions is strongly attractive because of ion-ion correlations and a ...

Cement Paste and Concrete

Annual Review of Materials Science, 1973
This paper outlines the current state of knowledge as regards the chemical and physical aspects of the structure of hardened cement paste, then relates the properties of shrinkage, inelastic behavior, and creep to structure. Some significant recent developments in materials for concrete production are presented.

Autoclaved compressed cement pastes

Cement and Concrete Research, 1975
Abstract Cement pastes, prepared by high-pressure compaction, were autoclaved under several experimental conditions. The results obtained are compared to those for water-cured compacted pastes.

Cement paste and concrete hardening under strain: I. Cement paste research

Cement and Concrete Research, 1995
Abstract This paper describes cement systems (paste, concrete, etc.) hardening under strain (HUS) when those systems get additional strength through adjusted stresses. The fundamental physical and chemical processes and the results of their research are given in the abstract with the mechanism of cement systems HUS.
