Hydration of Cement Pastes Using the Cement LC3
2019Nowadays, cement is still one of the most consumed products in the world, and has grown more significantly. Thus, the use of supplementary cementitious materials (SCMs) to some extent reduces the carbon dioxide (CO2) emissions in the environment, contributing to the formation of a sustainable cement. In this context, Limestone Calcined Clay Cement (LC3)

Premixed calcium–phosphate cement pastes
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2003AbstractA 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.

Surface magnetic relaxation in cement pastes
Magnetic Resonance Imaging, 1994Surface magnetic relaxation in porous media is usually attributed to hindered rotation or to paramagnetic impurities on the surface. In cement pastes, however, it seems reasonable to attribute surface relaxation to dipole interactions in water adsorbed as water of hydration on grain surfaces.

The Properties of Cement Paste
2014In Chapter 5 the following issues are presented: Rheological properties of concrete, Relationship between the microstructure and strength of cement paste and Deformation of the paste. Cement paste is a Bingham fluid and shows as a rule the thixotropic behaviour. The flow of the paste can be relatively well presented by several models from which Bingham

Smart cement paste with carbon nanotubes
2016Carbon nanotubes can be added to cementitious materials to create a multifunctional nanocomposite with excellent piezoresistive and strain-sensing properties. The use of carbon nanotubes provides high strain sensitivity and signal-to-noise ratio, which are ideal for fabricating self-sensing nanocomposite cement paste for applications to structural ...

Influence of cement constitution and temperature on chloride binding in cement paste
Advances in Cement Research, 2000This paper describes effects of cement constitution and temperature on chloride binding in cement paste, which is an important subject in relation to lifetime modelling of reinforced concrete structures. The influence of cement constitution on chloride binding is investigated by substituting cement with pure cement clinker.

Using Dehydrated Cement Paste as New Type of Cement Additive
ACI Materials Journal, 2013This paper presents an experimental study, including evaluation and modification, on using dehydrated cement paste (DCP) as a new type of cement additive. After a series of processes, normal DCP (N-DCP) was produced as before and a modified form of DCP (M-DCP) was produced as well. The cementitious characteristics of the groups with different kinds and

Cement paste stratification at critical cementing point
The relevance of this research is driven by the necessity to investigate and predict the technological parameters of grouting mixtures in conditions that closely resemble real-world scenarios. The subject of this study is a grouting compound used in well construction, which serves to ensure the adhesion between the casing and the formation, strengthen ...Kovalchuk, Vlada +2 more

Cement paste and concrete hardening under strain: I. Cement paste research
Cement and Concrete Research, 1995Abstract 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.
