Fracture measurements on cement paste
Journal of Materials Science, 1976This paper describes an investigation into the fracture behaviour of hardened cement paste. Notched specimens of the material were tested to failure in flexure and tension. In the initial flexural tests on beams of fixed overall depth, the stress intensity factor at failure as calculated from linear-elastic fracture mechanics appeared to be a material ...

Heat deformations of cement paste phases and the microstructure of cement paste
Materials and Structures, 1984The paper presents the results of an experimental investigation of the influence of thermal deformations of phases present in hardened cement paste on its microstructure. For the observation of the thermal deformation course in the range of temperature20–800°C, a method of complex thermal analysis (DTA, DTD, TD) was employed.

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 ...

Dielectric amplification in cement pastes
Advanced Cement Based Materials, 1997Dielectric amplification (dielectric constants >80) is observed in cement pastes at early ages. Standard nonlinear least squares fitting routines yield artificially large “capacitances” when constant phase elements are employed. Instead, capacitance vs. frequency analysis provides reliable evidence of dielectric amplification.

Permeability Measurenents On Cement Paste
MRS Proceedings, 1988AbstractThe permeability of cement paste to water was determined by using a triaxial permeability cell. A new technique of specimen conditioning, based on cyclic flow reversal, was used for the early attainment of equilibrium flow conditions. Effects or cement type, age, and silica fume addition, were investigated.

In some remote areas or islands, the shortage of freshwater inspires the consideration of using seawater for making concrete. However, the use of seawater is not common and relatively little research has been done on seawater concrete.

Construction and Building Materials, 2019
In this study, the mechanical and damping properties of montmorillonite (MMT)/organo-modified montmorillonite (OMMT) reinforced cement paste were investigated. The damping properties were measured by dynamic mechanical analysis (DMA).

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)

Cement & Concrete Composites, 2019
Nowadays, polycarboxylate (PCE) superplasticizer and polypropylene fiber (PPF) are widely used to improve the flowability and ductility of modern concrete. In this study, the rheology and flowability of cement paste with PPF have been investigated.
