متن کاملCement hydration: building bridges and dams at the microstructure level
The concurrent goals of cement hydration are to percolate (bridge) the original cement particles into a load-bearing network and to depercolate (dam) the original water-filled capillary porosity. The initial volume, particle size distribution, and flocculation/dispersion state of the cement particles have a large influence on both hydration rates and microstructure development. Likewise, the ca...
متن کاملDetermining the water - cement ratio , cement content , water content and degree 1 of hydration of hardened cement paste : Method development and validation on 2 paste samples
7 We propose a new method to estimate the initial cement content, water content and free water/cement ratio (w/c) 8 of hardened cement-based materials made with Portland cements that have unknown mixture proportions and 9 degree of hydration. This method first quantifies the composition of the hardened cement paste, i.e. the 10 volumetric fractions of capillary pores, hydration products and unr...
متن کاملObservation of dynamic crossover and dynamic heterogeneity in hydration water confined in aged cement paste
High resolution quasi-elastic neutron scattering is used to investigate the slow dynamics of hydration water confined in calcium silicate hydrate gel in an aged cement paste at supercooled temperatures. A super-Arrhenius to Arrhenius dynamic crossover of the average translational relaxation time 〈τ 〉 as a function of the inverse temperature is observed at TL = 231 ± 5 K, which coincides with a ...
متن کاملMechano-Physical Properties and Microstructure of Carbon Nanotube Reinforced Cement Paste after Thermal Load
The article presents the results obtained in the course of a study on the use of carbon nanotubes (CNTs) for the modification of a cement matrix. Carbon nanotubes were introduced into a cement paste in the form of an aqueous dispersion in the presence of a surfactant (SDS-sodium dodecyl sulfate), which was sonicated. The selected physical and mechanical parameters were examined, and the correla...
