TL;DR: In this paper, the authors quantify the ageing effect on the rheological characteristics of bituminous mortars and apply it in evaluation of the ravelling resistance of PA wearing courses.

TL;DR: In this paper, the pore size distribution of CA mortars presented three peaks and the peaks did not shift with water-to-cement (W/C) ratio and asphalt to cement (A/C), but got higher with the increase in W/C ratios.

TL;DR: In this article, several nanomaterials have been used in cementitious matrices: carbon nanofilaments (either multiwall nanotubes or nanofibers), nanosilica and nanoclays.
Abstract: In this work, several nanomaterials have been used in cementitious matrices: carbon nanofilaments (either multiwall nanotubes or nanofibers), nanosilica and nanoclays. The physico-chemical behavior of these nanomaterials at three different levels has been analyzed: cement paste, mortar and concrete. It has been determined the setting times, the workability, the mineralogical structure and the dispersion of the nanomaterials in the cement matrix by ESEM/EDX , the percentage of hydration by TGA and the mechanical properties of mortar and concrete at 3, 7, 28 and 56 days. It has been found that almost all the nanomaterials used in this study accelerate the hydration process (with a proper dispersion), obtaining reinforcements in compression and flexural strength at 3 and 7 days (between 20 and 40 %). At 28 days, it has been observed that carbon nanotubes and nanofibers exhibit a reinforcement in the flexural strength (more than 25%), due to their fibrilar structure. Reinforcements, either in compression or flexural strength, have been reached with nanosilica (between 20 and 40 %); indeed, pozzolanic activity has been confirmed with nanosilica.
