Influence of recycled aggregates and carbon nanofibres on properties of ultra-high-performance concrete under elevated temperatures
Mohamed Amin,Ibrahim Hakeem,Abdullah M. Zeyad,Bassam A. Tayeh,A. M. Maglad,Ibrahim Saad Agwa +5 more
TL;DR: In this paper , the use of recycled coarse aggregate (RCA) as a replacement for 50% of the total natural coarse aggregate was investigated. And the results showed that the addition of fiber contributed to the improvement of the concrete properties.

Using nano-silica to improve mechanical and fracture properties of fiber-reinforced high-volume fly ash cement mortar
Jing Yu,Jing Yu,Min Zhang,Gengying Li,Gengying Li,Gengying Li,Jiao Meng,Christopher K.Y. Leung +7 more
TL;DR: In this paper, a series of experiments were carried out to evaluate the effect of nano-silica (NS) on the fracture and mechanical properties of polyvinyl alcohol (PVA) fiber-reinforced HVFAM, with the fly ash/binder ratio fixed at 50% by weight.

Average stress in matrix and average elastic energy of materials with misfitting inclusions
Trevor A. Mori,K Tanaka +1 more
TL;DR: In this paper, a method of calculating the average internal stress in the matrix of a material containing inclusions with transformation strain is presented. But the authors do not consider the effects of the interaction among the inclusions and of the presence of the free boundary.

A new approach to the application of Mori-Tanaka's theory in composite materials
TL;DR: In this paper, a reconsideration and reformulation of the Mori-Tanaka's theory in its application to the computation of the effective properties of composites is presented, which is a straightforward exposition and interpretation of the method which are different than those existing in previous formulations.

The Interfacial Transition Zone (ITZ) Between Cement Paste and Aggregate in Concrete
TL;DR: In this article, the authors describe the so called interfacial transition zone (ITZ) in concrete as the region of the cement paste around the aggregate particles, which is perturbed by the presence of the aggregate, and show that the higher porosity present initially is significantly diminished by the migration of ions during hydration.

Interfacial Transition Zone in Concrete
TL;DR: In this article, the formation mechanisms and the microstructure of the ITZ are described, and the local properties of the interfacial zone are reviewed: the mechanical and the transport characteristics of theITZ are discussed in relation to the porosity and connectivity of pores.
