TL;DR: In this article, thermogravimetric, energy dispersive X-ray, differential thermal, and powder Xray diffraction analyses were performed on a set of commercially available reactive MgO and fine recycled concrete aggregates.
Abstract: In this paper, mortar specimens were produced using two types of commercially-available reactive MgO as partial cement replacement (10%, 15% and 20%, by weight) and fine recycled concrete aggregate as siliceous sand substitute (50% and 100%, by volume). The specimens were subjected to thermogravimetric, energy dispersive X-ray, differential thermal and powder X-ray diffraction analyses. The mechanical and durability performance of all specimens was evaluated in terms of their flexural and compressive strength, dynamic modulus of elasticity, water absorption by capillary action, carbonation, and shrinkage. The main results indicate an overall decline in mechanical and durability-related performance with the use of both MgO and fine recycled concrete aggregates, but enhanced shrinkage behaviour was observed in all MgO-containing specimens.

TL;DR: In this article, the macroscopic and microscopic analyses on the mechanical performance of metakaolin (MK)/fly ash (FA) based geopolymer mortar were carried out through compression tests, bending tests, and phase analysis, to illustrate the mechanisms of the interaction between fiber and nano additives.

TL;DR: In this paper, the authors proposed a 2D mesoscale model in which the concrete is modeled as a heterogeneous three-phase material composed of coarse aggregates, mortar matrix and Interfacial Transition Zone (ITZ).

TL;DR: In this article, the effect of fly ash fineness and replacement ratio on properties of blended cement mortar was investigated and the results showed that the use of fly ashes resulted in significant improvement in compressive strength and substantial decrease in water absorption and capillary pores for blended cement mortars compared to OPC mortar.

TL;DR: In this article, the early-age hydration characteristics of composite binder containing iron tailing powder were investigated by determining the hydration heat, non-evaporable water content, pore structure, and morphology of hardened paste as well as the compressive strength of mortar.
