TL;DR: In this paper, a conventional mortar was compared with ones incorporating rubber tyre particles, partly replacing the natural sand aggregates, and the compressive and tensile properties of these cement composites were investigated.

TL;DR: In this research, four types of waste seashells, including short-necked clam, green mussel, oyster, and cockle, were investigated experimentally to develop a cement product for masonry and plastering and indicate that ground Seashells can be applied as a cement replacement in mortar mixes and may improve the workability of rendering and plastered mortar.

TL;DR: In this paper, the effects of high temperatures up to 800°C on the mechanical properties and microstructure of nano-metakaolin cement mortars were investigated, and it was found that after an initial increase in compressive strength at 250°C for the mortar specimens, the strength decreased considerably at higher temperatures.

TL;DR: In this article, the influence of aggregate size and volume fraction on shrinkage induced micro-cracking and permeability of concrete and mortar was investigated, based on a 2D lattice approach in which aggregates were simplified as monosized cylindrical inclusions.
Abstract: In this paper, the influence of aggregate size and volume fraction on shrinkage induced micro-cracking and permeability of concrete and mortar was investigated. Nonlinear finite element analyses of model concrete and mortar specimens with regular and random aggregate arrangements were performed. The aggregate diameter was varied between 2 and 16 mm. Furthermore, a range of volume fractions between 0.1 and 0.5 was studied. The nonlinear analyses were based on a 2D lattice approach in which aggregates were simplified as monosized cylindrical inclusions. The analysis results were interpreted by means of crack length, crack width and change of permeability. The results show that increasing aggregate diameter (at equal volume fraction) and decreasing volume fraction (at equal aggregate diameter), increases crack width and consequently greatly increases permeability.

TL;DR: In this article, the possibility of recycling waste plastic (polyethylene terephthalate (PET) used for the bags manufacture) as a fine aggregate instead of sand in the manufacturing of the self-compacting mortars was investigated.
