New Mortar Mixes with Chemically Depolymerized Waste PET Aggregates
Dora Foti,Michela Lerna +1 more
TL;DR: In this paper, recycled PET (polyethylene terephthalate) nanoparticles were used as a substitute for sand in mortars and the results of the mechanical tests showed a reduction of the flexural and compressive strength values when the amount of PET nanoparticles increase.
Mechanical Characteristics and Water Absorption Properties of Blast-Furnace Slag Concretes with Fly Ashes or Microsilica Additions
TL;DR: In this paper, the results of an experimental tests campaign carried out on concretes with recycled aggregates added in substitution of sand were presented, and the results showed that in the concrete so made the water absorption capacity has reduced and durability has improved, which can be especially utilized for research on a larger scale in this field.

Effect of the Chemical and Mechanical Recycling of PET on the Thermal and Mechanical Response of Mortars and Premixed Screeds
TL;DR: In this paper , the effect of recycling polyethylene terephthalate (PET) on the thermal performance of building materials has been evaluated, and the results of the experimental campaign have made it possible to evaluate the influence of the recycled material on the physical and mechanical properties and its feasibility in non-structural applications.
Experimental Characterization of Traditional Mortars and Polyurethane Foams in Masonry Wall
TL;DR: In this article, the behavior of polyurethane foams, used as adhesives for the construction of thin joints brick masonry walls, has been investigated and compared with traditional mortars masonry, as the type of joints varies and the arrangement of the holes of the bricks varies with respect to the direction of the applied load.
