In spite of not being legally accepted in most countries, mixed recycled aggregates (MRA) could be a suitable raw material for concrete manufacturing. The aims of this research were as follows: (i) to analyze the effect of the replacement ratio of natural coarse aggregates with MRA, the amount of ceramic particles in MRA, and the amount of cement, on the mechanical and physical properties of a ...

The construction sector is one of the main consumers raw materials and generates a high volume waste within European Union. search for new that are more sustainable respectful environment has become challenge countries with degree industrialization. In this work, study most relevant properties masonry mortars made recycled aggregates reinforced synthetic fibers was carried out. Three types were...

The construction and demolition waste can be used as an alternative with a lower environmental impact compared to the use of natural aggregates in concrete mortar manufacture. In this work, it has been performed analysis lime cement properties made ceramic recycled reinforced three types fibers: glass, basalt carbon. An experimental campaign carried out which includes chemical physical characte...

This paper presents a recycled aggregate concrete (RAC) mix that has been modified by adding treated recycled concrete aggregate (RCA) and various types of fiber-reinforced systems. The effectiveness of these modifications in terms of energy absorption and impact resistance was evaluated and compared with that of the corresponding regular concrete, as well as with unmodified RAC specimens. Resu...

Material adsorption, the reverse process of evaporation diffusion, directly reflects the wettability of materials. Wettability is one of the main factors that affect the drying shrinkage of materials. A device that measures the wettability of recycled aggregate concrete (RAC) with fly ash is proposed in this study based on pore structure theory. The isothermal absorption curve of RAC is examine...

The construction industry consumes many natural resources and generates a large amount of waste in the environment, all phases life cycle. For this reason, use recycled material is increasingly being encouraged, instead original raw for production new materials that contribute to closing cycle.
 objective study was evaluate compare environmental impacts obtaining aggregate aggregate, takin...
