3. PHYSICAL, MECHANICAL AND THERMAL BEHAVIOUR OF ADOBE STABILIZED WITH THE SLUDGE OF WASTEWATER TREATMENT PLANTS
ABSTRACT The need for treated water is essential for life. With the constant increase in population, the most common way to purify surface water is through conventional water treatment plants (WTPs). The high volume of residue (sludge) generated in this process is most often returned to the catchment site, negatively affecting the ecosystem. The sludge of WT

5. Urbanización de viviendas y gestión ecoeficiente de residuos de construcción en Chile: aplicación del modelo español
Abstract This paper summarises a pioneering experience in construction and demolition waste management (C&DW) in Chile. The case study consists of the construction of 17 detached dwellings that are part of an urbanisation project in the city of Temuco, in the Araucana region. The methodology developed in Spain for the C&DW quantification is employed for the

6. Analysis of generation and characterization of construction and demolition waste on construction sites in the city of Recife, Brazil
ABSTRACT In order to planning the Construction and Demolition Waste (CDW) management approach on a construction site, it is necessary to have a prior knowledge of what is being generated (qualitative analysis), the quantity that is being generated (quantitative analysis), and what is the proper final destination assigned to this material. This article propos

7. New azhdarchoid pterosaur (Pterosauria, Pterodactyloidea) with an unusual lower jaw from the Portezuelo Formation (Upper Cretaceous), Neuquén Group, Patagonia, Argentina
ABSTRACT A new azhdarchoid pterosaur from the Upper Cretaceous of Patagonia is described. The material consists of an incomplete edentulous lower jaw that was collected from the upper portion of the Portezuelo Formation (Turonian-Early Coniacian) at the Futalognko site, northwest of Neuquén city, Argentina. The overall morphology of Argentinadraco barrealen

9. EVALUATION OF POTENTIAL METHANE GENERATION IN THE INVESTIGATION OF AN ABANDONED CONTAMINATED LANDFILL IN SANTIAGO, CHILE
Abstract This study presents the environmental evaluation of an abandoned and potentially contaminated landfill using analyses for the presence of heavy metals and for methane generation potential. The site is located in the city of Santiago, Chile, and was used as a rural landfill for domestic, industrial and construction waste until 1978, but is now in a h

10. Mechanical Characterization of Synthetic Macrofibres
The present study proposes a methodology to characterize the mechanical properties of synthetic macrofibres, which are used as a reinforcement of new composites applied in civil construction industry. Some standards suggest that this characterization should be performed on original filaments and others propose using the current methodology used to characteri

11. Impact of vibrations on the final characteristics of normal and self-compacting concrete
The quality and durability of normal concrete directly depends on the number and the shape of voids, so, in order to produce durable concrete, it is necessary to reduce the amount of air that is trapped inside the concrete, which is usually done by vibrating the concrete in the mixing stage or the casting stage. Self-compacting concretes are concretes that,

12. Construction of nonreciprocal fuzzy preference relations with the use of preference functions
In order to model the preferences of a decision-maker (DM) by means of fuzzy preferencerelations, a DM can utilize different preference formats (such as ordering of the alternatives, utility values, multiplicative preference relations, fuzzy estimates, and reciprocal as well as nonreciprocal fuzzy preference relations) to express his/her judgments. Afterward
