The aim of the present work was to characterize products obtained from treatment phosphogypsum residue by means two recovery routes, and also evaluate concentrations heavy metals radionuclides in materials their leachates. In this way, it is possible determine how most hazardous components behave during procedures until stabilization through CO
The incorporation of crushed glass as a substitute for natural aggregates in mortar and concrete represents positive impact on the manufacturing processes. use residues can lead to improvement certain properties sustainable construction products. In these cases, it is important analyse detail behaviour material verify possible applications at an industrial level contribute development new products solutions. This work studies mortars with recycled partial replacement aggregate against common...
Since the Industrial Revolution, levels of CO2 in atmosphere have been constantly growing, producing an increase average global temperature. One options for Carbon Capture and Storage is mineral carbonation. The results this process fixing are safest long term, but main obstacle carbonation ability to do it economically terms both money energy cost. present study outlines a methodological sequence evaluate possibility ceramic construction waste (brick, concrete, tiles) under surface...
La incorporación a los conglomerados cementíceos de residuos construcción y/o demolición triturados tiene como objetivo conseguir un balance medioambiental positivo, manera que la industria asuma diverso origen. El vidrio residuo alto grado recuperación y numerosas posibilidades reutilización. morteros cemento se estudia con el fin conocer su comportamiento sustituto del árido capacidad modificar las propiedades producto final. presente trabajo aborda análisis modificaciones produce en...
Mineral carbonation of construction and demolition waste is a viable alternative for the reduction CO2 emissions from industry. Concrete cement, together with ceramic blocks, are primary sources calcium mineral in which fixed stable inert process. One type concrete was selected 5 tests. Crushed, separated into size fractions, moistened to 20% tested at 10 bars 24 720 h. Destruction portlandite ettringite phases determined. Calcite precipitated as carbonate phase. Maximum reached after 72 h,...
The goal of this research is to propose a new method characterizing rammed-earth walls. Based on their historic building materials properties, five broad test groups were established for the characterization: chemical and mineralogical composition, physical mechanical particle size distribution, dating. These determinations can, in turn, be grouped into two different types: instrumental techniques such as XRF, XRD, SEM-EDX, well adaptations standard methods (mainly UNE-EN standards)...
This study examines the perceived productivity of office occupants in moderate thermal environments Chile. Specifically, it analyses environmental parameters and contrasts participants' self-reported answers to cross-sectional retrospective questionnaires. To this end, data were collected for one day winter summer, eighteen buildings cities Concepción Santiago. The results show that average operative temperatures are 22.2 °C 23.5 summer. 80.5% declared their be normal on survey. However,...
This work addresses the reuse of waste products as a raw material for lime putties, which are one components mortar. 1:3 Lime/sand mortars very similar to conventional construction were prepared using putty obtained from treatment phosphogypsum with sodium hydroxide. The physical, rheological and mechanical properties this phosphogypsum-derived mortar have been studied, well mineralogical composition, microstructure by scanning electron microscope (SEM) curing process monitoring carbonation...
El objetivo del artículo es el estudio de viabilidad en mejoras eficiencia energética a través análisis ahorro energético y la inversión económica. Los resultados se han obtenido un modelo estudiado con distintas disposiciones, sistemas constructivos e intervenciones, incluyendo dos opciones rehabilitación respecto las transmitancias establecidas Apéndice D DB-HE Orden FOM/1635/2013, finalidad generar subcategorías edificios. ha basado demandas consumos obtenidos partir una herramienta...
In a previous study, layer of limewash was detected over the gypsum plasterworks used to decorate different spaces Real Alcázar Seville such as interior rooms, patios and outdoor galleries. this paper its use is analysed, namely whether it improves properties provides protective effect, through accelerated weathering tests designed specifically reproduce real environmental conditions. Plaster specimens with similar composition physical characteristics those original were prepared. After cure...
Energy efficiency in the residential sector is one of priorities European Union.It estimated to achieve an energy saving 27% group buildings EU countries by 2020 through directives issued Commission.The housing stock Spain are among least efficient Europe as a result, try introduce governmental aid encourage thermal refurbishment buildings.Currently programs rating focus on evaluation annual CO2 emissions, however indicators primary consumption or investment cost improvement measures not...
In recent years there has been renewed interest in innovative solutions for coating mortars. Previous research clarified the importance of substituting a percentage cement by other binders, and thus focused on good balance between structural thermal properties. However, effect economic cost carbon footprint is yet to be fully understood. this context, present study aimed at investigating role hydraulic lime as partial substitute expanded perlite properties mortars while considering...
This work presents a methodology for the assessment of ancient plasterworks based on traditional inspection techniques, such as organoleptic tests and chemical characterization, also digital tools, photogrammetric surveys, thermography images, measurement ambient conditions with thermohygrometers. method allows not only defining alterations detected establishing state conservation but digitalizing to preserve heritage replicate model if necessary (i.e., replacement detachment piece), drawing...
Abstract The construction of concrete structures for radiological protection in sanitary facilities requires a series constructive conditions that guarantee safety. influence the correct bunkers design, wall thicknesses and type materials used is essential to ensure effective protection. use barite aggregate common resource improve radiation attenuation capacity walls. present study analyses structure bunker during renovation work, studying characteristics chamber, state its elements,...
La producción industrial del ácido fosfórico presenta una gran demanda debido al uso cada vez mayor de fertilizantes, detergentes o productos limpieza. Este proceso genera año millones toneladas fosfoyesos como residuo. posibilidad incorporación este residuo en el desarrollo morteros tiene objetivo principal generar un impacto medioambiental positivo a partir reaprovechamiento material desecho materia prima para la obtención pasta cal. Adicionalmente, desarrollado cal implica captura CO2...
