Potenciando el desarrollo local de comunidades afectadas por desastres
submitted by kudrws 1 hour ago - Topic: Architecture
En este artículo formularemos un análisis conceptual para proponer que los desastres usualmente conocidos como “naturales” son fenómenos sociales. Revisaremos cada fase de un desastre para descubrir las relaciones sociales que allí se generan y nos permiten fundamentar esta forma de compr...

El proceso de reconstrucción de viviendas en el centro de Talca: fotografía a dos años de la catástrofe
submitted by kudrws 1 hour ago - Topic: Architecture
Talca fue una de las ciudades con mayor daño en vivienda después del terremoto del 27F. Su casco histórico y 15 barrios fundacionales en torno a él, quedaron con la mayor parte de sus viviendas dañadas o destruidas. A dos años de ocurrido el terremoto, gran parte de la destrucción ocasiona...

New insights into water bonding during early tricalcium silicate hydration with quasielastic neutron scattering
submitted by buttram 6 hours ago - Topic: Architecture
New information on the water bonding during the first 36h of hydration of tricalcium silicate was obtained using the high neutron flux at the sample position of the time-of-flight spectrometer (TOFTOF), FRM II in Garching, Germany, together with 29Si NMR and X-ray diffraction measurements. A rapi...

Service Life and Life Cycle Cost Modelling of Cathodic Protection Systems for Concrete Structures
submitted by curran 6 hours ago - Topic: Architecture
Cathodic protection (CP) of reinforcing steel has been applied successfully to concrete structures with corrosion damage for more than 25 years. Performance and maintenance data are reported from an inventory of CP systems in The Netherlands installed on about 100 structures between 1987 and 2010...

Engineering properties of controlled low-strength materials containing waste oyster shells
submitted by brokynrf 13 hours ago - Topic: Architecture
To evaluate the practical application of waste oyster shells (WOS) as controlled low-strength materials (CLSM), using a reference sample and four fine aggregate replacement 5%, 10%, 15% and 20% WOS sand, and the cement was replaced by 20% fly ash of the materials were tested. The hardened propert...

Utilization of andesite processing wastewater treatment sludge as admixture in concrete mix
submitted by brokynrf 13 hours ago - Topic: Architecture
The dried physicochemical sludge from the coagulation–flocculation treatment of an andesite processing plant wastewater was used as concrete admixture in powder form. Various physicochemical sludges obtained with various coagulant/flocculants (alum, FeCl3, and sepiolite) were experienced dry pa...

Durability of expanded polystyrene mortars
submitted by brokynrf 13 hours ago - Topic: Architecture
The influence of the addition of various types and various concentrations of expanded polystyrene foam (both commercial and recycled) on the durability of Portland cement mortars is studied. In particular, the microstructure is studied utilizing the following methods: capillary absorption of wate...

Lattice Modeling of Chloride Diffusion in Sound and Cracked Concrete
submitted by curran 13 hours ago - Topic: Architecture
Reinforced concrete structures are frequently exposed to aggressive environmental conditions. Most notably, chloride ions from sea water or de-icing salts are potentially harmful since they promote corrosion of steel reinforcement. Concrete cover of sufficient quality and depth can ensure protect...

Effects of humidity, temperature and slow oxidation reactions on the occurrence of gasoline-air explosions
submitted by vandor2001 19 hours ago - Topic: Architecture
In order to investigate the effects of the humidity, temperature and slow oxidation reactions on the occurrence of explosions in gasoline-air mixtures, experiments are carried out in a cylindrical tunnel with a solid heating device. Experimental results show that whether a gasoline-air explosion ...

Housing and health in an informal settlement upgrade in Cape Town, South Africa
submitted by ellistlsll 20 hours ago - Topic: Architecture
Taking a socio-ecological perspective the World Health Organisation recognizes that housing comprises four interrelated dimensions—the physical structure of the house, the home, the neighbourhood infrastructure and the community. Housing related health vulnerability arises when residents are ex...

SOFIE project – 3D shaking table test on a seven-storey full-scale cross-laminated building
submitted by villena 1 day ago - Topic: Architecture
Multi-storey buildings made of cross-laminated timber panels (X-lam) are becoming a stronger and economically valid alternative in Europe compared with traditional masonry or concrete buildings. During the design process of these multi-storey buildings, also their earthquake behaviour has to be a...

Blind modal identification of output-only structures in time-domain based on complexity pursuit
submitted by villena 1 day ago - Topic: Architecture
Output-only modal identification is needed when only structural responses are available. As a powerful unsupervised learning algorithm, blind source separation (BSS) technique is able to recover the hidden sources and the unknown mixing process using only the observed mixtures. This paper propose...
