Assessment of a mortar with recycled aggregate from a concrete improved by carbonation: a look to a sustainable construction
(Pontificia Universidad Católica de Chile.Santiago, Chile., 2019)In this article, some of the physical, mechanical, and durability properties of mortars were evaluated. These mortars had partial replacements of the natural fine aggregate (NFA) with recycled fine aggregate (RFA) and ... -
Development of cost-efficient UHPC with local materials in Colombia
(Books on DemandAlemania, 2020)Ultra-high-performance concrete (UHPC) is an essential innovation in concrete research of recent decades. However, because of the high contents of cement and silica fume used, the cost and environmental impact of UHPC is ... -
Evaluación de la metodología de ensayo acelerado de barras de mortero ASTM C 1260 para detectar agregados potencialmente reactivos y las medidas de mitigación de la reacción álcali-sílice ASTM C 1567
(Escuela Colombiana de Ingeniería Julio Garavito, 2018)The alkali-silica reaction is defined as a phenomenon produced by the alkalis (sodium or potassium) of the cement, which react with the silica present in certain aggregates, forming a gel that under conditions of humidity ... -
Evaluación de la metodología de ensayo acelerado de barras de mortero ASTM C 1260 para detectar agregados potencialmente reactivos y las medidas de mitigación de la reacción álcali-sílice ASTM C 1567
(Escuela Colombiana de Ingeniería Julio GaravitoMaestría en Ingeniería Civil con Énfasis en Estructuras, 2017)La reacción álcali sílice se define como un fenómeno producido por los álcalis (sodio o potasio) del cemento, los cuales reaccionan con la sílice presente en ciertos agregados, formando un gel que bajo condiciones de humedad ... -
Evaluación de la resistencia a compresión en morteros de cal, sometidos a diferentes condiciones de curado
(Escuela Colombiana de Ingeniería Julio GaravitoBogotá, Colombia., 2019)En este artículo se presenta la evaluación de la resistencia a compresión en morteros de cal, sometidos a diferentes condiciones de curado y diferentes edades de ensayo. En total, se evaluaron las propiedades ... -
Evaluación de parámetros de resistencia al corte en suelos de ladera cubiertos con vetiver
(Escuela Colombiana de Ingeniería Julio Garavito, 2017)The slopes are exposed to erosion and weathering processes that impose a loss of strength of the earth materials. Vetiver has the ability to retain soil particles with their tillers and to strengthen the soil with the ... -
External strengthening of unreinforced masonry walls with polymers reinforced with carbon fiber
(Universidad Nacional de ColombiaBogotá, Colombia., 2018)In many countries, buildings are usually made of unreinforced clay masonry walls, especially in Colombia. These constructions have low resistance and ductility, and are very vulnerable to seismic events, due to their low ... -
Influencia de la degradabilidad de las rocas en los parámetros de resistencia de los materiales de la formación Guaduas, al noroccidente de Bogotá
(Escuela Colombiana de Ingeniería Julio Garavito, 2017)El proceso de meteorización de las rocas genera cambios en sus características y propiedades, representados en una disminución de la resistencia del material. Las rocas de la formación Guaduas se encuentran constituidas ... -
Machine Learning Prediction of Flexural Behavior of UHPFRC
(Springer NatureSwitzerland, 2020)To evaluate the possibility of predicting the flexural behaviour of UHPFRC, four analytical models were developed, based on artificial neural networks (ANN), to predict the first cracking tension or Limit of Proportionality ... -
Mechanical Performance of Concrete with Waste from Oil Industry
(ACI American Concrete InstituteUnited State., 2016)In this paper, the mechanical properties of concrete with an added residue of the petrochemical industry (at levels of 10, 20, 30%), called catalytic cracking catalyst residue (FCC), are evaluated. The mechanical properties ... -
Natural hazards, vulnerability and structural resilience: tsunamis and industrial tanks
(Taylor and Francis Ltd.Reino Unido., 2016)The paper presents an integrated framework which deals with natural hazards (tsunamis), physical vulnerability modelling, risk of failure for industrial structures (metal structures) and structural resilience provided by ...
