Optimización de la resistencia a compresión usando un diseño de mezcla de vértices extremos, en concretos ternarios basados en residuo de mampostería y cal hidratada
(Universidad EIA, Envigado, Colombia, 2019)
The search for alternative materials that partially substitute Portland cement is important because of the environmental problems that this presents in its production, hence the need to investigate the use of ternary ...
Valorización y optimización del residuo de mampostería para la elaboración de concreto autocompactante
(Universidad Nacional de Colombia. Sede Medellín. Facultad de Minas, 2019)
The use of different supplementary cementitious materials (SCM) in the production of self-compacting concretes (SCCs) is an increasingly common practice. In this paper, results of a research about the use of residue of ...
Distribución espacio-temporal de Diatraea spp. (Lepidoptera: Crambidae) en el valle del río Cauca, Colombia
(Sociedad Colombiana de Entomología, SOCOLEN, 2018)
Sugarcane stem borer (Diatraea spp.) damage has increased in the Cauca River Valley (CRV) due to two new species, D. tabernella and D. busckella, which joined the two already known species, D. saccharalis and D. indigenella. ...
Geopolymeric concretes based on fly ash with high unburned content
(Elsevier, 2018-03-20)
This study used fly ash (FA) with a high amount of unburned content (21%) to produce simple (Geo FA) and binary (Geo FA/granulated blast furnace slag [GBFS]) geopolymeric concretes. The effect on the mechanical strength ...
Modelación del módulo de la resistencia a la flexión de un material compuesto cementicio a partir de propiedades en estado fresco
(Scielo, 2014)
In this research we studied the relationship between fresh state and hardened state of a fiber reinforced laminate compound (MCLRF), respectively, based on a matrix of Portland cement. The variables that have been worked ...
Optimización de la resistencia mecánica de cementos binarios MK/GBFS activados alcalinamente por Metodología de Superficie de Respuesta
(Universidad EAFIT, 201401)
The present article shows the compressive strength modeling and optimization for a non-conventional binder free of clinker, which was produced by the alkali activation of a binary mixture of metakaolin (MK) and a granulated ...
Optimization of physical, optical and barrier properties of films made from cassava starch and rosemary oil
(Springer Nature, 2018-11-07)
In this study, films from cassava starch and rosemary oil were prepared by using the casting method. Glycerol was used as plasticizer and tween 80 as surfactant. The influence of Cassava starch (Cs), Rosemary oil (Ro), ...
Evaluación de la corrosión del acero embebido en concreto AAS, expuesto a carbonatación mediante un experimento factorial con medidas repetidas
(Universidad Eafit, 2013-01)
En este artículo se presentan las técnicas de evaluación de la corrosión, tales como potencial de corrosión, resistencia lineal a la polarización y pulso galvanostático a los concretos de activación alcalina (AAS) y Portland ...
Reusing a residue of the oil industry (FCC) in the production of building elementsReutilización de un residuo de la industria petrolera (FCC) en la producción de elementos constructivos
(Universidad Javeriana, 2015-01)
Este trabajo analiza la viabilidad de utilizar un residuo de catalizador gastado (FCC) del proceso de craqueo catalítico, procedente de una empresa petrolera colombiana, en la producción de elementos constructivos, tipo ...
Optimization of the technological properties of porcelain tile bodies containing rice straw ash using the design of experiments methodology
(Elsevier Ltd, 2016-06-28)
This study examines the effects of replacing fluxing and filler materials with rice straw ash (RSA) in manufacturing porcelain stoneware tile, using the design of experiments (DOE) methodology. The results of the ...
