Evaluation of internal curing effects on concrete
(Universidad Nacional de Colombia, 2019)
The objective of the present research was the evaluation of some fresh and hardened-state properties of concretes, in which coarse aggregates were partially replaced by lightweight ones previously saturated, in percentages ...
Evaluación de la resistencia a compresión en morteros de cal, sometidos a diferentes condiciones de curado
(Escuela Colombiana de Ingeniería Julio Garavito, 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 ...
Assessment of Anchorage Methods and FRP Laminate Strengthening Configurations for URM Walls Under In-Plane Loading
(American Concrete Institute, 2018)
In order to ensure a continuous and reliable path for the lateral loads caused by earthquake or wind forces, FRP-strengthened masonry walls that are part of the lateral load resisting system of a building require the joint ...
Propiedades mecánicas, eléctricas y de durabilidad de concretos con agregados reciclados
(Escuela Colombiana de Ingeniería Julio Garavito, 2017)
The purpose of this article is to present the assessment of some of the electrical, mechanical and durability properties of concrete mixtures with replacement of coarse aggregate by aggregates of recycled concrete (ACR). ...
Machine Learning Prediction of Flexural Behavior of UHPFRC
(Springer Nature, 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 ...
Masonry Walls Reinforced with FRP Bars Subjected to Out-of-Plane Loading
(American Concrete Institute, 2018)
This article presents the results of a research program on the behavior of masonry walls reinforced with FRP bars subjected to out-of-plane loads. The article also proposes a preliminary protocol for the flexural design ...
Effect of FC3R on the properties of ultra-high-performance concrete with recycled glass
(Universidad Nacional de Colombia, 2019)
Ultra-high-performance concrete (UHPC) is the essential innovation in concrete research of the recent decades. However, because of the high contents of cement and silica fume used, the cost and environmental impact of UHPC ...
Mechanical Performance of Concrete with Waste from Oil Industry
(ACI American Concrete Institute, 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 ...
Conceptos básicos y principales metodologías del diseño estructural para condiciones de incendio según normas internacionales, aplicadas al Reglamento Colombiano de Construcciones Sismorresistentes (NSR-10)
(Escuela Colombiana de Ingeniería Julio Garavito, 2018)
Entre los principales cambios que trajo la aplicación del reglamento NSR-10, se encuentra el incremento en la seguridad estructural que se les debe proporcionar a las edificaciones, la cual debería preverse desde el mismo ...
Permeation properties of Concrete Added with a Petrochemical Industry Waste
(Universidad Nacional de Colombia, 2017)
The aim of this study is to evaluate the permeation properties of concrete added with a residue of a petrochemical industry located in Colombia, called catalytic cracking catalyst residue (FCC). Concrete samples with 10, ...
