Development of cost-efficient UHPC with local materials in Colombia
(Books on Demand, 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 ...
Properties prediction of environmentally friendly ultra-highperformance concrete using artificial neural networks
(Taylor and Francis, 2020)
Ultra-high-performance concrete (UHPC) results from the mixture of several constituents, leading to a highly complex material in both, fresh and hardened state. The higher number of constituents, together with a higher ...
Factorial design of reactive concrete powder containing electric arc slag furnace and recycled glass powder
(Universidad Nacional de Colombia, 2020)
The main objective of this research is to develop an optimized mixture of reactive powder concrete (RPC) containing supplementary cementitious materials (SCM), such as Electric Arc Slag Furnace (EASF), and Recycled Glass ...
Comparative analysis of acoustic emissions produced in abrupt and non-abrupt fracture processes in reinforced concrete walls
(IOP Publishing Ltd, 2023)
The determination of the eventual abrupt fracture of a reinforced concrete structure is of fundamental importance to estimate and mitigate the possible damages caused by its failure; of particular importance are shear-type ...
Comportamiento sísmico de edificaciones de tapia pisada reforzadas con marcos de madera y viga de coronación en concreto
(Editorial CSIC, 2020)
La construcción en tierra está presente en todo el mundo. Muchas de estas construcciones se encuentran en regiones sísmicas y tienen una vulnerabilidad alta. Con el fin de reducir esta vulnerabilidad se propone una estrategia ...
A minimal model to understand the discrepancies between acoustic and electromagnetic emissions in fracturing processes
(IOP Publishing Ltd, 2021)
Despite their common origin, experiments show that acoustic and electromagnetic emissions evolve in different ways during the fracture processes of brittle materials. It is common to find peaks of acoustic activity without ...
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 ...
Analysis of metakaolin as partial substitution of ordinary portland cement in reactive powder concrete
(ASTM International, 2020)
Over the last 20 years, remarkable advances have taken place in the research on reactive powder concrete (RPC). However, because of the high contents of cement and silica fume (SF) usually used in those types of concrete, ...
Statistical Optimization of Ultra-High-Performance Glass Concrete
(American Concrete Institute, 2020)
This paper presents the experimental results of research carried out
involving the compressive strength and slump flow of ultra-highperformance concrete (UHPC) made with cementitious blends of recycled glass flour, recycled ...
