Prediction of concrete strength using ultrasonic pulse velocity and artificial neural networks
Gregor Trtnik, Franci Kavčič, Goran Turk
Izvirni znanstveni članek
Oznake: hitrost ultrazvoka;svež beton;tlačna trdnost;umetna nevroska mreža;ultrasonic pulse velocity;young cobcrete;compressive strenght;artfical neural network;
Ultrasonic pulse velocity technique is one of the most popular non-destructive techniques used in the assessment of concrete properties. However, it is very difficult to accurately evaluate the concrete compressive strength with this method since the ultrasonic pulse velocity values are affected by ...

ǂThe ǂuse of artificial neural networks in adiabatic curves modeling
Gregor Trtnik, Franci Kavčič, Goran Turk
Izvirni znanstveni članek
Oznake: sveži beton;adiabatne krivulje;hidratacije betona;eksperimenti;umetne nevronske mreže;
Adiabatic hydration curves are the most suitable data for temperature calculations in concrete hardening structures. However, it is very difficult to predict the adiabatic hydration curve of an arbitrary concrete mixture. The idea of modeling adiabatic temperature rise during concrete hydration with ...

Comparison between two ultrasonic methods in their ability to monitor the setting process of cement pastes
Gregor Trtnik, Marko Valič, Franci Kavčič, Goran Turk
Izvirni znanstveni članek
Oznake: hidratacija;cementna pasta;ultrazvočni valovi;vezanje;prehod;odboj;hydration;cement paste;ultrasonic wave transmition;ultrasonic wave reflection;setting;
This paper presents the comparison between ultrasonic wave transmission (USWT) method and ultrasonic wave reflection (USWR) method in their ability to monitor the setting process of cement pastes. The velocity of ultrasonic longitudinal waves and shear wave reflection coefficient were measured simul ...

New numerical procedure for the prediction of temperature development in early age concrete structures
Anka Ilc, Goran Turk, Franci Kavčič, Gregor Trtnik
Izvirni znanstveni članek
Oznake: mladi beton;adiabatna kalorimetrija;adiabatne krivulje;umetne nevronske mreže;zrelost;metoda končnih elementov;young concrete;adiabatic calorimetry;adiabatic hydration curves;artificial neural networks;maturity;finite element method;
A new numerical model for the prediction of temperature development in young concrete structures is briefly presented. With the pre-program. adiabatic hydration curves, which are used to determine the internal heat generation, are calculated. An artificial neural networks approach is used for this p ...

Possibilities of using the ultrasonic wave transmission method to estimate initial setting time of cement paste
Gregor Trtnik, Goran Turk, Franci Kavčič, Violeta Bokan-Bosiljkov
Izvirni znanstveni članek
Oznake: hidratacija;cementna pasta;prehod ultrazvočnih valov;začetni čas vezanja;hidration;cement paste;ultrasonic wave transmition;initial setting time;
In this paper, the applicability of the ultrasonic wave transmission method to estimate the initial setting time of an arbitrary cement paste is discussed. Ultrasonic pulse velocity measurements were fully automated and measured continuously. The Vicar Needle Test was used in order to determine the ...
