Mechanical properties and microstructure of cement multicomponent systems containing pozzolan materials under sulfate attack
(STOWARZYSZENIE PRODUCENTOW CEMENTU, 2020)
Sulfates are a significant chemical components that may lead to failures of cement concrete composites. The present study is dedicated to analyzing the effects of sulfate on the microstructure of cement composite mortars. ...
A study on ASR mitigation by optimized particle size distribution
(ELSEVIER SCI LTD, 2020)
In this study, the effect of alkali-silica reaction on binary cementitious composite systems incorporating fly ash or slag having optimized particle size distribution has been investigated. Specimens have been exposed to ...
Optimizing of phase plan, sequence and signal timing based on flower pollination algorithm for signalized intersections
(SPRINGER, 2020)
The purpose of this study is to develop a control system that optimizes the phase plan, sequence and signal timing using the flower pollination algorithm (FPA). At the same time, it is aimed to improve the fixed-time control ...
Gamma ray and neutron shielding characteristics of polypropylene fiber-reinforced heavyweight concrete exposed to high temperatures
(ELSEVIER SCI LTD, 2020)
The residual properties of shielding structures need to be redefined after exposure to elevated temperatures due to their probable radiological hazards on biodiversity. In this study, the effect of high temperatures on ...
Enhancement on mechanical and durability performances of binary cementitious systems by optimizing particle size distribution of fly ash
(SPRINGERNATURE, 2020)
Fly ash is a well-known supplementary cementitious material that is the by-product of coal-fired thermal power plants. The contribution of fly ash to the enhancement of the mechanical and durability properties of cementitious ...
Analysis of the relationship between LSTM network traffic flow prediction performance and statistical characteristics of standard and nonstandard data
(WILEY, 2020)
The effectiveness of road traffic control systems can be increased with the help of a model that can accurately predict short-term traffic flow. Therefore, the performance of the preferred approach to develop a prediction ...
Comparison of artificial bee colony and flower pollination algorithms in vehicle delay models at signalized intersections
(SPRINGER LONDON LTD, 2020)
Delay is a significant research topic since it includes indicators such as travel quality, lost time and fuel consumption. Furthermore, the delay is used for optimization of traffic control systems and determination of the ...
Investigation on variables affecting bond strength between FRP reinforcing bar and concrete by modified hinged beam tests
(ELSEVIER SCI LTD, 2020)
Abstract
The bond strength between FRP reinforcement and concrete significantly affects the load bearing capacity and deformation ability of an FRP reinforced concrete member subjected to bending. There are numerous ...
Engineering plastic gripping mechanism for tension testing of FRP bars
(SAGE PUBLICATIONS LTD, 2020)
A new grip adaptor, made of an engineering plastic Cast Polyamide 6 (PA6G), was developed for tension testing of FRP reinforcing bars. The new adaptor offers several advantages over conventional anchors, including the ease ...
Behavior and strength of hidden Rc beams embedded in slabs
(ELSEVIER, 2020)
Reinforced concrete (RC) beams protrude from the ceiling, unless there is an infill wall beneath. Sometimes the construction of these beams is avoided due to aesthetic concerns, and instead a reinforcement arrangement with ...
