RETRACTED: Durability Properties of High-Performance Concrete Incorporating Nano-TiO₂ and Fly Ash

The American Journal of Engineering and Applied Sciences has decided to retract the manuscript titled "Durability Properties of High-Performance Concrete Incorporating Nano-TiO₂ and Fly Ash" authored by Ehsan Mohseni, Malek Mohammad Ranjbar and Konstantinos Daniel Tsavdaridis, published in Volume 8, Issue 4 with the page numbering 519-526. After receiving a complaint, the editorial office found that the manuscript was translated from an article titled "Utilização de nano-partículas para a obtenção de betões de elevado desempenho" authored by a former Master Student, Eng Tiago Martins. The results are of his master thesis concluded in 2013 and were first presented in a conference that took place in Portugal on March of 2014. Therefore, on grounds of research misconduct the article in concern is being retracted.
