Nedeljković, Marija (author), Arbi, Kamel (author), Ye, Guang (author)The reduction of pH from ~12.5 to ~9 by carbonation of the pore solution of reinforced cementbased concrete structures results in the reinforcement corrosion. The rate of carbonation is an important input for design of the concrete cover depth and the service life prediction of reinforced concrete structures because the initiation of...conference paper 2021

(author), Zuo, Y. (author)The aim of RILEM TC 247-DTA ‘Durability Testing of Alkali-Activated Materials’ is to identify and validate methodologies for testing the durability of alkali-activated concretes. To underpin the durability testing work of this committee, five alkali-activated concrete mixes were developed based on blast furnace slag, fly ash, and flash-calcined...journal article 2019

Nedeljković, Marija (author), Zuo, Y. (author), Arbi, Kamel (author), Ye, G. (author)In this paper, carbonation resistance of alkali-activated slag (AAS) pastes exposed to natural and accelerated conditions up to 1 year was investigated. Two aspects of carbonation mechanism were evaluated. The first was the potential carbonation of the main binding phases in finely powdered AAS pastes. The second was the reactivity and...journal article 2018

Arbi, K.A. (author), Nedeljkovic, M. (author), Zuo, Y. (author), Grunewald, S. (author), Keulen, A. (author), Ye, G. (author)This paper presents an investigation on workability and strength of geopolymer concrete made of fly ash (FA), blast furnace slag (BFS) and a multicompound activator of Na2SiO3 and NaOH solutions. The FA/BFS ratios were 100:0, 70:30, 60:40, 50:50, 40:60, 30:70 and 0:100. The workability of geopolymer concretes was performed by using slump test...conference paper 2015
