Thomas Rougelot, Auteur ; Nicolas Burlion, Auteur ; Dominique Bernard, Auteur |Chemical shock of cement based materials leads to significant degradation of their physical properties. A typical scenario is a calcium leaching due to water (water with very low pH compared with that of pore fluid). The main objective of this p[...]

E. Mozaffari, Auteur ; J.M. Kinuthia, Auteur ; J. Bai Wild, Auteur |Wastepaper Sludge Ash (WSA) contains reactive components such as free lime (CaO), and less reactive and inert mineral species. When water is added to WSA some constituents hydrate faster than others, lime being the fastest giving high alkalinity[...]

Kolluru V. Subramaniam, Auteur ; Xiaojun Wang, Auteur |The response of hydrating cement paste through setting are monitored using rheological measurements and ultrasonic reflection measurements. Increases in the elastic modulus and yield stress of cement paste with time are obtained from the rheolog[...]

Analysis of carbonation behavior in concrete using neural network algorithm and carbonation modeling
Seung-Jun Kwon, Auteur ; Ha-Won Song, Auteur |Carbonation on concrete structures in underground sites or metropolitan cities is one of the major causes of steel corrosion in RC (Reinforced Concrete) structures. For quantitative evaluation of carbonation, physico-chemo modeling for reaction [...]

Ma. Guadalupe D. Gutiérrez-Padilla, Auteur ; Angela Bielefeldt, Auteur ; Serguei Ovtchinnikov, Auteur |Laboratory experiments were conducted to compare the degradation of low and high quality concrete under conditions simulating sewer pipes with and without bacteria. Small concrete samples were exposed to hydrogen sulfide, multiple species of bac[...]

J. Pourchez, Auteur ; P. Grosseau, Auteur ; B. Ruot, Auteur |The influence of cellulose ethers (CE) on C3S hydration processes was examined in order to improve our knowledge of the retarding effect of cellulose ethers on the cement hydration kinetics. In this frame, the impacts of various cellulose ethers[...]

F. Brunet, Auteur ; T. Charpentier, Auteur ; C. N. Chao, Auteur |The long term behaviour of cement based materials is strongly dependent on the paste microstructure and also on the internal chemistry. A CEM V blended cement containing pulverised fly ash (PFA) and blastfurnace slag (BFS) has been studied in or[...]

Gregor Trtnik, Auteur ; Marko Ivan Valič, Auteur ; Franci Kavčič, Auteur |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 an[...]

Ryan T. Chancey, Auteur ; Paul Stutzman, Auteur ; Maria C.G. Juenger, Auteur |A comprehensive approach to qualitative and quantitative characterization of crystalline and amorphous constituent phases of a largely heterogeneous Class F fly ash is presented. Traditionally, fly ash composition is expressed as bulk elemental [...]

Ueli Angst, Auteur ; Bernhard Elsenerb, Auteur ; Claus K. Larsena, Auteur |Chloride induced corrosion as the major cause for degradation of reinforced concrete has been the subject of great research efforts over the last fifty years. The present literature review summarises the state of the art by presenting the concep[...]
