In this paper, the effects of different aluminum to silicon ratios in silicate chains of calcium silicate hydrates (C-S-H) are evaluated on the diffusion coefficient of chloride ions by molecular dynamics method. Tobermorite is a crystalline phase that is used for studying C-S-H properties in nano scale, because of its analogous chemical composition to C-S-H. Aluminum incorporation in C-S-H and...

The adsorption capacity of cement hydrates considerably affects the ionic ingress into cementitious materials. In this study, surface electrostatic properties calcium silicate hydrate (C–S–H) and aluminosilicate (C-A-S-H) were determined to understand effects on chloride adsorption. density functional groups was by analysing structure C–S–H C-A-S-H through 27Al 29Si MAS NMR. sites ?SiOH ?AlOH a...

The nucleation of the C-S-H gel is a complex process, key to controlling hydration kinetics and microstructure development cement. In this paper, mechanism for crystallization step during non-classical proposed explored by atomistic simulation methods. portlandite precursor monolayers undergo chemically induced transformation condensation silicate dimmers, forming monolayers. We studied DFT nud...

in february and march 2005, the archaeological survey of righ saray desert in the northern part of varzaneh was conducted. ancient rigsray is an area which has been buried by the sandy dunes at the western margin of the marsh gavkhoni. during this project nearly 100 archaeological sites were identified and recorded. one of the most important sites identified by the survey is saba 9 which is the...

Most gorgonian octocoral species are described using diagnostic characteristics of their sclerites (microscopic skeletal components). Species in the genus Pterogorgia, however, are separated primarily by differences in their calyx and branch morphology. Specimens of a morphologically unusual Pterogorgia collected from Saba Bank in the NE Caribbean Sea were found with calyx morphology similar to...

BACKGROUND Recent trials have assessed the efficacy and safety of novel monoclonal antibodies such as reslizumab and benralizumab. However, the overall efficacy and safety anti-interleukin (IL) 5 treatment in asthma have not been thoroughly assessed. METHODS Randomized controlled trials (RCTs) of anti-IL-5 treatment on patients with asthma published up to October 2016 in PubMed, Embase, and C...
