reactions and surface interactions of saccharides in

2019-12-12 · Glucose, maltodextrin, and sucrose exhibit significant differences in their alkaline reaction properties and interactions in aluminate/silicate cement slurries that result in diverse hydration behaviors of cements. Using 1D solution- and solid-state 13C nuclear magnetic resonance (NMR), the structures of these closely related saccharides are identified in aqueous cement slurry solutions and as

2019-11-10 · This study investigated the effect of CaSO 4 on the hydration and phase conversion of CAC. The specimens were fabricated by incorporating 0, 2, 4, or 8% of CaSO 4 by the weight of cement. The specimens were exposed to 20 °C for 7 days initially and were then exposed at 60 °C to trigger the conversion of CAC

effect of addition of nano magnetite on the hydration

2012-9-27 · In this investigation the effect of addition of magnetite nanoparticles on the hydration characteristics of both ordinary Portland cement (OPC) and high slag cement (HSC) pastes was studied. The cement pastes were prepared using a water/solid (W/S) mass ratio of 0.3 with addition of 0.05, 0.1, and 0.3 % of magnetic fluid Fe3O4 nanoparticles by mass of cement. An aqueous stable magnetic …

geopolymers and fiber reinforced concrete composites in

This paper discusses the influence of fiber reinforcement on the properties of geopolymer concrete composites, based on fly ash, ground granulated blast furnace slag and metakaolin. Traditional concrete composites are brittle in nature due to low tensile strength. The inclusion of fibrous material alters brittle behavior of concrete along with a significant improvement in mechanical properties

The degree of hydration of cement and degree of reaction of silica fume are obtained as accompanied results from the proposed hydration model. The properties of hardening UHPC, such as degree of hydration of cement, calcium hydroxide contents, and compressive strength, are predicted from the contribution of cement hydration and pozzolanic reaction

2020-1-31 · To improve the utilization of crop straws as a resource and the compatibility between straw fibers and cement-based materials, the hydration of modified straw fiber cement-based composite (SFCC) was studied. The structural characteristic of SFCC was investigated by FTIR, SEM, and XRD. The results show that the setting time of several modified straw fiber SFCC pastes was shorter than …

pozzolanic effect of porcelain polishing residue in

2015-8-1 · Besides its filler effect (Wild et al., 1996, Pelisser et al., 2012), PPR can maximize hydration in Portland cement because it contains high amounts of amorphous silica and alumina, which promote the pozzolanic reaction (Mehta and Monteiro, 2006). During hydration, the residue can act as nucleation centers due to its small particle size after
