Mitigating alkali silica reaction in recycled concrete
… procedures of ASTM C 1260/1567 and ASTM C 1293. Pore solution analysis and Thermal Gravimetric Analysis (TGA) were also conducted.</p><p>It was found that fly ash, silica fume and ground granulated blast furnace slag (GGBFS) were effective in mitigating ASR in RCA concrete. Compared to …

Understanding the retardation of cement hydration caused by zinc
… mechanism behind the retardation and proposing solutions to mitigate it. This project was undertaken to develop a better understanding of the cement-zinc system and contribute to the narrow pool of research. The cement-zinc system was studied at very early ages (first 48 h) as it provided …

Understanding the role of slag on geopolymer hardening and microstructural development
… in the samples supporting the theory. The pore solution extracted from geopolymer at various time intervals was also characterized through inductively coupled plasma spectroscopy for various ions like silicon, aluminum and calcium. As variation in ion concentrations was too high between …

The Influence of Amorphous, Sub-Micrometer Silica Particles in Cement Pastes and Mortars with Very Low Water-to-Cement Ratios (Ultra-High Performance Concrete)
… silica enhances clinker hydration due to its dissolution and subsequent pozzolanic reaction to calcium–silicate–hydrate phases (C–S–H phases) and/or due to a heterogeneous nucleation of C–S–H phases from alite hydration on silica surfaces (seeding effect). Herein, the influence of the reactivity …
