Hydration reaction and compressive strength of small amount of silica fume on cement-fly ash matrix

open access: yesCase Studies in Construction Materials, 2022
In 2021, the price of silica fume had fallen to 400 RMB/ton in some areas, while that of cement had risen to 650 RMB/ton, which provided a realistic basis for applying silica fume in low- and medium-strength concrete. In this paper, the effects of adding

Comparison of Effect of Metakaolin and silica Fume on Fly Ash Concrete Performance

open access: yesMATEC Web of Conferences, 2016
Silica fume is a common mineral admixture used in HSC and HPC, but being its high price and shrinkage in concrete, its usage is under restrictions. As a new mineral admixture, metakaolin gets more and more attention.

Nanostructured Polymethylsiloxane/Fumed Silica Blends [PDF]

open access: yesMaterials, 2019
Polymethylsiloxane (PMS) and fumed silica, alone and in a blended form (1:1 w/w), differently pretreated, hydrated, and treated again, were studied using TEM and SEM, nitrogen adsorption–desorption, 1H MAS and 29Si CP/MAS NMR spectroscopy, infrared spectroscopy, and methods of quantum chemistry. Analysis of the effects of adding water (0–0.5 g of water
