Given that QS contains highly crystalized SiO 2 and various impurity silicate minerals and shows a solubility lower than quartz, a higher level of autoclave curing condition is required when adopting QS as a silica source. It is necessary to optimize the curing condition to the promotion of the tobermorite-generating hydrothermal reaction while ...

Full Description of Quartz Wool. The random asymmetric arrangement of fragile and flexible fibers of fused quartz is termed Quartz wool. It is also known as silica wool. It is a milky white color that looks like cotton wool. It is made up of highly pure SiO2 and high-quality quartz crystals. Like fused quartz products, it also has similar ...

Quartz sand should be characterized by a continuous grain size curve, without the dominance of any fraction. Proper graining of quartz sands used in the technology of sand-lime products is considered sand containing the following grain fractions: 2.5–0.5 mm in a proportion not exceeding 30%, and 0.5–0.05 mm in a proportion of at least 65%.

Replacing quartz powder with the coarser quartz aggregate in C mixture also increased the porosity after 1 MPa autoclave curing. This means quartz powder is also a silica source in autoclave curing and contributes to the formation of tobermorite structure. This finding explains the high mechanical performance of C mixture without SF.

However, the Ca/Si ratio of hydrates around quartz powder in steam and autoclave-cured specimens is much lower than hydrates far away from quartz powder and clinker [26]. This difference is attributed to the pozzolanic reaction between quartz powder and Ca(OH) 2, which increases the silicon content of hydrates. It should be noted that the ...
