The main colors of Ewende micro silica powders are off-white, grey and dark grey.
There is generally little difference in performance between different colors of micro silica powders. The performance of micro silica powder mainly depends on its chemical composition, fineness, specific surface area and other factors, rather than its color.
However, if the color of micro silica powder is abnormal, it may mean that it contains impurities or there are problems in the production process, which may have some impact on the performance. For example, a dark color may indicate the presence of too much carbon or other impurities, which may affect its enhancement and durability in concrete.
Overall, the performance of micro silica powder cannot be judged solely on the basis of its color, and a number of factors need to be considered comprehensively.
