查询词典 crystal particle

The image showed that the ratio of raw material of RPC and particle distribution accorded with maximum packing density theory, and the porosity of accumulation was the least. The DSC showed the reaction rate of RPC was very fast and main hydration process focused in shorter time; SEM and X-ray showed that structure of the harden body of RPC was much denser, which mainly composed of some abnormal flat grains that got maximum packing density, and hydration products were mostly composed of Ⅲ type C-SH gel and a small amount of Ca2 and no AFt crystal.
