چکیده مقاله:
By application of nano silica bits, can increase the level of density, that cause to increase of micro and nanostructure of density of composing structure of concrete and at the end, due to mechanic specifications. Adding nano silica bits to cement base materials, cause to chemical analysis control due to H-C-S (Calcium. Silicate. Hydrate), which are occurred in effect of calcium subsidence and cause to prevent of water prevalence in concrete, that each of these cases, increase consistency of concrete. This study considers the effect of nano silica on concrete and show that for producing concrete with high persistence, use of nano silica, because of creating positive co act between cement paste and its’ beams, in nano metric measures, nano bits, show chemical and physicians specific attributes in comparison with other dimensions. Even, studies like producing high persistency of concrete with high activity and persistence in unsuitable atmospheric qualifications, are the considering subject of scholars. The action, behavior and cement attitudes depends on nano structure of concrete and cement. So, study in this course, has so many importance. Nano materials in comparison with microscopic materials, have so many basic difference in attitudes and measures. The aim of studying materials in nano scale is gaining a new family of high action stuff.
