The compound with epoxy grout conform to technical requirements?

In fact, in many of the actual don't need that high strength epoxy grout, it is ok to achieve C35, C40, for example, can completely meet the construction requirements. To general many of C30 concrete products, meet with C40 requirements, had to pay high price for strength to C55 grouting material. GB / T50448 - 2008 'cement grouting material application technical specifications' of the many indicators that are high in practice didn't make much sense. In some special applications, however, will need, such as wind power base, fluidity better in more than 340, the open time best more than 60 minutes, 65 mpa compressive strength can do it.
