Abstract: This paper takes the secondary grouting of equipment foundation in a chemical silane gas area as an example, BASF epoxy grouting material is used, pouring construction shall be carried out after mixing in proportion on site, engineering practice has proved that it has the characteristics of early strength, high tensile strength, high compression resistance, high fluidity and high strength and micro expansion under high temperature. The scheme used in this paper is based on the actual situation, it is formulated in combination with the construction method issued by the manufacturer, practice has proved that all the indexes are in line with the relevant provisions in the specification.
