The site configuration epoxy grout matters needing attention

Due to the construction site sand quality change is opposite bigger, so the site construction personnel must guarantee the quality of sand and gravel requirement, adjust water-cement ratio and sand moisture content according to the site, to ensure that the epoxy grout mixture ratio, cannot confuse laboratory than ratio and construction. At the same time, the quality of epoxy grout and the kinds of additive, the relationship between mixing amount, adding way, it is also one of the important factors influencing the strength of epoxy grout. Epoxy grout strength only under the condition of temperature and humidity for can guarantee the normal development, should according to the norms of construction shall be maintained. The temperature high and low strength of epoxy grout has certain influence. Should put the summer sun, make full use of high and low temperatures in the morning and at night time pouring epoxy grout, because epoxy grout surface during drying temperature, when the water cooling, the heating effect will reduce epoxy grout strength and crack resistance. To insulation against the cold winter, the winter construction generally adopt comprehensive heat and steam curing epoxy grout as chemical admixture and the widespread use of superfine mineral admixture, our country existing reinforced epoxy grout mixture ratio design specification already cannot satisfy the high performance epoxy grout configuration, and the construction of the practical need of.
