The durability of the interpretation of the epoxy grout

Durability of epoxy grout cut the dosage of the mixing water and gelling slurry will stir the largest water consumption as a manipulation of the durability of epoxy grout a symbol of quality request, than with the water/cement ratio is more appropriate. Because of relying on the water/cement ratio control cannot solve grouting guess too many slurry, which caused shortened and the negative effect of hydration heat addition. In high-performance grouting guess, cuts in plasma volume, increase aggregate proportion, and progress in epoxy grout infiltration resistance or resistance to chloride ion dispersion of the main technique. If the manipulation of the mixing water dosage, can together manipulation of the dosage of slurry ( The bone than) From several aspects, it is possible to the durability of the request. For low water-binder ratio of epoxy grout normally should not exceed 150 kg/m3. The water-binder ratio in 0. 42 epoxy grout, under water usually should be controlled under 170 kg/m3. Manipulation of the epoxy grout water alone can manipulate grouting guess gelling material dosage, conducive to drop the permeability of epoxy grout, and cut short the amount, so it is necessary to have the highest consumption constraints. China about low water-binder ratio of epoxy grout gelling material dosage, bag yesterday has always been on the high side, even more than 550 kg/m3, the main reason is due to the aggregate of owe good quality, so it is necessary to notice the epoxy grout aggregate gradation and aggregate grain shape of the request
