High Intensity and Non- Shrink Cementitious Grout
Type:DMARGrout-618
Description: DMARGrout-618 is a cement based grout composed of sand, concrete additives and other materials. It can be used after adding some water and mixing around. It represents performance like flowable, tiny expansion, non-isolation and high strength etc.
Uses: DMARGrout-618 is suitable for the following grouting works:
1.The secondary grouting between ground bolt and machine base of large-scale equipments and precise equipments.
2.The secondary grouting of joint between steel structure and concrete.
3.Anchor the steel bar.
4.Filling and fixing of the contrary-striking constitution joints of the underground works.
5.The secondary reinforcement of girder and column.
6.Rush repair the part of roads.
