Grout

1. Excellent Workability
UGM paste possesses superfluity at very low w/s and can fill any designated space completely.

2. Non-shrinking
Because UGM posses small expansive function, foundation bolt and pedestal of facilities can be combined with concrete foundation steadily.

3. Non-bleeing
UGM paste shows no signs of bleeding and settlement; thus poor conjunction can be avoided.

4. Higher early and final strength
At the age of 1 day, compressive strength value is more than 20 MPa ;at the age of 28 days, compressive value is more than 80 MPa.Therefore facilities can be installed with in 1-3days.

5. Higher bond strength Hardened UGM body posses stable expansive stress, thus bond stress of UGM body to foundation bolt is large; an bond of UGM body to old concrete is strong.

6. Superior durability UGM is inorganic grout material, hardened UGM body shows no signs of aging, and possesses superior resistance to the corrosion of reinforcement.

II Application

1. Pouring secondly foundation bolt of large-scale facilities or maternity base.

2. Pouring facilities and structural steel-concrete anchoring. Pouring preformed cavity that is available of stretching post-tensioned prestressed wire.

3. Pouring structures working joint.

4. Strength secondary beam and pillar.

5. Making self-leveling materials.

III Technical Properties

1.Setting time: initial set≥2 hours, final set≤10 hours.

2.Non-bleeding

3.Fluidity:more than　?250 mm

4.Compressive strength: 1 day≥20Mpa, 3 day≥30Mpa 7 days≥50Mpa, 28 days≥70Mpa.

5.Free expansive ratio >0.2%

6.Bond strength: 28days≥6Mpa.

IV Instruction to use

1 .At pouring small-area space, UGM can be mixed with water directly. It's mixture ratio is UGM :water=1:0.13-0.15 (13%～15%)

2.At pouring large space, put some pea grovels into UGM firstly (UGM: pea gravels=2:1),then mix the compound with water. The compressive strength and expansive ration can not be altered when pea graves is put into UGM.

3. At pouring hole or small-area space, adopt penetrative manner by labor to density UGM mortar. Finishing and compassing must be done as soon as exposed surface is digraph.

4. After reaching final setting time, hardened spraying water or covering wet sack must cure UGM body. The curving time is 7-14 days.
