High strength non-shrinkage grout is prepared with high strength material as aggregate, cement as binding agent, supplemented with high flow state, micro expansion and anti-separation substances. It can be used after adding a certain amount of water at the construction site and mixing evenly, mainly used for secondary grouting of equipment foundation, reinforcement of beams, plates and columns, and pavement repair works, etc.

Construction method.
1、 Prepare the mixer, grouting equipment, formwork and maintenance items, clean up the grouting space and wet the concrete surface in advance.
2、 Set up the formwork and seal the formwork joints with cement (mortar) and plastic tape to ensure no leakage of water and grout.
3、 Mix the grout with water according to 12-15% of grout weight (2-3 minutes for mechanical mixing, more than 5 minutes for manual mixing)
4、 Put the well-mixed grout into the grouting part from one direction. If necessary, it can be infused with the help of bamboo strips or steel brazier, and can be properly vibrated or gently tapped on the template.
5、 Immediately after construction, cover with plastic film and cover with grass curtain or quilt for 3-7 days for shade maintenance.
6、 The use temperature is -10℃ to 40℃. It is strictly forbidden to mix any admixture or external admixture in the grout.

Product features:
1. Early strength, high strength: 1-3 days compressive strength can reach more than 30-50Mpa.
2. High self-flowing: It can fill all the gaps and meet the requirements of secondary grouting of equipment.
3. Micro-expansion Close contact between equipment and foundation, no shrinkage after secondary grouting. High bond strength, grip force with round steel is not less than 6Mpa.
4. Can be constructed in winter: outdoor construction is allowed in -10℃ temperature.
5. Strong durability: This product is an inorganic cementing material, and its service life is greater than the service life of foundation concrete. It has been tested for millions of times by fatigue test and 50 times by freeze-thaw cycle without significant change in strength. After soaking in engine oil for 30 days, the strength is obviously improved.

Product use:
1.Suitable for grouting machine base, foot bolt and other equipment foundation.
2. Reinforcement, repair and strengthening of beams, slabs, columns, foundations, floors and roads of buildings.
3.It can be used for anchoring and structural reinforcement of footing bolts and steel bars.
4. The inlay of construction joints in subway, tunnel, underground and other projects with reverse punching method.
5. And the secondary grouting of steel structure (steel rail, steel frame, steel column, etc.) and foundation fixed connection.
