What are the strengths of high strength non shrinkage grout, and is the price the same?

Changzhou Chuangheng high-strength non-shrinkage grout, with or without shrinkage cement grout and epoxy resin grout, with a strength of 60--120MPa, is an ideal grout for the foundation reinforcement of heavy-duty and vibrating compressor equipment.

Summary. High-strength non-shrinkage grout has the following 4 strength grades:

1、cgm-1

General purpose ruggedized type. The thickness of the grout is 30mm

2、cgm-2

Rock reinforcement type. Early strength and high strength of grouting material plant: the compressive strength can reach more than 30-50MPa in 1-3 days.

High self-flowing: it can fill all the voids and meet the requirements of the secondary grouting of the equipment. Micro-expansion:

Ensure close contact between the equipment and the foundation, and there is no shrinkage after the second grouting process. The bond strength is high, and the grip and wrapping force with the steel bar is not less than 6MPa. Winter construction is available:

Outdoor construction is allowed in temperatures of -10. It contains 5 10mm large aggregate (aggregate), which is suitable for the secondary grouting of equipment foundation with a grouting layer thickness of δ 150mm and a grouting length of l<1000mm. Reinforcement of beams, slabs, columns, foundations and floors of buildings (repair thickness 60mm).

How many strength grades are there for high-strength non-shrinkage grout?

Hello, happy to answer your questions.

There are four levels of strength for high-strength non-shrinkage grout: 1. CGM-1 general reinforcement type. The thickness of the grout is 30mm

3. CGM-3 fine reinforcement type. Polymer mortar is a new type of building material that has emerged in engineering in recent years, which is made by mixing cementitious materials and organic polymers that can be dispersed in water. It is widely used by people.

Polymers: dispersible latex powders: acrylates, polyvinyl alcohol, styrene-acrylates, etc.

Talking about aggregate in detail, it is suitable for the thickness of the grouting layer 5mm

Concrete pavement, airport runway, etc. are quickly repaired, and water stop and leakage are quickly repaired.

Generally speaking, high-strength non-shrinkage grout can be divided into 4 strength grades, namely CGM-1 (general-purpose type), CGM-2 (beanstone type), CGM-3 (ultra-fine type) and CGM-4 (early high-strength type).

1、cgm-1

General purpose ruggedized type. Grouting thickness 30mm<δ<150mm equipment foundation secondary grouting , anchor bolt anchoring, buried steel bars, building beams, slabs, columns, foundations and floor reinforcement.

2、cgm-2

Rock reinforcement type. Contains 5 10mm large aggregate, suitable for the secondary grouting of equipment foundation with a grouting layer thickness of δ 150mm and a grouting length of l<1000mm. Reinforcement of beams, slabs, columns, foundations and floors of buildings (repair thickness 60mm).

3、cgm-3

Ultra-fine ruggedized type. Ultra-fine aggregate is suitable for secondary grouting of equipment foundation and steel structure column base plate with a thickness of 5mm <δ< 30mm. Concrete beams and columns are reinforced with grout for the gap between the angle steel and the concrete.

4、cgm-4

Super early strength reinforcement type. The strength reaches 15MPa in 2 hours, which is suitable for rapid repair of railway sleepers, cement concrete pavement, airport runway, etc., and rapid repair of water stop and leakage.

The above is for this problem, I hope it can help you.

There are 4 strength grades of high-strength non-shrinkage grout. They are CGM-1 (general-purpose type), CGM-2 (beanstone type), CGM-3 (ultra-fine type), and CGM-4 (early high-strength type). It is widely used in grouting of various beam prestressed pipelines and grouting of equipment foundations, anchors and other components, and can also be used for repairing defects such as nuclear power plant shell grouting, concrete looseness, cracks and holes.

It is mainly composed of cement, special admixtures, supplemented by a variety of mineral modified components and polymer materials. It has the characteristics of low water-glue ratio, high fluidity, zero water secretion, micro-expansion, and good durability.

Do you know what non-shrinkage grout is? This is a polymer building material that uses cement as a binder, this building material is a high fluid shape, it is a micro-expanded material, a certain amount of water can be added to the site, and after mixing, it can be used for 20 irrigation of the foundation, which is generally used to build beams. Most of the buildings will use non-shrinkage grout when they are watered for secondary irrigation or posture cracking, which can effectively avoid retraction.

One**. The ** of non-shrinkage grouting material is generally about 30 yuan per barrel, which is **** in the network.

Second, 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 voids and meet the requirements of the secondary grouting of the equipment.

3.Micro-expansion: ensure close contact between the equipment and the foundation, and there is no shrinkage after the second grouting. The bonding strength is high, and the grip and wrapping force with the round steel is not less than 6MPa.

4.Winter construction possible: Outdoor construction is allowed in temperatures of -10.

5.Strong durability: This product is an inorganic cementing material, and its service life is greater than that of the foundation concrete. After millions of fatigue tests, there was no significant change in the intensity of 50 freeze-thaw cycles. After 30 days of immersion in engine oil, the strength is significantly improved.

Third, the use of the product.

1.It is suitable for machine base, anchor bolts and other equipment foundation grouting.

2.Reinforcement, repair and reinforcement of beams, slabs, columns, foundations, floors and roads of buildings.

3.It can be used for anchor bolts and steel bars for anchor bolts and structural reinforcement.

4.Embedding of construction joints in subway, tunnel, underground and other projects.

5.As well as the secondary grouting book of the fixed connection between the steel structure (rails, steel frames, steel columns, etc.) and the foundation.

Fourth, the reference dosage.

The reference consumption is calculated on the basis of tons and cubic meters, and the actual consumption is calculated.

It is precisely because of the high strength of the grout, far exceeding the strength that the cement can achieve, and changing the shrinkage characteristics of the cement when curing, so it is called high-strength non-shrinkage grout!

There are different types of grouting materials, such as CGM grout, DGM, high-strength non-shrinkage grout, etc., which are determined according to the standards of different building research institutes, and do not mean that the product is bad, and the specific use needs to be tested.
