Can concrete moisturizing agent be applied into concrete?

Cannot be used in concrete

Before pumping, put a certain amount of water into the hopper of the pump truck as required (usually with an eye plate 1/ 2 or more is appropriate), then slowly and evenly add the lubricant product to the water, and stir continuously (you can open the swing valve of the pump truck, so that the swing valve of the pump truck swings back and forth in the bucket more than 3 times) until the product is completely dissolved . Then turn on the positive pump, pump out the solution in the pipe, and at the same time dump the concrete into the hopper and complete the pumping operation. The method is the same when using a ground pump, but attention should be paid to adjusting the amount of RG-H lubricant and dissolved water.

How to use pump lubricant?

How to use concrete pump lubricant: For pump trucks with a length of less than 56 meters, use one pack (300g) of pump lubricant (pump treasure) each time. First add about 30kg of water into the hopper of the concrete pump truck, and then add a pack of pump lubricating agent (300g). After the concrete tanker arrives at the site and confirms that the project, location, and strength are correct, use the pump pipe feed inlet and use the pump lubricating agent. When lubricating the pump, be careful not to pour the solution discharged after the pump into the concrete structure. The lubrication procedures must be strictly followed during the operation.

What are the specifications for handling pipe moistening mortar?

1. Processing:

If it is ordinary mortar, it cannot be poured into the foundation concrete. If it is mortar of the same condition (that is, mortar with the same strength level as the concrete), it can be poured into the concrete. middle.

2. Function:

Ready-mixed concrete must wet and lubricate the pump truck and pipelines before starting the pump.

Third, specific treatment methods:

The mortar for moistening the pipe cannot be poured in one place. You can choose any of the following mixtures: 1. Cement slurry 2.1:2 cement mortar 3. Pump cement mortar with the same mix ratio as other components in the concrete except aggregate

Moisturizing Can the pump agent be poured directly?

The use of lubricant is very simple, easy to operate, and does not require additional equipment. In order to ensure normal use and reduce concrete quality problems and pipe blockage caused by improper operation, we stipulate the following:

1. For pump trucks with a length of less than 56 meters, use one pack of pump lubricant (pump treasure) each time ( 300g).

2. First add about 30kg of water into the hopper of the concrete pump truck, then pour a pack of pump lubricating agent (300g) into the water. Stir for 1 minute, stop for 3 minutes, and then stir again. Wait for 1 minute to fully dissolve. When the solution becomes thick and lubricated, it can be used.

3. After the concrete tanker arrives at the site and confirms that the project, location, and strength are correct, start slowly unloading concrete from the other side of the pump pipe feed inlet to the hopper. When the concrete covers the transfer pump feed inlet, Pressurized pumping can begin. Try to allow all the lubrication solution to flow at the front end of the concrete pipe, through the pump pipe first, and the concrete is pushed and pumped behind.

4. When using lubricating agent to lubricate the pump, be careful not to pour the solution discharged after lubricating the pump into the concrete structure. The first few strokes of the lubricating pump solution and concrete must be The material is discharged outside the concrete formwork until the concrete does not contain wetting solution. Direct pouring into concrete structures is not allowed to prevent quality accidents.

5. The operation process must be strictly implemented in accordance with regulations. The production department and laboratory will send personnel to the site from time to time to inspect the implementation, which will be evaluated as an important part of the pump efficiency assessment.

It should be noted that when the temperature is very low, the dissolution rate of the lubricating agent may be reduced, and the stirring time should be appropriately extended. We require: stir for 1 minute, stop for 5 minutes, and then stir for 1 minute. minute.

What is concrete moisturizer?

Pump truck lubricant is the abbreviation of high-efficiency concrete pump truck lubricant. Pump truck lubricant is a new product in the concrete market. Its main function is to lubricate the pipes of the pump truck before pumping ready-mixed concrete to avoid clogging of the pump.

For the past few decades, the ready-mixed concrete industry across the country has been using water and mortar to lubricate concrete pumps. The result is neither economical nor in line with the concepts of low-carbon environmental protection, energy conservation and emission reduction. The successful development and application of pump truck lubricant has made a positive contribution to the low-carbon, energy-saving and emission reduction of the concrete industry.

Why does a concrete pump truck need lubricant?

Be careful when using it. It should not have any big impact. Nowadays, moisturizers are being used, so there will definitely be some damage. Clean them in time to minimize the damage.

1. First, ensure that the pump pipes and connecting parts of the truck pump, ground pump, and mortar pump are sealed without leaks;

2. After checking the pump pipes of the pump truck, use clean water Flush the pump so that there are no residues, debris and other blockages in the pump pipe;

3. When pumping concrete, the pump truck lubricant solution should be discharged outside the concrete formwork first, and remember not to pour it into the concrete structure;

4. After the concrete pump and ready-mixed mortar pump are pumped, the pump pipes and pump trucks should be flushed with clean water in time;

5. Use this productProtective glasses should be worn when handling products. If the product solution is accidentally sprayed into the eyes, it should be washed immediately with plenty of water

How to deal with the pipe moistening mortar poured into the floor?

Specific treatment methods:

The mortar for moistening the pipe cannot be poured in one place. You can choose any of the following mixtures:

1. Cement slurry

2. 1:2 cement mortar cement mortar

3. Pumping and concrete Cement mortar with the same mix ratio of other ingredients except aggregate

If it is ordinary mortar, it cannot be discharged into the base concrete. If it is mortar of the same condition (that is, mortar with the same strength grade as the concrete), it can be poured into Concrete.

Ready-mixed concrete must be moistened and lubricated before starting the pump. The pump truck and pipelines must be wetted and lubricated.

Extended information:

When constructing concrete, you must first pump water and mortar to clear the pipes. Obviously, the mortar and concrete that were just poured out were not mixed evenly, resulting in the bottom layer being extremely large. Part of it is sand, and the skin will peel off over time.

If the area is not large and not tight, just apply some cement slurry and brush it. If it is a bathroom, focus on waterproofing it. If the area is too large, you can only remove the formwork and pour concrete again.

High-efficiency lubricating agent for concrete pumps can be used to replace traditional lubricating mortar. It is mainly composed of polymer materials, has no effect on the setting time and strength of concrete, and does not cause corrosion to steel bars. It can be used for the lubrication pipe of all concrete pump trucks, and there is no requirement for the strength grade of the concrete.

How to clean pipes when pumping concrete?

This is different. I wonder if the pipe cleaning you mentioned is before pouring? The pouring is still complete! It is best to use the same grade of mortar before pouring. This is more beneficial when pouring! But recently, something called pump lubricant is also used in Shenyang or other places! One bag is less than 50KG. Then add the right amount of water! It can also achieve the effect of pumping mortar! If the pipe cleaning you are talking about is done by pouring, water will do! You can also use the suction ball on the car to clean it! In the south, suction balls are generally used! Hope the answer is helpful to you! </p
