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 deal with pipe 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:
The ready-mixed concrete must be moistened and lubricated 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 ingredients in the concrete except aggregate
Moisturizing Is the tube agent easy to produce?
The moisturizing agent is easy to produce.
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.
Should the pipes of the concrete pump be lubricated with __________ before transporting concrete?
First fill the delivery pump with water, and then start to add mortar with the same mix ratio to moisten the pipe. The amount of mortar varies according to the length of the pump pipe. Water is best within the range of 0.5m3~2m3. Do not apply it in the column wall formwork, because failure to discharge it quickly will cause concrete defects. Do not apply the mortar in the same part. It is best to pour a little into the column wall in front. The theoretical thickness should not be greater than 50mm. The excess can be used for other purposes.
How to pour pipe mortar in the floor slab?
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.

days Pump operating tips?
1. Site observation. When the car approaches the scene and maintains a certain distance from the target, we have to get out of the car and look at the scene to see if there are any places on the road that pose a threat to the car body, such as whether there is water on the ground and whether there are obstacles on both sides of the road. Only by careful observation can objects block the passage of engineering vehicles, whether there are metal protrusions on the ground, whether the driving roadbed is firm, whether there are low-altitude lines in the sky, whether the requirements for erecting the vehicle can be met, etc. to ensure that no accidents occur during the initial operation.
2. After passing the above inspection, the engineering vehicle can be allowed to enter the construction site. Can be opened��The system is converted to parallel erection of the vehicle. When opening the four support legs, first check whether the support legs are locked by fixed locks. If so, open them. There are several points that must be paid attention to when opening the legs. 1. Look around the construction first. Communicate with the construction personnel to determine the geological structure under the legs so that we can find a plan when stepping on the feet. 2. Understand the construction scope, determine which leg is the main force-bearing leg, and take precautions when stepping on the foot. 3. The design of the car is strictly calculated. You cannot use less padding or open less legs because of laziness. All four legs should be opened as much as possible. The opening range will be evaluated on site. 4. The geological structure under the support legs cannot be hollow or have thin cement structures, such as sewer cement board cover surfaces. If this is not possible, you can negotiate with the construction party to add steel plates on the ground.
3. If the above check is correct, you can use the remote control to open the boom. Select the boom direction. There should be no obstacles within one meter of the boom. If you encounter a special site, you can use the slow gear to open the boom. When starting, keep your eyes on the boom and observe whether the four supporting legs are stable. After the boom is unfolded and arranged, check whether there is water in the conveying cylinder and whether there is sufficient grease.
4. After completing the basic matters, let the tanker pour the pipe moistening mortar into the feed port. Points to note when making mortar: 1. It should not be too dry or too thin. The criterion is to observe that the released slurry is smooth and does not splash. This is because dry slurry will form into lumps and not flow smoothly, while thin slurry will be like water when it comes out. Splashing and unqualified slurry can easily cause pipe blockage. Generally, about one side of pipe mortar is enough. Then the concrete truck is poured and the pump operator arrives at the construction target location. After confirming, open the pipe and set the pipe level. Zoomlion generally uses 3 to 4 files.
5. When the pump operator cooperates with the maintenance personnel, he should not be affected by the environment and become nervous during operation. In operation, he can push fast and pull back slowly, and find the pause point when the boom moves and loosen the keyboard. , can ensure the stable operation of the boom, and only listen to the instructions of the support personnel in operation.
6. When retracting the boom, my key point is to retract the boom from where it is raised, because the direction found at that time is the best, and there is no space for obstacles. When raising the jib, novices must not take their eyes off the jib until the jib is completely restored. </p
