Grouting material common grouting

what are the common grouting methods grouting material? Because of the grouting material with strong liquidity, so used for plugging, effect is better. Today, however, the key is to introduce several kinds of grouting method, hope to help you use after grouting material.



the first funnel method is high, high funnel method is grouting material in construction, only by grouting material cannot satisfy the requirement of liquidity, using the grouting of potential difference, meet the requirements of the grouting method. The method is suitable for large equipment base, Side length more than 3 m) The grouting. At this point, to decorate the appropriate vent in the equipment base, vent is not less than 30 mm in diameter. Box below the base and the base for slotted equipment also should use the way of grouting.



is another kind of method, weight is in the construction of grouting materials, the use of its characteristics of liquid, the free flow of grouting scope, meet the requirements of the grouting method, used in the foundation of the equipment surface relatively flat secondary grouting of the equipment.



finally there is a kind of method is the pressure grouting method, pressure grouting method is in grouting material construction, the grouting pressure equipment, to meet the requirements of the grouting method. The method adapted to the complex structure and concrete grouting, the grouting pressure equipment must be used.



that is about the grouting materials commonly used several kinds of grouting method in detail, and concrete in used in construction, which method is better, and need staff to choose according to actual situation.

grouting materials commonly used in grouting method

what grouting material is the common grouting methods? Because of the grouting material with strong liquidity, so used for plugging, effect is better. Today, however, the key is to introduce several kinds of grouting method, hope to help you use after grouting material.

the first funnel method is high, high funnel method is grouting material in construction, only by grouting material cannot satisfy the requirement of liquidity, using the grouting of potential difference, meet the requirements of the grouting method. The method is suitable for large equipment base, Side length more than 3 m) The grouting. At this point, to decorate the appropriate vent in the equipment base, vent is not less than 30 mm in diameter. Box below the base and the base for slotted equipment also should use the way of grouting.

is another kind of method, weight is in the construction of grouting materials, the use of its characteristics of liquid, the free flow of grouting scope, meet the requirements of the grouting method, used in the foundation of the equipment surface relatively flat secondary grouting of the equipment.

the end there is a kind of method is, by the method of pressure grouting pressure grouting method is in grouting material construction, the grouting pressure equipment, to meet the requirements of the grouting method. The method adapted to the complex structure and concrete grouting, the grouting pressure equipment must be used.


the summer using grouting material note

the summer air temperature is higher, and easy to wind, the air is dry, so will cause certain influence to the construction of grouting material. Therefore, in order to avoid these problems affect the construction, in the summer when using grouting material must pay attention to the following questions.

in the first place, need to pay attention to when pouring, template, reinforcing bar, second time grouting material at the grass-roots level shall sprinkle wet, cool, segmented layered reasonably, even at the same time make the old and new casting time interval shorter. For high slump concrete grouting material mixture, should use high efficiency water reducing agent, some high efficiency water reducing agent of big mixture slump can maintain two hours.

second, also need to control the delivery time, should try to shorten the external transport time on transportation problem, control the transportation distance. After grouting expect at site shall be immediately unload material and casting, avoid staying time is too long cause larger slump loss. Internal transport by pumping, pipeline should be covered with wet cloth.

in the end, the aggregate and the mixing water should avoid direct sunlight, water spraying cooling the aggregate. Had better use the well water mixing water, such as water storage tank, should avoid direct sunlight. To aggregate in the heap sprinkler, lower the temperature of the grouting material of concrete aggregate, should avoid grouting material mixture temperature 30 ℃, with ice when necessary to reduce the temperature of the secondary grouting material mixture.
