1.After pouring,the intensity,of 1-3 days can reach more than 30MPa,and shorten the construction period.

2.The site just add water mixing mortar can fill all the gaps,to meet the requirements of grouting engineering,ensure no vibration,long distance grouting construction.

3.Micro expansion,contraction,and reinforced grip wrapped force ensure foundation of anchor bolt and the base (steel structure) and new and old concrete structure combined firmly.

4.High durab1lily:2 million times fatigue test,50 freeze-thaw cycles test,no significant changing.

5.After soak in the oil 30 days its strength increased more than 10%,forming dense body,anti permeability without any affecting.


注意事项
Notes

1.基础处理:清扫设备基础表面,确保无碎石、灰尘、浮浆、油污、脱模剂等杂物,灌浆设备基础表面充分润湿,但不能有明水。

2.确定灌浆方式:本产品具有较高的自流性能,一般情况下,用“自重法灌浆”即可,完全依靠浆料白重白流平即可完全填充灌注空间;如果灌浆面积较大、结构特别复杂或空间很小而灌浆距离很远时,可采用“高位漏斗法灌浆”或“压力法灌浆”,以确保浆料能够充分填充各个角落。

3.支模:根据确定的灌浆方式和灌浆施工图支设模板,模板定位标高应高出设备底座上表面至少50mm,模板必须支设严密、稳固,以防松动漏浆。

4.灌浆料的搅拌:本产品水料比为0.12~0.15:1,可根据施工现场要求进行试配选择;采用机械搅拌时,搅拌时间一般为1~2min,采用人工搅拌时,宜先加入2/3的水流拌2min,其后在加入剩余的水搅拌至均匀。

5.灌浆:

(1)设备基座灌浆定,不得从四面灌浆,浆料应从一侧灌入,直至另一侧溢出为止,以利于排出设备基座与混凝土之间的空气,使灌浆料充实。

(2)灌浆开始后必须连续进行,不得间断,应在最短的时间内完成灌浆。

(3)灌浆过程中不宜振捣,可用竹条等进行拉动导流。

(4) 每次灌浆厚度不宜超过100mm 。

(5)较长设备或者轨道基础的灌浆,应采用分段施工,每段长度以5m为宜。

(6)灌浆过程中如出现泌水现象,可布撒少量干料,吸干水分。

( 7) 在灌浆施工过程中直至脱模前, 应避免浆料受到震动或者碰撞, 以免损坏未结硬的灌浆结构。

(8) 灌浆过程中如出现跑浆现象应及时处理。

6.养护:灌浆完毕后30min内应立即喷洒养护剂或者覆盖塑料薄膜并加盖岩棉被加以养护,或在灌浆层终凝后立即洒水进行保湿养护;冬季施工时还应符合现行?钢筋混凝土工程施工验收规范? (GB50204)的有关规定;

1. Basic treatment:cleaning the equipment foundation surface,to ensure that no dust,mud,gravel,oil,release agent and other debris,grouting equipment foundation surface was fully wetting,but not water on surface.

2. Determine grouting method:This product has high self performance,under normal circumstances,“self gravitation method grouting”can be completely rely on slurry weight self leveling can completely fill the space perfusion;if grouting area structure is relatively large,complex or special space is very small and grouting distance far away can be used“high funnel grouting method”or“pressure grouting method”,to ensure that the slurry can be fully filled in every corner.

3. Model:according to the determination of grouting method and grouting construction plans to support the template,template positioning elevation should be higher than the equipment base on the surface of at least 50mm,the template must be supported by tight,solid,to prevent the leakage of pulp.

4. The grouting material mixing:This product material and water ratio of 0.12 ~ 0.15:1,test selection according to the requirements of the construction site;by mechanical stirring, stirring time is generally 1 ~ 2 min,using artificial mixing should be to join the 2/3 of the water mixing for 2 min and subsequently in the add the remaining water mixing to uniform.

5.Grouting

(1).Equipment foundation grouting,grouting slurry should not from all sides,poured into the side,until the other side of the overflow,facilitate discharge between the base and the concrete equipment of air,make full grouting material.

(2).After the start of the grouting must be carried out continuously,not interrupted,should be completed in shortest time.

(3).In the process of grain filling is not easy to vibration,can be used to pull the bamboo strip.

(4).The grouting thickness is less than 100mm.

(5).Longer equipment or track foundation grouting should be used in subsection construction,each length of 5m is appropriate.

(6).Bleeding phenomenon such as grouting process can use dry water dispenser.

(7).In the process of grouting construction until the release of the slurry,the slurry should be avoided to receive vibration or impact,so as not to damage the what the structure of grouting is not hard.

(8).The grouting off should betreated in tlme.

6.Maintenance:after grouting 30min should immediately sprayed curing agent or covering plastic film in order to maintain,or in the grouting layer after the end of the final set of water for moisture conservation;Curing time at different temperatures and the dismantling template time
