GRAVITATIONAL MORTAR

TS-268G GRAVITATIONAL MORTAR is a rapid filling mortar of wind and sound barrier, which is developed according to the installation of the bridge deck accessory project of the passenger dedicated line. It is easy to use, convenient to operate, fast and automatic leveling by gravity infusion way, speeding up the construction progress and improving the anti-fatigue performance of the wind barrier. Gravity mortar has strong adaptability and can be applied at both high and low temperature, especially low temperature. TS-268G has good antifreeze performance and can be used under the condition of -10℃ ~ 15 ℃ and keep good early and post strength.

The main features

1. After grouting, the product's high early strength makes the requirement of adding torque can be completed within a short time so that the barrier panel can be installed as soon as possible to speed up the construction progress;

2. Non-shrinkage and late strength decrease; High fluidity; self-compacting; Strong durability; Good frost and chemical corrosion resistance;

3. This product is convenient for construction, just need add water and stir evenly. It can be operated at negative temperature and the strength still increase continuously.

Note: 

1.fter summer construction, the minimum materials temperature should be kept above 5°C within 24 hours; After winter construction, the minimum materials temperature should not be lower than -15°C;

2. The slurry temperature is 5-7°C and the curing temperature within 24 hours is -10±1°C in winter laboratory test. Before test, the test mould is keptmore than 12 hours at the curing temperature .

3. The fluidity retention time is counted from the timing of adding water.

4. Execution standard: QB/ZBJC002-2010 Gravity Mortar.


Main application:

1. Install and fill the steel base plate of wind barrier;

2. Install and fill the steel base plate of sound barrier;

3. Install and fill the steel base plate of electric pole.


CONSTRUCTION GUIDE

1. First prepare mixing equipment, templates and maintenance supplies.Then clean the construction site and fully wet it in advance but make sure there is no water accumulation.

2. Support the template and seal the template joint with plastic tape in case of slurry leakage.

3. Add water and stir with a small hand-held electric mixer for 2 ~4 minutes as per the water-to-binder ratio of 0.16±0.01.

4. Let the evenly stirred slurry stand for 1~2 minutes until the bubbles are basically disappeared then infuse. The grouting height should exceed 5~10mm of the steel plate bottom. If the slurry leaks from side block template, it is necessary to replenish the slurry in time in case of underfill.

5. Grout the evenly mixed mortar into the construction site from one direction until the construction surface is full. If necessary, use bamboo strips or steel brazing for diversion and properly vibrate or gently tap the template.

6. After the initial setting and before final setting, the construction surface should be pressed smooth and carry out the heat conservation after the final setting.

7. It is strictly forbidden to mix any admixture into the product in case of any quality problem leading by.
