Product Overview
Highway bridge slurry is a special product for post-tensioning pre-stressing pipe (hole) slurry construction, which is optimally formulated from a variety of high-quality cement-based materials and high-performance additives. This material has excellent fluidity, slurry stability, good filling degree, adjustable setting time, non-shrinkage, micro-expansion, high strength and does not contain harmful substances to the reinforcement and other characteristics.
The use of aperture slurry can ensure the bond between prestressing tendons and concrete, so that the prestressing reinforcement can effectively transfer the force, and also provide protection to the prestressing tendons, preventing them from corrosion, thus improving the durability and safety of the structure.
In addition, the aperture slurry also has a low water-to-cement ratio, high fluidity, suitable setting time, strong stability, no water secretion, early strength, high strength, high fracture resistance, micro-expansion properties and non-shrinkage, etc., and these characteristics make it widely used in the construction industry, especially in a variety of railroads, highway post-tensioning pre-stressed bridges, such as aperture slurry projects!

Performance parameters of grout
Usage Method
1: Flushing the hole
The hole should be flushed with pressure water before slurrying, in order to exclude the powder slag and other debris in the hole, and ensure that the hole is smooth, after flushing, use the air compressor to blow away the water in the hole, but keep the hole wet and make the cement slurry combine well with the hole wall, in the process of flushing, such as water bubbling and leakage phenomenon, it should be timely plugging the loophole to deal with it.
2: Cement paste mixing
① cement paste should have enough fluidity, fluidity of 15:~ 20mm to meet the grouting requirements.
② The water used for water and gray slurry should be clean water, not containing substances harmful to cement or prestressing steel strand.
3: Mixing of cement slurry:
The mixing ratio of cement slurry is determined by trial mixing before mixing, or it can be determined according to the previous mixing ratio retest. For the mixing of cement slurry, firstly add water into the mixer, turn on the mixer and then add the pressurized slurry, and the material measurement should be based on the weight of the pressurized slurry to calculate the water dosage. The mixing time should ensure that the cement slurry is evenly mixed, which generally takes about 3min. During the grouting process, the mixing of cement slurry should be uninterrupted, and when the grouting process stops for a short period of time, the cement slurry should be allowed to circulate in the mixer and the grouting machine, so as to prevent blocking the pipeline and the switching valves after precipitation.
4: After the prestressing strand is tensioned, the aperture should be grouted as early as possible and in time. Aperture grouting is to use grouting pump to press and pour cement slurry into the prestressing tendon aperture, so as to fill the gap between prestressing strand and aperture, and let the prestressing strand and concrete firmly bond as a whole. The aperture is grouted in time, and the grouting process: the grouting generally adopts the piston grouting pump, and the pressure of grouting is subject to ensure that the cement slurry pressed into the hole is compact, and the maximum pressure of grouting should be controlled at 0.5-0.7Mpa, and the pressure should be appropriately increased in the case of one-time grouting, but the maximum pressure should not be more than 1.0Mpa.
5: Grouting should be carried out slowly, evenly, without interruption, the beginning of the pressure should be small, gradually increase the pressure, grouting should be achieved at the other end of the aperture vent hole full and out of the thick slurry (should be the same consistency with the provisions of the cement slurry) until, and then use the bolts plug plug the slurry outlet. In order to ensure that the orifice is full of mortar, after each orifice is grouted to the maximum pressure, a stabilized pressure period, which is generally not less than 0.5Mpa, should be maintained, and this stabilized pressure period should not be less than 2min. close the valve of the inlet, and the grouting machine will return to the grouting machine, and then dismantle the connecting joints and clean up instantly after the cement slurry is solidified.
:6: In order to check the actual density of the cement slurry in the borehole, the compactness of the slurry should be sampled from the inspection hole after the slurry compression, if it is not solid it should be dealt with in time, and the method of treatment can be used for secondary grouting. At the same time of mixing cement slurry, make standard test block, after the same conditions as the beam maintenance. Compressive strength of cement slurry: the strength of cement slurry shall not be less than M30 grade, and the test block of cement slurry shall be made by cubic mortar test mold with side length of 70.7mm.
