Yjl-101 grouting materia   

Yjl-101 grouting material is a kind of product used for post tensioned prestressed hole (pipe) grouting construction. It is made of a variety of high-quality cement-based materials and high-performance admixtures. It has the characteristics of excellent fluidity, stable slurry, good filling degree, no shrinkage, micro expansion, high strength and no harmful substances to reinforcement.

Application:

This product is widely used in cement paste, mortar and concrete grouting materials, especially for post tensioned bonded prestressed concrete duct grouting and design foundation, anchor rod and other large-scale projects such as highway, highway, municipal road and bridge, power station and other large-scale projects. It can also be used to repair the defects of concrete loose, cracks and holes.

Product features:

1. Good fluidity, high strength, no bleeding, no segregation and no stratification.

2. Micro expansion characteristics, strong plumpness of grouting and firm bonding with concrete.

3. With high filling degree, it can be used for one-time grouting construction, and the pipeline grouting is tight without pores.

4. Good durability, aging resistance, no corrosion to the reinforcement.

usage method:

1. The water binder ratio is 0.26-0.28, which can be adjusted according to different grouting positions.

2. The speed of mixer shall not be less than 1000r / min.

3. The mixing sequence is: start up, add water and press slurry.

4. During construction, under high temperature conditions, the time with lower temperature should be selected, such as night construction; under low temperature conditions, construction should be carried out according to winter construction standards.

matters needing attention:

1. Suitable temperature is from + 5 ℃ to + 35 ℃

2. Mixing equipment: it is recommended to use the slurry mixing equipment in accordance with the requirements of "technical code for construction of highway bridges and culverts" (JTG / tf50-2011).

3. Slurry storage: avoid static storage and keep the best flow rate by stirring at low speed.

4. Grouting: it is recommended to complete the grouting within 40 minutes. The fluidity of cement slurry with reduced fluidity due to delayed use shall not be increased by adding water.

Storage conditions and duration:

Sealed and stored in dry and ventilated indoor conditions, it can be stored for 6 months.
