High-performance pipeline grouting agent is a new type of admixture that is mainly composed of inorganic functional materials and compounded with organic polymer functional materials. It is non-toxic, non-flammable and contains no chlorides or other corrosive ingredients. The product fully complies with the technical requirements of the "Technical Specifications for Construction of Highway Bridges and Culverts" and has multiple functions such as efficient water reduction, reinforcement, plastic retention and bleeding reduction. At the same time, the product can cause moderate expansion to compensate for the shrinkage of the hardened cement mixture at different times.
1. Application occasions
High-performance pipeline grouting agent products are suitable for the construction of post-tensioned prestressed concrete channel grouting materials in large-scale projects such as highway bridges, railway bridges, and nuclear power plants.
, Features and Advantages
Low water-to-binder ratio: The water-to-binder ratio is only.~
High fluidity: The ability to moderately retard setting and maintain high fluidity
Micro expansion : Can cause micro-expansion of the cement mixture before and after setting, fully filling the gaps
Has high early strength: compressive strength, 3 flexural strength The material is non-toxic, odorless, and meets environmental protection requirements. Contains chloride and other corrosive ingredients.
Experimental test data: (Inspection basis: /- "Technical Specifications for Construction of Highway Bridges and Culverts")
2. Construction Instructions:
High-performance pipeline grouting agent must be trial-matched with cement before use. Determine the best mixing ratio, the recommended dosage is internal mixing, and the water-binder ratio is .~.
. Pulping: Mixing should be done with a high-speed mechanical mixer with a speed not lower than r. The mixing sequence is: first add water to the corresponding scale, turn on the mixer, add grouting agent evenly, then add all cement powder evenly After completion, stir for another 3 to 3 minutes, then introduce the slurry into the slurry storage bucket and stir until the grouting is completed.
, Grouting: Grouting as soon as possible after stirring, the usual grouting method should be adopted.
Cleaning: Clean all construction tools and equipment with water.
.Protective measures: Wear protective gloves and goggles during construction.
3. Packaging and Storage
Packed in kraft paper bags, net weight/bag. Sealed packaging, stored in dry and ventilated indoor conditions, can be stored for months
