BASF MasterFlow872 double shrinkage high fluidity precision grouting material

Double shrinkage compensation high-strength, high-fluidity precision grouting material
Overview
A precision grouting material containing selected natural aggregates that has shrinkage compensation functions in both the plastic state and the hardened state. The grout has high flowability, excellent early and late strength, and maintains excellent working properties at higher temperatures when mixed and left at the recommended consistency. Contains no chloride.
Recommended Applications
All precision, non-shrinkage grouting applications with grout thickness
and above
Critical equipment bases, base plates and column bases
Nuclear power plant equipment
Papermaking and pulp equipment
Heavy rotating equipment
Generators and steam turbines
Advantages and features
Comply with national standards/, type II technical requirements
High strength in the later stage ensures that the equipment operates in static and medium conditions The equipment operates safely and stably for a long time under high dynamic load
Excellent fluidity makes it easy to pour into a narrow space to ensure the maximum bearing area
The extended working time facilitates one-time filling or intermittent filling of large-scale packages one after another. and equipment that is difficult to grout
Dense, non-shrink grouting without segregation or settlement, ensuring close contact between all grouting surfaces and equipment
Simple mixing and easy to use

Typical performance indicators
The strength and fluidity of the grouting material depend on the amount of water added, the ambient temperature and the curing and age of the grouting after hardening. Typical strength and fluidity data are as follows

Performance data are typical data and are based on a controlled temperature of ℃ Laboratory environment. Construction site data may fluctuate due to actual conditions on site. Both field and laboratory testing should be based on the required flow rate rather than strictly on the water consumption range given. If the project requires strength testing, do not use cylindrical molds.
