Size: Typically ranges from 10 mm to 50 mm thickness, customizable based on project requirements.
Grade: High-strength, typically Grade 40 to Grade 60 concrete or epoxy-based formulations.
Viscosity: Low to medium viscosity (500-5,000 cP) for injectable formulations; higher viscosity for trowel-applied materials.
Buoyancy: Neutral to slightly negative buoyancy, depending on material density (1.5-2.5 g/cm³).
Material: Polymer-modified cementitious compounds, epoxy resins, or polyurethane foams for crack injection.
Compressive Strength: 30 MPa to 80 MPa, depending on formulation and curing conditions.
Adhesion Strength: ≥2 MPa for cementitious repairs; ≥5 MPa for epoxy-based systems.
Thermal Expansion: 10-15 x 10⁻⁶/°C to match concrete substrate.
Chemical Resistance: Resistant to sulfates, chlorides, and mild acids (pH 3-11).
Cure Time: 24-72 hours for full strength, depending on temperature and humidity.
