Product Description
The development of cracks in concrete structures is determined by detecting the increase in the number of cracks, and the increase in the length, width, and depth of the cracks.
Analysis of Crack Causes
Internal factors: Defects in the quality of concrete structure and component materials, insufficient cross-sectional dimensions, design, construction, and maintenance errors, etc.
External factors: Structural overload, displacement constraints, temperature, shrinkage, creep effects, disaster damage effects, etc.
Note: Cracks in concrete structures and components due to insufficient bearing capacity are only a surface symptom and structural response of the decline in the bearing capacity of the structure and components, and are not the substantive cause of the decline in their bearing capacity. Therefore, it is impossible to restore their bearing function through simple crack repair.
The Role of Crack Repair
(1) Resist the invasion of media that induces steel bar corrosion and extend the service life of the structure;
(2) Maintain the integrity of the structure and components by strengthening the concrete;
(3) Restore the functional use of the structure, its waterproof and impermeable capabilities;
(4) Eliminate the psychological pressure that cracks cause to people;
(5) Improve the appearance of the structure.
II. Crack Repair Materials
Performance Characteristics
Very low viscosity and strong penetration ability, and can enter micro-cracks with a width of 0.1mm.
Good resistance to media (acid, alkali, water). Does not contain volatile solvents and does not shrink when hardened. Toughness and impact resistance after curing.
