How to Repair Cracks in RCC Slab
The cracks in the reinforcement concrete slabs (RCC slabs) refer to those openings or fissures which have been developed in the concrete structure. The cracks in the RCC slabs have varied in size and severity. It is necessary to understand the types and causes of the cracks to determine the methods for repairing the cracks in the RCC slabs.
Structural cracks
Structural cracks of the RCC slabs refer to those cracks which can impact the structural integrity and load-bearing capacity of the RCC slabs.
Horizontal Cracks
These horizontal cracks have been found on the beam-column junction of the RCC slab which occurs due to insufficient reinforcement.
Diagonal Cracks
This type of crack has been observed along with the height of the reinforced concrete slab which impacts the slab’s integrity.
Splitting Cracks
This type of cracks are short and parallel which occurs when the column has inadequate steel reinforcement.
Corrosion Cracks
These types of structural cracks have appeared near the reinforcement lines on the columns.
Flexural Cracks
The flexural cracks have occurred due to the flexing or bending of the RCC slabs which has been found near the load-bearing areas.
Overloaded Slab Cracks
This type of structural crack has occurred in the case the excessive weight has been placed on the RCC slab during snowfall or heavy rain.
Non-structural cracks
The non-structural cracks of the RCC slabs are narrower which only affects the surface layer of the RCC slab.
