What are the common defects in concrete?
Concrete Defects
- Freeze-Thaw Effect: Concrete is very strong in compression but relatively weak in tension.
- Chemical Attack: Chemical attack can occur because concrete is alkaline and chemically reactive.
- Crazing:
- Scaling:
- Blisters:
- Spalling:
- Dusting:
- Foreign Objects:
What are four 4 types of concrete surface finishes?
In a moment you become aware as to the four basic types of concrete finishes – Slick Finished Concrete, Broom Finished Concrete, Exposed Aggregate Concrete and Stamped Concrete.
What are the different types of surface deterioration in concrete?
Different types of Deterioration in Concrete Structures
- Different types of Deterioration in Concrete Structures.
- Corrosion of Embedded Metals in concrete.
- Freeze thaw deterioration in concrete.
- Chemical attack in concrete.
- Alkali-Aggregate Reactivity in concrete.
- Abrasion Erosion in concrete.
- Plastic Shrinkage in concrete.
What is the most common form of concrete deterioration?
Fig. Corrosion of reinforcing steel is.
What are the 5 structural problems of concrete?
Problems with concrete include construction errors, disintegration, scaling, cracking, efflorescence, erosion, spalling, and popouts.
What are the defects of poor construction slab in a project?
These defects in concrete structures can be due to poor construction practices, poor quality control or due to poor structural design and detailing. Common types of defects in concrete structures are honeycombing, form failure or misalignment of formwork, dimensional errors, rock pockets and finishing errors.
What is the texture of the concrete surface?
On the concrete patterns can be made like different size arcs and swirls. Depending on the tool used to impart the pattern, the texture created can be medium, smooth or coarse. The coarse texture is created by wood floats and smooth finishes are created by aluminum floats.
What is defects due to deterioration?
Defects may be broadly divided into those due to the construction, due to environmental attack or due to the loads applied to the structure. ‘Deterioration’ refers to a more general loss of performance.
What causes damage to concrete?
Concrete can be damaged by fire, aggregate expansion, sea water effects, bacterial corrosion, calcium leaching, physical damage and chemical damage (from carbonatation, chlorides, sulfates and non-distilled water). This process adversely affects concrete exposed to these damaging stimuli.
What causes concrete to deteriorate?
Concrete degradation may have various causes. Concrete can be damaged by fire, aggregate expansion, sea water effects, bacterial corrosion, calcium leaching, physical damage and chemical damage (from carbonatation, chlorides, sulfates and non-distilled water).
What is concrete texture?
The concrete texture is the finish that they required no added material to produce. Stamped concrete is commonly referred to as texture or imprinted concrete or the concrete which is designed to resemble slate, brick, flagstone, stone, and tile. There is a huge number of finishes and textures.
What are the types of concrete defects?
The most common concrete defect is the crack. Cracks are when the concrete separates. Cracks can be horizontal, vertical, and both horizontal and vertical. Crack horizontal width, vertical height, and on-going activity matter a lot when determining whether and how to deal with the crack.
What are surface defects?
Surface Defects. Surface defects are the boundaries, or planes, that separate a material into regions, each region having the same crystal structure but different orientations. There are different kinds of surface defects, some of which are described: The exterior dimensions of the material represent surfaces at which the lattice abruptly ends.
What is the definition of concrete defects?
Delamination is a defect in hardened concrete which is defined as a discontinuity of the surface concrete which is substantially separated but not completely detached from concrete below or above it. Visibly, it may appear as a solid surface but can be identified as a hollow sound by tapping or chain dragging.
What are coating defects?
Cratering, a coating defect, is the formation of small bowl-shaped depressions in a coating film. These depressions frequently have drops or bands of material at their centers and raised circular edges.
