Over the years, concrete has become one of the preferred paving choices after asphalt. Its smoothness, reliability, durability, and aesthetic look make it an ideal choice for pavement installation in both residential and commercial properties. However, despite its robustness, concrete pavement is deemed to crack and deteriorate if there are errors made during the concrete paving process.
If you see cracks in your concrete pavement right after the pouring process, there can be several reasons. One of them is the effect of internal and external loads on the drying solution. Corresponding damage can also occur due to improper concrete installation and inadequate material use. Moreover, some other reasons for concrete cracking are:
- When forming the concrete structure, paving contractors did not consider the geological conditions of the area.
- The structure of the solution was disturbed due to dilution with water.
- The temperature stipulated by the technological standards was not maintained.
- Technical properties and characteristics were violated during the concrete delivering process.
- Lastly, an insufficient amount of reinforcement can also cause cracks in the drying solution.
Varieties Of Concrete Damage
Splits can form in concrete as it dries. Such defects are caused by calculation errors, which compromise the surface’s structural integrity and affect the user’s safety.
There are several types of structural splits:
1. Damage Resulting From Plastic Shrinkage of the Mortar
This arises due to the rapid evaporation of the liquid present in the building mixture. Structural cracks are also formed as a result of natural shrinkage of the concrete structure.
2. Temperature and Shrinkage Defects
When the concrete hardens, a chemical reaction occurs between the cement and the liquid, producing heat. Thermal stress increases as a result of the lack of freedom to distort the concrete structure. In this case, the resistance to stresses that compress and stretch the drying mass leads to cracking.
3. Damage Caused By Drying of Concrete
Corresponding cracks appear in those places where there is no reinforcement. The main reasons for their formation are:
- An excess of liquid.
- The use of low-quality aggregates.
- A violation of the mixing technology of components.
4. Damage Caused By External Factors
Improper preparation for construction work and unfavorable climatic conditions can cause sudden shrinkage of concrete and the formation of cracks. The negative natural factors include snowfall, showers and flooding, rising groundwater, and sudden temperature changes.
How Can the Defects Be Prevented?
When pouring concrete, it is essential to adhere to existing and technological standards strictly. All the necessary components in the required proportions must be included in the composition of the building mixture. When preparing the solution, it is crucial to consider its condition and the place of pouring. Thus, it is worth paying attention to the following points:
1. At low external temperatures, the building mixture may become covered with a frozen crust. To prevent this, specific chemical substances must be added to the solution to prevent it from freezing.
2. When working in heat, concrete hardens quickly. As a result, moisture evaporates quickly, causing a change in the structure of the solution. This promotes the formation of cracks. To protect the concrete from cracking, it must be wetted with water.
3. When pouring concrete, it is crucial to observe the required temperature regime. It is not recommended to exceed the permissible amount of liquid in the solution. Excess water provokes additional vaporization. Because of this, the surface hardens faster. This leads to the formation of cracks.
4. The process of choosing cement should be approached responsibly. The quality of this component affects the behavior of the concrete mixture during the curing period. Also, it is necessary to consider the properties and characteristics of the soil on which the work is carried out.
5. Along with this, it is worth correctly reinforcing the concrete structure. An insufficient number of reinforcing elements or a violation of the frame’s manufacturing norms can cause cracks.
6. After pouring concrete, it is necessary to inspect the surfaces of the built structure periodically. Timely identification of damages in the early stages will allow you to quickly and efficiently eliminate the problem.
