Ten mistakes when working with concrete

The construction of structures using this material requires a step-by-step process in a specific sequence. Therefore, it is crucial to adhere to the technology stipulated by construction regulations. A list of other common errors can be summarized as follows:
Ignoring geodetic surveys and incorrectly calculating foundation markings lead to structural defects and misaligned corners. Therefore, it is advisable to engage professionals at this stage.
- Errors in Concrete Mix Preparation
In this situation, it is important to pay attention to the quality of the material used. Cement must be selected in accordance with the established technology grade. Avoid skimping on materials and using dirty sand, crushed stone, and reinforcing elements in the mortar. It is also strictly prohibited to dilute the ready-mixed concrete with water.
- Incorrect Foundation Preparation
When constructing a structure, it is necessary to prepare the site, mark its perimeter, and clear it of debris and excess vegetation. Failure to maintain a clean surface will result in an unstable and fragile structure.
- Using poor-quality or old formwork
Professionals recommend using reliable formwork systems with the required density and rigidity. The use of ties and supports is also recommended.
- Common mistakes when pouring concrete
Failure to follow the pouring technology includes using a building mix that is too fluid, with an incorrect water-cement ratio, and ignoring vibration during concreting. This will result in voids, poor adhesion to the reinforcement, and concrete delamination.
This problem will lead to cracks in the structure due to shrinkage caused by temperature changes. Therefore, it is important to plan the installation and execution of this stage in advance.
- Incorrect concrete vibration
The mixture is placed in layers, with simultaneous mixing and compaction using a vibrator. This "push[s]" the air out of the concrete.
- Failure to take weather conditions into account
Concrete work is not recommended in severe frost, windy, or rainy weather. If rescheduling is not possible, then special chemical plasticizers, thermal covers, and other coverings should be used in the concrete mix.
- Failure to properly cure the concrete
This error leads to the mix drying out, resulting in deformations and other structural defects. It takes at least 4-7 days for the concrete to harden in the formwork. In hot weather, the surface is watered to maintain moisture, and in cold weather, it is insulated.
- Lack of technical supervision
This error often occurs when doing concrete work yourself. Therefore, it is important to hire professionals who will provide supervision.
How to Avoid Mistakes in Concrete Work: A Summary
