Concrete is one of the oldest building materials used by mankind to this day. In addition to the listed advantages, concrete has one serious drawback. Over time, this material loses its former strength and becomes covered with cracks. In the future, the situation will only get worse. Therefore, it is very important to take measures even at the construction stage.
1. Correct choice of cement and correct proportions
The first and most important thing that has a direct impact on the strength and durability of concrete is the brand of the selected cement, as well as the proportions in which the material was mixed. The optimal ratio of cement to sand for most grades is 1 to 3. However, this proportion may vary depending on a number of conditions, in particular on the purpose for which the material will be used.
2. Use of plasticizers
The addition of a variety of plasticizers should not be neglected. These supplements are generally very cheap and easy to use. However, they should be used in accordance with the instructions. Otherwise, there is every chance of spoiling the cement, rather than making it better. If you add more plasticizer than necessary, then the concrete may turn out to be too dry.
3. Good old armature
Few things increase the strength of concrete as much as reinforcement. A mesh or reinforcement is used for it. Both are added to the future structure even before pouring. Today, in addition to steel reinforcement, the use of fiberglass meshes is becoming increasingly popular. However, even the addition of various small scrap metal, such as trimming pipes, nets and wire, can significantly increase the strength of the future structure.

4. Add fiberglass
Many craftsmen also recommend adding fiberglass to concrete. It will allow the screed to be maintained in the first hours and days after pouring. It is also worth noting that fiberglass today is actively used not only with cement, but also when creating plaster.

5. We use impregnation
Finally, do not forget that after pouring it is necessary to cover the concrete with a water-repellent impregnation. The formed protective layer will significantly extend the service life of the structure and protect it for a long time from the destructive action of water.
