In order to extend the time that concrete resists abrasion, the most effective additives are usually those types that enhance the durability and strength of the concrete. In particular the following types of additives are especially important for improving the wear resistance of concrete:

1) Silica fume (Microsilica)

Silica fume is a high-fineness silicate powder which, when used as a mineral admixture in concrete, significantly improves the compactness and strength of the concrete, thereby enhancing its abrasion resistance and durability.

2)Fiber reinforcement

Adding steel, glass, or synthetic fibers can effectively improve the crack and abrasion resistance of concrete, especially for concrete structures subjected to high abrasion and impact loads.

3) Polycarboxylate high-performance water-reducing agents

These water-reducing agents not only reduce water consumption and increase the strength of concrete but also optimize the internal structure of concrete and improve its overall physical properties, including abrasion resistance.

4)Wear-resistant aggregates

Although not a chemical additive, mixing hard, wear-resistant aggregates (such as basalt, metal sand, etc.) in concrete can directly enhance the wear resistance of the concrete surface.

5)Concrete sealer

This is a surface treatment agent; although it does not belong to the category added during mixing, after use, it can form a hard protective layer on the surface of concrete, which greatly improves the abrasion resistance and chemical corrosion resistance.

6)Wear-resistant additives

Specific wear-resistant additives, such as those containing special polymers or hard particles, can directly improve the wear-resistant properties of the concrete surface.

In addition to the addition of additives, we can also improve the wear resistance of concrete from other methods.

1)Control the water-cement ratio

Controlling the water-cement ratio is one of the important means to improve the durability of concrete. The water-cement ratio refers to the mass ratio of hydrated colloid to cement in concrete. The lower water-cement ratio can significantly improve the strength and durability of concrete. This is because a lower water-cement ratio reduces pores and defects in the concrete, which reduces the infiltration of water and external harmful substances. Therefore, when designing concrete ratios, lower water-cement ratios should be chosen as much as possible to improve the durability of concrete.

2)Strengthen concrete maintenance and protection

Concrete may be affected by factors such as physical impact, chemical corrosion, and temperature changes during its use. In order to extend the service life of concrete structures, it is very important to strengthen the repair and protection. For concrete structures that have been damaged, materials such as patching agents and anti-carbonation coatings can be used to repair and protect them. At the same time, regular inspection of the health condition of the concrete structure and timely detection and repair of potential problems can also extend the service life of the concrete structure.

3)Correct construction and maintenance

Correct construction and maintenance are the basis for ensuring the durability of concrete. In the process of concrete construction, it should be operated in strict accordance with the design requirements to ensure the quality and reliability of concrete. Meanwhile, after the concrete is poured, proper curing measures should be carried out to ensure the early strength and durability of the concrete. Common curing measures include covering heat preservation, wetting and moisturizing, and avoiding drastic temperature changes. The durability of concrete can be maximized through reasonable construction and curing measures.
