Concrete Repair
What is Concrete, Exposed Concrete and Its Importance in Today's Architecture
Concrete is at the forefront of the construction industry's most fundamental building materials. Over the last century, it has had a greater impact on architecture than any other material. It is also the most modern and economical building material of our time. Concrete was renowned for its high load-bearing capacity, formability, and versatility. Now, it also attracts the attention of designers with its wide range of visual impacts and textures.
Concrete is one of the leading building materials that is formed by homogeneously mixing cement, water, aggregate and chemical additives, and first has a formable consistency, then hardens and hardens, giving durability to the surfaces on which it is applied, and is the basic element of architectural applications.
Today, we see traces of concrete in many structures: buildings, bridges, dams. It's rumored that more than 10 billion cubic meters of concrete are produced globally each year. This makes concrete the most produced and consumed material after water.
Fair-faced concrete, on the other hand, is more than a material in itself; it embodies an architectural expression of concrete. It is also used as a term for the unprocessed state of concrete. Fair-faced concrete is more fluid and durable than conventional concrete. With no paint, plaster, or exterior coating applied to its surface, the resulting concrete is smoother than other concretes when the formwork is removed. The aggregates in fair-faced concrete are smaller than those in conventional concrete.
Successful concrete production depends on the pouring, placing, and compaction of the concrete, including cement, aggregate, water, and coloring. To achieve a smooth surface when using exposed concrete, the mold and mold workmanship are just as important as the production of the prepared concrete. The mold is crucial for supporting and shaping the fresh concrete, and ensuring the desired surface smoothness of the concrete.
Despite the durability of concrete, many surface defects can develop due to time and environmental factors. Numerous problems can arise, including surface cracks, segregation, concrete loss, and corrosion. The materials used to repair concrete surfaces are crucial for resolving these issues. However, not every repair material can be applied to every concrete surface. Therefore, it's best to examine the concrete's characteristics and properties and apply the repair material to the appropriate concrete surface.
In this section, we see that the two products are produced under the names of Concrete Repair 800 and Concrete Repair Fine, with their environmentally friendly and effective high-performance formulations; one is produced for deep repairs on the concrete surface and the other is produced to prevent aesthetic deterioration on the surface;
Concrete Repair 800 is a coarse-grained repair mortar formulated to protect against corrosion and extend the life of structures. Its fiber-reinforced structure is effective against issues such as segregation and surface loss, which affect durability on concrete and exposed concrete surfaces. Its polymer reinforcement and high adhesion strength make it resistant to a variety of temperature conditions and frost. When multiple layers are required, it can be applied in thicknesses ranging from 5 mm to 30 mm.
Concrete Repair Fine is a finishing mortar for surface repair. Application thickness ranges from 0.5 mm to 4 mm. It is a repair mortar resistant to water, sudden temperature changes, and corrosive salts. When applied to concrete and exposed concrete, it creates a smooth and even surface. It also contributes to the aesthetic appearance of the surface by preventing air bubbles.
Concrete and exposed concrete hold a significant place in today's architecture, and therefore, the quality of its maintenance is equally crucial. All buildings deserve high-quality and affordable repairs with the environmentally friendly formulations of Concrete Repair 800 and Concrete Repair Fine.
