Micro concrete, also known as micro-concrete or micro-repair mortar, is a specialized type of concrete used for small-scale repairs and surface restoration. It is typically used to repair damaged or deteriorated concrete surfaces, such as spalled areas, cracks, or minor structural defects. Micro concrete is a high-performance repair material with unique properties. Here are some key features and components of micro concrete:
- Composition: Micro concrete is composed of a combination of cementitious materials, fine aggregates, and additives. The exact composition may vary depending on the manufacturer and specific application requirements.
- Particle Size: The fine aggregates used in micro concrete have a smaller particle size compared to regular concrete. This allows for better workability and a smoother finish when applied to small repair areas.
- High Strength: Micro concrete is designed to provide high compressive strength to ensure the repaired areas can withstand the intended loads and stresses. It is formulated to achieve strength comparable to or higher than the existing concrete.
- Durability: Micro concrete offers excellent durability and resistance to chemical attack, freeze-thaw cycles, and abrasion. It helps protect the repaired areas from further deterioration and extends the service life of the structure.
- Bonding and Adhesion: Micro concrete is formulated to have strong bonding and adhesion properties to ensure proper bonding with the existing concrete substrate. This helps create a seamless and long-lasting repair.
- Workability: Micro concrete has good workability, allowing it to be easily mixed and applied in small quantities. It can be troweled or sprayed onto the repair area, providing a smooth and uniform finish.
- Rapid Setting: Some micro concrete products are designed to have rapid setting characteristics, allowing for quick repairs and minimizing downtime. These fast-setting formulations enable the repaired areas to be brought back into service in a shorter time frame.
- Pigments and Finishes: Micro concrete can be formulated with pigments to match the color of the existing concrete, ensuring a visually appealing
