Micro Concrete: How is it Used in Concrete Construction?

🕑 Reading time: 1 minute

Micro concrete, also known as micorconcrete or MicroConcrete, is a cement-based coating applied to various surfaces like tiles and woods to provide the look and feel of concrete at a fraction of the weight and cost of real concrete. It is a cost-effective method of achieving aesthetically appealing surfaces.

The thickness of applied micro concrete is around 2 mm to 3 mm. The material surface is anti-slip, mold-free, hygienic, and stain-free. That is why it is an excellent option for bathrooms, kitchens, and floor surfaces.

How is it Different from Conventional Concrete?

1. Ease of Handling and Placement

Micro concrete is commonly available in a prepackaged mix, making it easy to prepare and place without skilled labor. On-site concrete mix preparation is not required, and, subsequently, human errors are reduced completely. Therefore, it is an easy surface choice for almost any environment where a faux concrete finish is desired. Micro concrete is suitable for those with restricted space and limited concrete-laying skills.

2. Reduced Water Demand

Initially, micro concrete was developed to decline water demand compared with normal concrete. The material's ability to establish a good bond makes it desirable for repairing aging or cracked concrete structures. Moreover, micro concrete reduces the cost of concrete repair since it does not need heavy machinery like pumps to place.

3. Fast Drying

Micro concrete dries quickly, and the covered surface can be functional within a day. This makes it an ideal choice for designers and homeowners who want to decorate the surface in their buildings without disruption.  

How to Apply Micro concrete?

1. Surface Preparation

The surface over which micro concrete needs to be applied is firstly prepared, which involves washing, cleaning, and removing dust, dirt, gravel, or chemicals. Water, acids, or water blasting can be used to clean concrete surfaces. Corroded materials and steel bars should be cleaned and coated before the application of micro concrete.

2. Mixing

Micro concrete mix can be prepared manually, but a mixing vessel should be considered if a large quantity is needed. The required water quantity may vary based on the mix, but it is commonly around 1:8 water to micro concrete. The mixture is prepared by gradually adding micro concrete to the water while it is being stirred constantly.

3. Pouring

The mix should be placed as soon as possible for the best consistency and flow. After that, use suitable tools to smoothen the mixture out and permit it to dry.

Advantages

1. Easy to apply; compaction is not required; hence, heavy machinery is not needed.
2. Creates a good bond with almost all surfaces.
3. Develops good strength once it is applied on a surface.
4. Does not suffer from shrinkage, which means no cracks or folds will occur.
5. Free from chloride and consequently provide a safe and durable surface.
6. Micro concrete has low permeability, making it a perfect choice for outside surfaces, kitchens, and bathrooms.
7. No extra additives are required.
8. Excellent mold resistance.
9. It can be colored.

Applications

Micro concrete has been used in several applications, both commercial and residential buildings. It offers a durable, contemporary, and seamless finish. 

The micro concrete can be used for outdoor and indoor surfaces due to its high durability, such as foyers, hotels, shopping centers, open plazas, museums, office Centers, garages, general interior surfaces. 

It provides cost-effective and hard-wearing concrete aesthetic walls and floors. In addition, it is a watertight material and therefore suitable for bathrooms and splashbacks in kitchens.
