It is crucial to ensure that the subgrade is free from any organic materials, debris, and large stones that could affect the stability and strength of the concrete. The subgrade should also be properly compacted and leveled to provide a smooth and even base for the concrete.
2. Formwork
Formwork is essential for holding the concrete in place while it cures. The formwork should be constructed with strong and rigid materials such as timber or steel. It should also be properly leveled, aligned, and securely braced to prevent any movement during the pouring and curing process.
3. Placing of the Concrete
Once the formwork is in place, the next step is to place the concrete. The concrete mix used for granolithic flooring typically consists of a mixture of cement, sand, aggregates, and water. A plasticizer may be added to improve workability and reduce the amount of water needed. The concrete should be mixed in the required proportions, and care should be taken to ensure that it is evenly distributed and compacted within the formwork.
4. Granolithic Topping
Once the concrete has been placed, a granolithic topping is applied to the surface while the concrete is still wet. The granolithic topping is a mix of cement and hard-wearing aggregates, such as granite or quartz, which give the floor its characteristic speckled appearance. It is spread over the surface of the wet concrete and then troweled and floated to create a smooth and level finish.
5. Troweling and Floating
The troweling and floating process is an essential step in laying insitu granolithic concrete flooring. It helps to compact the concrete, remove any surface imperfections, and bring the cement paste to the surface. This creates a smooth and dense finish, which is necessary for the durability and wear resistance of the floor.
6. Curing
Curing is the process of maintaining the moisture and temperature conditions of the concrete for a specific period to allow it to gain strength and durability. In the case of insitu granolithic concrete flooring, curing is usually done by covering the surface with a plastic sheet or wet burlap and regularly moistening it for at least 3 days. This allows the concrete to cure slowly and evenly, avoiding any shrinkage or cracking.
7. Finishing
The final step in laying insitu granolithic concrete flooring is finishing. Once the concrete has fully cured, the formwork is removed, and the surface is cleaned and washed to remove any excess cement and loose materials. The surface is then sealed and polished using a power trowel or grinders to enhance its appearance and improve its durability.
In conclusion, laying insitu granolithic concrete flooring requires proper preparation of the subgrade, constructing strong and rigid formwork, placing the concrete and topping, and finishing the surface. With careful attention to each step of the process, insitu gran
Material for Granolithic Concrete Flooring
