The factory floor is an extremely important item because most activities in the production process affect the factory. Before concreting, smoothing the concrete surface or floor is a very important job that contributes significantly to the overall quality of the project. The smoothing of flat concrete is a rather complicated task that requires a high level of technical skill during the construction process.
Preparatory work for the construction of the factory floor concrete includes the following stages:
Design of concrete paths and locations: Identify routes for trucks carrying concrete to the pouring site and place the concrete at the correct location to avoid moving and repairing the pouring surface after completion.
Mark the concrete pouring area: Use measuring tape and stake to mark the concrete placement according to the required size and shape.
Site preparation: Create a flat, solid and clean surface to ensure that the concrete surface is evenly poured.
Mold installation: Install the mold according to the required size and shape. Make sure the molding is correctly placed and protected to prevent spillage of concrete.
Prepare materials: Prepare enough concrete, sand, gravel and water to pour concrete. Check the quality of the materials to ensure they meet the requirements of the concrete.
Cut drainage lines: Cut drainage lines on the concrete surface to ensure that water does not affect the strength of the concrete.
Protect non-concreting surfaces: Be sure to protect other surfaces from splashing or soiling.
Concreting: Pour concrete according to the designed size, shape and density. After pouring is complete, use the compressor to seal the concrete surface tightly.
Finish Concrete: Create a smooth and glossy surface to ensure that the concrete surface meets the requirements of the workshop.
Waiting time for concrete to harden: The waiting time for concrete to fully harden depends on many factors: concrete mix ratio, humidity and ambient temperature, thickness of concrete layer, quality of concrete concrete…The waiting time for concrete to harden is usually around 24 to 48 hours. After the concrete surface has hardened, it is possible to remove the mold and start finishing the concrete surface. However, to ensure the hardness and durability of the concrete, it is necessary to wait until at least 7 days after placing the concrete before placing the load on the concrete surface.

Step 1: Agree on the requirements of the warehouse platform, the type of warehouse platform. Agree on how to measure the flatness and balance of the warehouse floor.
Step 2: Erection of formwork: Use a hydrometer or theodolite to locate the position and elevation of the concrete pouring form according to the design.
Step 3: Concrete work: It is necessary to determine the type (grade and slump) of the concrete porch, to ensure the hardness and durability of the concrete, it is necessary to wait until at least 7 days after pouring the concrete. concrete before placing the load on the concrete surface.
Step 4: Spread and remove concrete
Step 5: Surface Checker: Use 3.05m (10 feet) super flat ruler to remove irregular concrete areas
Step 6: Use the highway straight edge tool at a 45-degree angle along the concrete pour axis and in both directions of the concrete strip to remove irregular concrete areas.
Step 7: Wait until the concrete has solidified, surface, and remove surface water with a specialized system, without affecting the flatness created from the above construction steps.
Step 8: Rub the concrete floor to create evenness with a self-propelled trowel, combining an industrial trowel with a super flat pan.
Step 9: Use highway straight edge tool (3 - 6m long) with flexible tilt angle to perfect the flatness of the surface
Step 10: Finish the surface with self-propelled trowels and industrial trowels fitted with smooth and polished blades.
Step 11: Measurement: Use the Fmin meter to read the flatness and balance of the warehouse floor. This number is usually read within 24 hours of placing the concrete
