Detailed Guide to the Nevo Flat Slab Concrete Pouring Process

Flat slab Nevo technology is becoming a trend in green construction due to its outstanding advantages. This technology creates lightweight slabs, allows for long spans, optimizes material costs, and contributes to environmental protection by minimizing resource wastage. Let’s explore the construction process for Nevo flat slabs through the following steps with BÊ TÔNG SMC!

1. Preparation Work for Nevo Flat Slabs

Before proceeding with pouring concrete for the Nevo flat slab, the following preparatory steps need to be taken:

• Site Survey: Conduct a field survey, measure, and record specific customer requirements.

• Designing the Slab: Based on the collected data, proceed with designing the appropriate slab structure drawing.

• Consultation & Agreement: After completing the design, consult and agree on the construction plan with the customer and sign the contract.

• Handing Over Drawings: Deliver the design drawings to the construction unit and assign technical staff to support and supervise the implementation process.

• Material Preparation: Ensure sufficient materials such as steel, formwork, and concrete, as well as prepare the workforce for construction.

• Transporting Nevo Plastic Boxes: Transport and deliver Nevo plastic boxes to the construction site for installation.

2. Concrete Pouring Process for Nevo Flat Slab

Once the preparation work is completed, the installation and pouring of concrete for Nevo flat slabs will be done in the following steps:

Step 1: Formwork Installation

Install the slab formwork according to technical standards and design requirements.

Step 2: Steel Mesh and Edge Beam Setup

Fabricate the slab steel mesh and the edge beam steel around the slab. Use spacers to ensure the slab’s thickness adheres to the design.

Step 3: Installation of Nevo Plastic Boxes

Install and secure Nevo plastic boxes in the correct positions and required spacing. Use connecting bars to ensure the virtual beam thickness follows the design specifications.

Step 4: Steel Fabrication for the Slab

Fabricate the top steel layer, column top steel, anti-puncture steel, and shear reinforcement steel according to technical instructions.

Step 5: Adding C-Shaped Steel

Install additional C-shaped steel to connect the two layers of slab steel, secure the Nevo boxes, and reduce upward buoyant force during the concrete pour. Clean the surface thoroughly before proceeding.

Step 6: Pouring the First Concrete Layer

Pour the first concrete layer using a boom pump to fill half the gap between the Nevo plastic boxes. Use a vibrator to ensure the concrete fills the slab below.

Step 7: Pouring the Second Concrete Layer

Once the first concrete layer has set but still retains some adhesion, pour the second layer directly on top of the Nevo box lids to minimize buoyant force. Use a surface trowel and vibrator to finish the slab surface.

Step 8: Curing the Concrete

Follow the technical procedure to cure the concrete properly to ensure the quality of the structure.

Step 9: Dismantling the Formwork

After the concrete reaches the required strength, remove the formwork, inspect the quality, and clean the slab surface.

This is the process for constructing Nevo flat slabs to optimize the quality and performance of the building. For detailed consultation, feel free to contact BÊ TÔNG SMC via our hotline for support!
