JOINTLESS SFRC FLOOR
Designing and pouring jointless floors using Steel Fiber Reinforcement and Laser Screeding Technology is the latest in concrete flooring technology.The word jointless can be misleading because the concrete area has a practical upper limit that can be placed in a single continuous operation. No joints are sawn, but steel fibers incorporated in the concrete mix control the width and distribution of cracks resulting from shrinking.Usually it is not possible to ensure that there are no visible cracks on the ground. Therefore performance criteria should be established with respect to the width and frequency of cracks.
Jointless SFRC floor
The fields are limited and shaped when making joint floors using manufactured special profiles for expansion joints with dowels installed and integrated joint edge protection. The dowels contribute to the transfer of load between the two adjacent fields and allow the joint to be opened up to 30 mm due to shrinking or temperature differences.
By replacing traditional welded mesh reinforcement with high-end structural steel fibers the loading bearing capacity of the floor increases significantly, thus achieving greater control over the cracks. It is possible to make a jointless field of large bay areas because of the steel fibers bridge the cracks that form in the concrete and prevent their further opening into larger cracks.
Advantages of Jointless SFRC Floor
- Less floor thickness compared with that of floors with conventional reinforcement due to the ability of fiber to accept plastic loads
- Reducing the length of joints up to 75%
- Decreased curling of the floor, which means: lower maintenance costs of servicing warehouse equipment (forklift trucks, reach trucks, VNA machines, etc.). the higher
- speed of service equipment, higher productivity of the warehouse activities
- Reduced health complaints from drivers of the servicing warehouse equipment
- Aesthetic appearance on the floor
- Increased dynamic strength and impact resistance
- Less damage to edges and corners.
- Racking and equipment can be placed on the floor anywhere –no traditional considerations
- Reducing chances of compromise joints and related repair activities, which means lower maintenance costs on the floor.
- Excellent fatigue and endurance Shrinkage and crack control Increased tensile strength, compression
- shear flexural strength
- High impact resistance Faster floor construction
