price of filler slab tiles+Wholesale and cheap packaging specifications
The price for filler slab varies depending on how you design them or what you use them for because the materials that are available for filler slabs are tiles, bricks, cellular, concrete, jars and bottles.
filler slab tiles
Filler slabs are a kind of slab building technique that replaces a portion of the concrete at the bottom of the slab with filler material.
Compared to reinforced cement concrete slabs, filler slabs use far less concrete and steel than those slabs. The filler slab is an efficient and cost-effective roofing method based on the roof's concrete parts. This is done in lieu of inserting filler material there.
In comparison to the traditional RCC slab, the filler slab utilizes a lower quantity of concrete and steel due to the use of low-cost and less-heavy filler materials. Some examples of these materials are clay pots, rejected Cali-cut tiles, and shattered bits of cement blocks.
Bricks, cellular concrete blocks, and tiles are some of the materials that can be used as a replacement for the filler slab. The filler slab is primarily based on the principle that for simply supported roofs, the lower part of the slab experiences tensile forces while the upper part of the slab is subjected to compressive forces.
Because of the tensile force, steel is the material that bears the load; concrete, on the other hand, is very good at withstanding compressive forces; consequently, the lower tensile region of the slab does not require any concrete except for the purpose of holding the steel reinforcements together.
Filler slabs have many advantages, such as the consumption of less concrete and steel and a reduction in the overall weight of the slab.
In addition, the use of a filler material that is lighter and less expensive has been introduced. The increased thermal comfort inside the building is a result of the filler materials' heat-resistant qualities and the gap between two of the burnt clay tiles. It results in less need for concrete, as well as a savings of approximately 40% in cement and steel.
Available materials for the filler slab
The following list of available materials for the filler slab is as follows:
- Bricks
- Tiles
- Cellular
- Concrete
- Blocks
- Jars and bottles
These materials are set down in the grids formed by the steel reinforcing rods, and then concrete topping or concreting is performed on top of them.
MATERIAL SELECTION AS PER DESIGN & NEED:
Regarding the selection of the material for the filler slab, the following considerations need to be borne in mind:
It is expected that the filler material will not react with the concrete or steel used in the construction of the RCC slab and that it will be inert in its natural state.
Because it will soak up the hydration water from the concrete, the water absorption rate of the filler materials needs to be checked.
Filler material ought to be lightweight to minimize its impact on the foundations' capacity to support the dead load and optimize the slab's overall density.
Since the cost of the filler material is significantly lower than the cost of the concrete that it is meant to replace, filler material ought to have a low cost.
In order to avoid creating an unsightly ceiling pattern with the filler material, the finish requirements for the ceiling should closely match its texture.
BENEFITS OF FILLER SLAB:
The filler slab has a number of advantages, including but not limited to the following:
STRENGTH:
Conventional tests have proven the load-bearing capacity of filler slabs and found it to be no less effective than other materials.
A variety of institutions and laboratories conducted these tests. Because the filler roof tiles are firmly bonded to one another and covered in concrete, they do not cave in under the impact like coconuts would if they were dropped on the roof.
LEAK PROOFING:
Leaks may be avoided with careful supervision and craftsmanship, and much as in a normal RCC slab, the likelihood of a leak occurring in a filler slab is high. However, leaks can be prevented.
COST SAVINGS:
The potential cost savings range from 15% to 25%; however, in order to design a filler slab and calculate the distance between the reinforcing bars, the services of a structural engineer are required.
THERMAL INSULATION:
It provides a great thermal insulation layer owing to the air pocket that is generated by the shapes of the tiles. Taking into consideration the negative zones and reinforcing regions, the design integrity of a filler slab requires careful planning for such a slab.
PATTERNED CEILINGS:
In most houses, the filler material is left open without plastering in order to form aesthetic design symmetry and to provide aesthetically pleasing patterned ceilings. However, some residents prefer to cover the space with plaster of Paris coating, which also gives good and pleasing ceilings.

How to design filler slab
Before addressing the subject of "how to design a filler slab," it is important to understand that, if properly designed and built, a filler slab has the potential to be a highly inventive, cost-effective, and easy construction technique for slab building.
As the name implies, filler materials are used in filler slabs to replace some of the concrete in the stress zone at the bottom of the slab.
Clay pots and Mangalore tiles have traditionally been used as fillers. Glass bottles, coconut shells, and broken bits of cement blocks are also sometimes utilized.
Recently, I saw an architect filling a media room with broken computer keyboards. Any cyber waste may be employed as long as it is visually appealing.
Sometimes customers just consider aesthetics when selecting filler, giving local availability little consideration. If not, the filler materials are often less expensive.
The utilization of local resources, together with less concrete use, is what makes the project cost-effective. Filler slabs were formerly quite affordable.
We can no longer always claim it is economical. Numerous variables affect it. Filler slabs use less concrete and steel than reinforced concrete slabs. So, depending on the filler you choose, this is undoubtedly greener.
The filler's use in structural principles.
As is well known, the neutral axis experiences compression on top and tensile pressures in the bottom portion for a simply supported RCC slab or any flexural element.
We also know that rebars absorb all tensional forces since concrete is not very good at holding tension. In fact, if the concrete hadn't been fluid, we could have removed it as we were laying it. Since it is a fluid material, concrete cannot be replaced without an efficient method.
Filler materials serve as a mechanism by which we may remove the concrete from the slab's bottom face, where just rebar is required.
Please take notice that in order to guarantee the correct binding and holding of the rebars throughout the design and construction stages, as well as that strength, serviceability, and durability, are not jeopardized in any way, suitable protection for the rebars will be required.
In a different blog post here, you may learn more about the tensile zone in a flexural member.
Even the provision of sleeves in beams is based on the same principle of avoiding compressive zones.
India's filler slab history
In various versions, filler slab technology has been employed for a very long time in India.
This filler slab method has gained popularity in India, notably in Kerala and South India, thanks to Indo-British architect Ar. Laurie Baker.
Back then, it was so well-liked in Kerala that there was a time when everyone yearned to construct a "Baker model house." His fashion was distinctive and ground-breaking.
He was a brilliant architect who included sustainable architecture and green buildings in his designs as early as the 1960s.
His main interests were in the concepts of rainwater collection, reducing the use of materials that need a lot of energy, and creating dwellings that fit their surroundings.
The benefits of filler slabs
The dead load of the slab is significantly decreased as a result of the substitution of nonfunctional cement concrete with lighter filler materials.
Additionally, this aids in lowering the amount of steel needed for structural components and foundations. The weight loss of up to 20 to 30 percent.
Many people overlook the crucial fact that reducing dead weight has a favorable impact on compounds over time. The seismic demand likewise decreases as the dead weight does.
Keep in mind that all seismic force is merely inertia. Learn more about this by watching the video on this blog.
Due to the use of less expensive filler materials and a reduction in the quantity of steel and concrete, it is more affordable by at least 20% when compared to the traditional RCC slab.

If planned and built with strict quality control, filler slabs do not sacrifice strength or longevity.
Living rooms are kept at a pleasant temperature thanks to filler slabs since the air spaces between the filler materials are heat-resistant. In humid, hot climates, infill slabs are a great alternative because of their thermal comfort.
By default, waste management occurs when materials like keypads and scrap plastic, particularly bottles, are utilized as fillers. This is because substances that would otherwise be hazardous to the land and environment are being reused.
A building's carbon footprint is reduced by around 20% thanks to filler slabs. Carefully picked patterns improve the aesthetics of the ceiling in the infill slabs.
The shortcomings of filler slabs
The technique for infill slabs requires some practice. There is a potential that you will make a mistake in the building process unless we have personnel who have constructed a few identical houses.
If the rebars come into contact with filler goods made of clay, they may corrode. To guarantee enough cover for reinforcement, considerable attention should be exercised.
The terrace's slopes must be carefully designed for the same reasons as above, and all rainwater downpipes must be clog-free. Sufficient care must be taken to guarantee terrace upkeep.
standard filler materials and filler material selection criteria
Filler materials should not react with other materials like rebars, cement, or water.
The filler's dimensions, size, and form must match the reinforcement's spacing. All parties involved must coordinate this properly, including the customer, the architect, and the structural engineer. Any last-minute discovery might really lead to a compromise, resulting in rusted rebars and leaks over time.
It is necessary to make sure that the filler only absorbs a small amount of water, and it is best to verify this before construction.
In order to keep prices in check, local materials should be utilized. Lightweight materials should be used.
The choice of materials is also influenced by the design of the ceiling and the room's intended use. For instance, we cannot suggest placing a keyboard in a dining area. However, a media room is ideal for using a keyboard as filler.
Filler Planning and casting for slabs
Filler slabs are cast on-site like regular slabs. The specified rebars are placed, and formwork is laid. Typically, a maximum permitted spacing of 300 or 3d is used. Steel must be supplied in the minimum amount required by codes.
We can use larger spacings than 3d or 300 if a higher quality of control can be offered and if crack widths can be monitored by design. If the size of the material requires greater spacing than 300, then this can be necessary. See the blog's video for additional details.
Be aware that if the filler material is anything that absorbs water, it should be soaked in water before use to prevent it from absorbing moisture from the concrete during construction.
Analysis and Filler Slab Design
The load computation, distribution, analysis, and structural design of filler slabs used in short spans should not vary much from those of a typical slab. To profit from the lighter weight, correct load estimates are required.
It is necessary to refine even live loads. For additional information on how to improve Live loading, see this post on the Civil blog. Design the slab as a typical solid slab depending on whether it is one way or two ways.
The moment coefficients may be adopted from IS-456 based on the edge circumstances. Meeting the L/d ratios may satisfy deflections.
Watch the video for additional information. Additionally, learn more about redistribution to comprehend what occurs if the slab is seen as only supported.
Conclusion
You may have understood Filler slabs and their design after reading this blog. We may construct eco-friendly houses using a variety of simple alternative technologies.
Some older technologies could need some improvement to meet modern needs. To enhance these current methods, it is crucial to understand these principles.
