Siporex Fluted Wall Panels Size 600*300 mm width 200 mm

Technical Details

Various international codes and standards had been developed to provide engineers and designers with provisions for the analysis and design of AAC factory-produced blocks and reinforced panels based on various research studies and experiences on Its use.

These include guidelines or recommended practices addressing the materials, manufacture, and structural design of AAC including design considerations such as erection and construction details incorporating the use of AAC products in conventional construction. Some of these Codes & Standards are listed below:

Lightweight

SIPOREX weighs less than a quarter compared to conventional concrete. Due to the lightweight property of SIPOREX, the foundation loads are greatly reduced resulting in big savings in the overall construction cost, especially in areas having poor soil-bearing capacity. Its lightweight also means a significant advantage in transportation costs.

Energy Efficient

SIPOREX ensures pleasantly healthy and comfortable room temperature without the need for additional insulation. Its thermal insulation and heat retention offer good protection against rapid cooling or heating up too much. This means lower power consumption in the environmental management system.

Dimension Accuracy

The production process guarantees the accurate dimensions of the panels and blocks that comprise the building system. This allows for straight and plumbed walls resulting in less on-site trimmings and reduces the quantity of mortar and finishing materials required. The dimensional tolerance is ±3mm for thickness & width and ±5mm for length.

Workability

SIPOREX products can be sawn, cut, slot, drilled, chased, and nailed with ordinary woodworking tools which makes them easier to install than other building materials. This also simplifies the installation of electro-mechanical services and other utilities, which means more cost savings.

Resistant to Fire

SIPOREX is totally inorganic and does not contain any combustible materials, which means it is resistant to fire. A 15 cm thick panel will resist fire for seven life-saving hours. SIPOREX product complies with the Saudi Building Code thermal requirements with a very low U-value of ≤ 0.34 W/m2.K. SIPOREX is ideal for firewall applications and as protection for structural steel construction.

Acoustic

Insulation SIPOREX meets the appropriate standards for sound insulation in house buildings, which means a quieter and more comfortable interior. In industrial construction, SIPOREX minimizes industrial noise pollution. The sound absorption of untreated SIPOREX surfaces is better than that of dense concrete.

Non-Toxic

SIPOREX itself is ecologically harmless, since it neither contains gases nor fibers, it is neither dangerous to ground- water nor does it releases any radioactive radiation. No pollutants or toxic by-products are produced in the manufacturing process or even when subjected to fire.

Durability

SIPOREX products do not contain any organic matter subject to deterioration and will not degrade even under severe weather conditions. Structures built several decades ago are still in active use today.

Quake Resistant

The low mass of Siporex results in a reduced total dead load of the building and consequently reduces the applied seismic forces to its structure. Structures built in earthquake zones such as Japan & Mexico have shown good resistance to seismic forces in actual practice.

Speedy Construction

SIPOREX has all the advantages of a precast system, i.e. eliminates shuttering, wet construction, curing, on-site testing & quality control resulting in reduced overall construction time and cost. It also requires minimal supervision and construction staff.

Pest Resistant

SIPOREX provides an airtight interior, does not contain any organic ingredients,s and makes your home uninviting to pests, insects, or rodents.

Strength

In relation to its dry density, SIPOREX can withstand relatively high compressive stress, which in the aspect of the application is very sufficient to take building loads. SIPOREX achieves its full strength during the autoclaving process. The minimum compressive strength is about 35 kg/cm2 for a nominal dry density of 550 kg/m3.

Structural System

Siporex buildings are designed based on the box system principle. Siporex load-bearing walls act as shear walls resisting lateral forces due to wind or seismic loads. The wall panels have grooves along their edges which form joints when erected. These joints receive steel tie bars from the footing and at the top connecting the lower wall with the one above. As they penetrate the ring beam, a strong connection will be provided between the vertical and horizontal structures. These joints (3.3 × 5 cm) are grouted and they are able to transfer shear forces from one panel to the other.

The roof and floor slabs have tongue and groove as well as a notch at the top to be reinforced with an 8mm diameter bar between spans and grouted with cement-sand mortar (1:3) consequently eliminating differential deflection. Due to the ring and bond beams around the building, all slabs form membranes acting as laterally stiff diaphragms which can transfer lateral forces to the bearing walls.

These constitute the diaphragm action of the Siporex structural system. Lateral forces are distributed in proportion to the moment of inertia of the walls, that is, proportional to their stiffness. Based on actual experiences of actual occurrences in different countries, It has been noted that Siporex buildings are very resistant to earthquake forces.

Design Principle

Much of the company's work entails the conversion of the client's original designs from other materials to Siporex system, generally resulting in cost and energy savings. But the best and most economical use of Siporex is produced by designing the material from the onset.

Optimum results and savings can be obtained through careful design work and meticulous planning before and during execution. Before commencing the architectural design for a project, the following guidelines should be noted:

• The maximum span of Siporex panels is 6.00 meters. This means that the maximum clear span between the load-bearing walls should not exceed 5.85 meters considering the 75 cm end bearing of floor/roof slabs. The distance between the non-load-bearing walls is immaterial. If the clear span is more than 5.85 meters, then steel or concrete beams supported on steel or concrete columns should be used to support the roof slabs.
• The upper walls are recommended to be aligned with the walls of the lower floor. Walls on the upper floor supported directly on Siporex slabs are not allowed. When unsupported walls cannot be avoided, intermediate steel beams can be used or convert the wall to a non-load bearing lightweight drywall partition, in order to achieve maximum economy.

• The foundation should be made high enough such that the external wall panels will not absorb moisture from the ground.
• The width of door/window openings is recommended to be limited to the allowable spans shown in Sections 4.2.4 & 4.2.5 in order to utilize Siporex lintels and avoid the use of in-situ concrete lintels.
