Aal Imran Housing has recently started producing a new type of Prefabricated Units using Glass Reinforced Cement (GRC) which offers a host of features. The Units are well insulated against Sound and Heat Radiation. In addition, they are resistant to Fire, Water, Humidity and the vagaries of the Desert and Coastal Environment.

GRC has been highly regarded for its physical and chemical characteristics, including its longer durability that competes well with reinforcement, concrete and other materials like Wood, Iron, Aluminum and Gypsum Sheets. We use GRC in combination with Ceramics, Marble and Natural Stone Materials to produce units that are suitable for Housing, Military and Tourist Projects.

This method is classified under category of Light Weight Prefab Building (on a turn-key basis). It is a complete building of one or two floors with traditional finishing.  

Cement Fiber Glass
General Description:

  • Cement Fiber Glass is a material developed from G.R.C with higher mechanical, physical & chemical specifications.

  • Its stresses are 3 times of reinforced concrete and the normal life time is not less than 4 times to that.

  • It is not affected by water and humidity, resists alkalis, acids, salts and sea iodine and insulates the heat.

  • It is very rigid and heavy, high resistance for friction. It can have a smooth anti-pollution surface.

Composition & Manufacturing Methods: 

  • Cement, Sand, Polymers, Water and Adhesive Materials

  • Reinforced by Distributed Alkaline Fiber Net (A.R Fiber) which can bear a heave high tension

  • Exposed to a special mechanical operations during manufacturing to be very right after drying and treatments

A.R Fiber:
A.R. Fiber differs from other fibers in the inclusion of Zirconium Oxide (ZRO2) which provides the Alkaline Sistances property.

The class is melted by electric or gas heated furnaces, molten glass passes from the furnace to series of electrically heated outlets which are made of platinum that defies the high temperature.

A bushing has many hundreds of small nozzles in its base from which the molten glass exudes and is drawn into filament 10-20 um in diameter. The fibers pass through a fine water to freeze. At this stage the fibers are separated as individual filaments.

Uses of the Material: 

  • The material can be used for producing Islamic Moulding and decoration, precasted light domes, hip tiles and a very recent facing of buildings.

  • The material is ideal to resist humidity and bad weathers to perform balcony and entrance and window’s cap.

  • The material can be used for making prefabricated domes for chalets in tourist villages. The dome of 6 Ø has thickness not more than 2.5 cm, so it is light and has low cost and many domes can be constructed in a single day.

Mechanical & Physical Properties: 

  1. Density                                 1.7-2.1 tom/m³

  2. Bending St.(lop)                      7-11 n/mm²

  3. Bending St. (MOR)                   21-31 n/mm²

  4. Tension St. (Bop)                    5-7 n/mm²

  5. Tension St. (UTS)                    8-11 n/mm²

  6. Strain to Failure                       0.6-1.2%

  7. Young’s Models                        10-20 kn/mm²

  8. Impact                                   10-25 n/mm²

  9. Compression                            50-80 n/mm²

  10. Inter-Laminar Shear                  3.5-5 n/mm²

  11. Punch-Through Shear                20-45 n/mm²

  12. Enplane Shear                          8-11 n/mm² 

Prefabricated Buildings System 

Walls: 

  • Sandwich Panels 6 cm thick with Heat & Sound Insulating Core.

  • Panels Bears Two Floors Insulating Life and Dead Loads.

  • Panels are Semi-Finished and have all Electric and Water Embedded Pipes. The Panels are surrounded with special Interlocking made of Wood, Metal or G.R.C which makes it easy for assembling and make the building one strong and rigid block not affected by the Storms & Earthquakes.

Ceilings: 

  • As Walls but with different Thickness depending upon Loads and Span of the Bearing Walls. The ceiling panels are assembled together and also with walls by special Interlocking. The Ceiling which bears another floor will be reinforced by wood, steel or G.R.C Beams.

  • It can be Flat, Beached, Dome, Vaults and Shell Constructions.

Uses of the Prefabricated Building System: 

  • The system serves Housing, Educational, Tourist, Administrative Exhibitions, Industrial and Military Buildings etc.

  • It has a Manner System with Octagonal shape make unlimited number of designs as the children Mecano.

  • There are Caravans upto 40 m² including Bathroom, Kitchen, Water Tank, Drainage Tank and a Generator. It can be moved on wheels or carried by trucks.

  • Due to the light weight (85 kg/m²), more than one floor on the roof of the existing buildings can be made.

  • This system is successfully used by the Pilgrims in Mecca because of its assembling and dissembling features and its insulation of Heat and Non-Flammability.

Features of the System 

  • Complete Isolation of Heat & Sound

  • Non Flammable

  • Never affected by Humidity, Bad Coastal & Desert Weathers

  • Finished by the normal finishing methods as Ceramic Tiles, Marble and Pharaonic Stones etc.

  • Easy to assemble and disassemble, hence save time and resources. Interlocks are used for walls bases and between the walls and ceiling which results the building as one strong rigid block, not to be affected by the heavy storms and earthquake contrary to the other kinds assembled using Bolts/Screw Joints etc.

  • Cost effective, specially in the places far from the Cities

  • Can be built on week soils also

  • One or two additional floors can be installed on the same foundation of an existing building
