BAUGRC (Glassfiber Reinforced Concrete) is one of the most innovative construction materials available today as it facilitates unprecedented possibilities for on-site assembly, higher resistance to water penetration, cracking, tensile strength, flexural strength, pressure resistance and impact resistance than traditional precastt concrete, altogather with unprecedented opportunities for design.
Versatility, lightweight, incredible strength and durability, investment savings and unlimited diversity in design. These are the advantages BAUGRC provides for the architect/designer.
For the owner and tenant, BAUGRC provides durability, fire resistance, sound attenuation, energy conservation and general superior properties inherent in the material
BAUGRC allows the architect great flexibility in designing the most visible element of the structure – the Façade.
The variety of sculptural shapes made possible through the BAUGRC manufacturing process enables a wide range of creative architectural designs. The degree of such complex shaping has minimal effect on the cost of the end product due to the inherent design flexibility and characteristics.
BAUGRC is ideal for building rehabilitation or renovation projects. It’s light weight minimizes the load added to the existing structure. Its design flexibility in color, texture, pattern and surface finish allows it to blend in with other construction materials.
Exact replicas of the original ornamental work and other historic buildings can be made of BAUGRC.
BAUGRC can be easily produced to match a granite or limestone facing; it can even be made to resemble a metal panel or match ornate terra cotta.
GFRC can be manufactured to faithfully reproduce the look and feel of architectural precast, terra cotta masonry, and a wide variety of natural stone such as granite, sandstone, or limestone at a fraction of the weight and cost of the original materials.
BAUGRC is capable of accepting and transferring wind and self-weight and their own inertial seismic loads to the building’s load resisting system, but are not considered as vertical loadbearing components or as part of the lateral load-resisting system.
Weighing up to 80% less than architectural precast, BAUGRC panels materially reduce the weight and cost of the foundation, footings, and structural framing needed to support multi-story buildings. This enables the owner to reduce overall construction costs and accelerate schedules without sacrificing the durability or the architectural aesthetic of precast concrete fabrication.
GFRC is widely used today for both new building construction and for recladding of existing building facades. In recladding applications, GFRC can often be installed directly over the old cladding with minimal superimposed load on the existing structure, and minimal upset to existing tenants and operations.
GRC is a Portland cement based composite with alkali-resistant glass fibers that are randomly dispersed through-out the product. The fibers serve a purpose similar to the reinforcing steel rebars which is placed primarily in tensile stress areas.
GRC has proven global performance since the alkali-resistant glass fibers were developed in 1969.
The GRC is manufactured by hand – spraying a cement/sand slurry fitted with special additives and admixtures and glass fibers into forms of the desired shape and size. The cement/sand slurry is fed via a pump through a slurry spray gun. Attached to the slurry spray gun is an air-powered chopper gun that cuts the continuous glass fiber strands into approximatively 40 mm (1 ½ inch) long pieces. The chopped fiber strands and the cement/sand slurry are simultaneously propelled onto the form’s surface. Several layers are deposited.
Each layer is compacted with the hand roller until the required shell thickness is reached.
After initial curing, the shell is removed from the form for final curing outside.
Unlike many other exterior wall systems, BAUGRC elements are delivered to the site with steel studs integrated into the exterior shells. This avoids the time and expense of adding the studs later. Further savings can be achieved by using less expensive fastening hardware due to shell’s lighter weight.
Because the glass fibers add flexural, tensile and impact strengths, the resulting material allows the production of string – yet lightweight BAUGRC architectural Prefabricated Wall Shells and Complicated Exterior Decoration, that bear also a layer of thermal insulation that can fit any R or U value requirements.
The insulation layer is mineral wool or PU Foam.
It is important in evaluating costs to realize that BAUGRC Wall Shells provide more than the exterior finish and thermal insulation. The steel frame of the BAUGRC provides a surface for applying the interior finish , such as drywall, as well as the window framings. The usage of the BAUCLAD also saves important interior space as the shells are fixed by the outer perimeter of the floor line.
BAUGRC Prefabricated elements are project specific, are moulded according to engineers’ drawings and are available as wall units, window units, large mouldings, column covers and decoration.
Because BAUGRC is inorganic and does not contain materials that will burn or produce noxious gases, it does not add to the fire load of the building. BAUGRC can be designed to provide various degrees of fire resistance that may be required by building codes, insurance companies and other authorities.
The design of the joints between BAUGRC Wall Shells is an integral part of the total wall design. Requirements for joints are assessed with respect to both performance and cost. Joint width is not chosen for reasons of appearance alone, and is related to shell size, building tolerances, anticipated movement, joint materials, and adjacent surfaces.
The requirement of the joint width is also dictated by the temperature extremes anticipated at the site location, the movement capability of the sealant to be used, shell fabrication size, etc. Minimum joint design is 12mm (1/2 inch) where as 20 mm (3/4 inch) is preferred.
Maintenance and weathering of the panels will depend largely on its surface finish and local atmospheric pollution. The shape and surface features of the shells will dictate the way water drains off and to what degree the shell will be self cleaning. It is a distinct advantage of BAUGRC that architects can choose the shapes, textures and details of the shells to mitigate the effects of weathering.
To assure a consistent uniform manufacturing process, we at BAUGRUP employ strict quality control procedures, such as materials testing, testing during fabrication and testing of the cured composite.
