Glass fiber reinforced concrete (GFRC) is a cementitious, composite material, cast in thin shell shapes for use in construction consisting of Portland cement, aggregate, water, alkali-­‐resistant glass fibers, polymer and additives. GFRC can be used wherever a light, strong, weather resistant, attractive and fire retardant material is required.

There are four primary categories for fiber-reinforced concrete based on the material used to produce the fiber. Type I: Steel Fiber-Reinforced Concrete- stainless steel, alloy steel, or carbon steel fibers conforming to ASTM A820. Type II: Glass Fiber-Reinforced Concrete- alkali-resistant glass fibers in accordance with ASTM C1666.

Concrete and reinforced concrete are the two most commonly used construction materials in the world. In reinforced steel, the compressive stress is usually taken on by the concrete, since it resists compression well. However, its tensile strength is low, therefore steel reinforcing bars are placed where tensile stress occurs in the construction.

 · The goal of this project is to achieve high energy and construction efficiency through additive manufacturing (i.e., 3D ) of concrete walls in buildings. 3D concrete possesses new opportunities for advancing energy efficiency and manufacturing in building construction, with demonstrated savings in construction cost and time.

 · In short, reinforcement in concrete gives it the ability to withstand bending, to span across spaces as a beam instead of an arch, and it gives a smaller volume of concrete the ability to do more – to span further and withstand greater loads. Reinforced concrete is used in all types of construction projects, from the smallest domestic builds ...

 · Reinforced Concrete Prefabricated Ready Foundation Sockets, The pre-fabrication of prefabricated foundation sockets offers economic advantages in the field in terms of workmanship and installation. In addition, since concrete curing is carried out during manufacturing in our factory, the size and quality of the concrete can be made more precisely.

 · Textile Reinforced Concrete: Slim concrete components with enormous load-bearing capacity, low weight and high durability even under extreme environmental conditions. Textile reinforced concrete offers these opportunities. This can make an important contribution to sustainable construction: Slim components mean less building material required ...

 · Reinforced concrete was invented during the second half of the 19 th Century. Besides the need to substitute wood for gardening and recreational use, the main driver was the need for an economic and fireproof building material. The development of modern cement and steel during the first half of the 19 th century made this invention possible.

Disadvantages of reinforced cement concrete: The tensile strength of this concrete is 1/10 of its compressive strength. The price of this concrete used for casting is comparatively excessive. The RCC column section is larger than the metal section for multi-story construction. Due to the shrinkage, the crack increases and the strength decreases.
