Glass Fiber
Glass fibers have an affinity for cementitious composites, high tensile strength and modulus of elasticity, are an ideal reinforcement for concrete, and are efficient at very early stages of the cracking process. Moreover, glass fiber density is similar to concrete, which allows a quick dispersion for very short mixing times, with minimum clumping risk and exceptionally low influence on workability. There are typically two major kinds of Glass Fibers:
- Micro fibers control cracking processes that can take place during the entire life-span of concrete. From cracks due tovolume changes in fresh (settlement and plastic shrinkage) and hardened states (thermal and drying shrinkage), to postcrack load-bearing capacity contribution, micro fibers take care of everything. .
- Macro Fibers provide a higher peak strength than plain concrete, due to the total bond between fiber and matrix, which allows the contribution of the fiber action even before the peak load, at the very beginning of the microcracking process. Subsequently, it provides residual strength over a large range of crack openings.
BGSB offers structural software support to design glass fiber reinforced concrete floors. Our design input program collects all necessary project details, and processes them through a finite element analysis plus non-linear fracture mechanics database.The final design report includes the fiber content versus ultimate load relationship for different slab thicknesses, and theircorresponding project requirements.
