EXPERIMENTAL AND ANALYTICAL INVESTIGATION ON STRENGTH CHARACTERISTICS OF RIGID PAVEMENT BY USING GLASS FIBRES AND ITS OPTIMUM DOSAGE Revangouda Patil1 1 MTech Student Civil Engineering Dept. Jain college of engineering Belagavi, Karnataka, India ---------------------------------------------------------------------***---------------------------------------------------------------------
Abstract - Due to the high amount of alkali glass Fibers,
4) Tough materials also save shipping costs, allow for design flexibility, and have a lower environmental impact[2].
GFRC gains strength. The GFRC strength under compressive loads is great due to the high content of cement and low w/c (water to cement) ratio. Additionally, these materials have excellent tensile and flexural strength. The efficiency of a Fiber's load resistance depends on its orientation. To provide the necessary tensile strength, the Fiber must be stiff. As a result, these materials perform better than regular concrete. Tensile loads are supported by the high Fiber content, while the polymers in the concrete give it flexibility. GFRC has superior physical characteristics to unreinforced concrete. The strength of steel reinforced concrete is significantly increased by properly constructed steel goods that are made with GFRC or regular concrete)
5) Greater strength increases resistance to earthquake loads 6) GFRC is more resistant to freeze-thaw conditions than regular concrete and is less susceptible to the impacts of the weather. 7) Highly chemical-resistant, anti-corrosive, high flexural, impact, and tensile strength 8) Increase effect defense
Key Words: GFRC, Fibre reinforced, Concrete roads, etc.
9) Strengthen resistance to shrinking of plastic during curing.
1. INTRODUCTION
1.2 GFRC DISADVANTAGES
The pavement construction must be able to provide a surface with a better riding quality, better or enough skid resistance, good light reflecting properties, and less sound. The final goal is to guarantee that the transmitted stresses brought on the wheel load are adequately reduced to prevent them from exceeding the subgrade's bearing capacity. In general, rigid pavements and flexible pavements are both acknowledged as providing this function. The varieties of pavement, their layers, their purposes, and pavement failures are all described in this chapter. Pavements that are improperly designed degrade sooner and have lower riding quality.
No ductility exists.
The capacity of a solid material to deform under stress is known as ductility.
More costlier than conventional concrete.
The challenging is to self-mix GFRC. This kind of concrete is typically mixed, poured, or sprayed by a contractor.
Although the mixture is quite adaptable, if it is not applied or poured properly, it can crumble.

2) Since GFRC is internally reinforced, additional types of reinforcement that could be challenging for intricate moulds are not required[1]. 3) GFRC is made of substances that are unlikely to catch fire. When exposed to fire, the concrete acts as a thermal regulator, shielding the materials from the heat of the flame.
