Compressive Strength Test

Combining various kinds of fibre to achieve good response and strength from the concrete by using different experiments is shown in this research. Here PVA which is polyvinyl alcohol and HS hooked end steel fibres are used to gain more strength compared with normal concrete or single fibre concrete. Here first we take PVA specimens results by considering optimum dosage 0.15% result & HS fibre is taken as HFRC concrete by this the strength of the concrete can control the crack behavior occurred in specimens. Mechanical properties such as compressive strength test, flexure strength, and stress-strain behavior are studied. Combining different fibers HFRC is mainly useful for longstanding structures. This method can be easy to understand and economical.

Micro Level

The high strength concrete exhibits improved compressive strength with drawback of brittle failure due to lack of tensile strength which can be catered by the addition of fibers. The efficient use of fibers with hybridization at macro and micro level can improve mechanical properties of high strength concrete. The effect of hybridization of hooked end steel macro fibers (60 mm) and PVA micro fibers (12 mm) with different dosages was investigated in this research work. The different percentage of steel and PVA were hybridized to find out the best combination of hybridized fibers in high strength concrete. The compressive and flexural properties of high strength concrete along with complete load vs deflection behaviour of hybrid fiber reinforced concrete were investigated. The results revealed that hybridization of macro and micro fibers provided better improvement in flexural performance. It was observed from the results that the hybrid combination of fibers of 1% macro steel fiber and 0.15% micro PVA fibers proved to be the best for enhancement in flexural performance of high strength concrete.

Shaft Lining

In order to solve the problem of highly brittle shaft lining under dynamic loading, a combination of hybrid fiber concrete mixed with steel and polypropylene fiber is proposed to make shaft lining. C60, the concrete commonly used in shaft lining, was selected as the reference group. The static mechanical properties, dynamic mechanical properties, and crack failure characteristics of the hybrid fiber concrete were experimentally studied. The test results showed that compared to the reference group concrete, the compressive strength of the hybrid fiber-reinforced concrete did not significantly increase, but the splitting tensile strength increased by 60.4%. The split Hopkinson compression bar results showed that the optimal group peak stress and peak strain of the hybrid fiber concrete increased by 58.2% and 79.2%, respectively, and the dynamic toughness increased by 68.1%. The strain distribution before visible cracks was analyzed by the DIC technology. The results showed that the strain dispersion phenomenon of the fiber-reinforced concrete specimen was stronger than that of the reference group concrete. By comparing the crack failure forms of the specimens, it was found that compared to the reference group concrete, the fiber-reinforced concrete specimens showed the characteristics of continuous and slow ductile failure. The above results suggest that HFRC has significantly high dynamic splitting tensile strength and compressive deformation capacity, as well as a certain anti-disturbance effect. It is an excellent construction material for deep mines under complex working conditions.

The main objective of the fibre glass in concrete roof tile is to obtain good strength, heat resistant, & water seepage resistant roof tile. To ensure that the roof tile produced plays a role development with minimum cost, and high flexure strength. To draw an analogy between the normal concrete roof tile with glass fibre concrete roof tile. The sizes of short fibres used were 25mm and the glass fibres were alkali resistant. The effect of these short fibres on wet transverse strength, compressive strength and water absorption was carried out.
