Jio Interview Questions, Process, and Tips

Mix design is the process of determining the proportions of ingredients in a concrete mixture to achieve the desired properties.

• Mix design involves selecting the type and proportion of cement, aggregates, water, and admixtures.

• It considers factors such as strength, workability, durability, and economy.

• The design is based on laboratory testing and analysis of materials.

• Example: A mix design for a high-strength concrete ...read more

The gauge of binding wire refers to its thickness or diameter.

• The gauge of binding wire is determined by its diameter.

• It is commonly measured using the American Wire Gauge (AWG) system.

• Thicker wires have lower gauge numbers, while thinner wires have higher gauge numbers.

• For example, a binding wire with a gauge of 16 is thicker than a wire with a gauge of 22.

The water-cement ratio (w/c) of M20 grade concrete is typically 0.45.

• The w/c ratio is the ratio of the weight of water to the weight of cement in a concrete mix.

• For M20 grade concrete, the w/c ratio is generally recommended to be 0.45.

• This means that for every 1 kg of cement, 0.45 kg of water is used.

• The w/c ratio affects the strength, workability, and durability of the concrete mix.

Fiber system works by transmitting data through optical fibers using light signals.

• Data is converted into light signals by a transmitter and sent through the fiber optic cable.

• The light signals travel through the cable and are received by a receiver at the other end.

• The receiver then converts the light signals back into data.

• Fiber optic cables are made of glass or plastic and can transmit data over long distances witho...read more

Losses in fiber transmission include attenuation, dispersion, and bending losses.

• Attenuation is the reduction in signal strength as it travels through the fiber.

• Dispersion is the spreading of the signal over time and distance.

• Bending losses occur when the fiber is bent too sharply, causing light to leak out.

• Major fiber optic tools include fusion splicers, OTDRs, and power meters.

• Fusion splicers are used to join two fib...read more
