Qualtech Engineers Assistant Engineer - Civil Interview Questions and Answers

Curing is the process of maintaining moisture and temperature conditions for freshly placed concrete to promote its hydration and strength gain.

• Curing is essential for the strength and durability of concrete.

• It involves keeping the concrete moist and at a proper temperature for a specific period of time.

• Curing can be done using various methods such as water curing, membrane curing, and steam curing.

• The duration of curi...read more

The strength of cement depends on its grade and type.

• The strength of cement is measured in terms of compressive strength.

• The grade of cement determines its strength. Higher the grade, higher the strength.

• Type of cement also affects its strength. For example, Portland cement has higher strength than lime cement.

• The strength of cement is also influenced by factors such as curing time, temperature, and humidity.

The block shear strength in the bolt connection shown in fig 28 is dlong.

• Block shear strength refers to the maximum load a bolt connection can withstand before failure.

• The term 'dlong' likely refers to a specific value or calculation related to the block shear strength.

• To determine the block shear strength, factors such as the material properties, bolt size, and connection design must be considered.

• Examples of factors ...read more

The bearing capacity of a bolt is a measure of its ability to withstand loads without failure.

• Bearing capacity is influenced by factors such as bolt diameter, material strength, and surface conditions.

• The bearing capacity can be calculated using various formulas, such as the Euler's formula or the Goodman's formula.

• For example, the bearing capacity of a bolt can be determined using the formula: P = A * σ * F

• Where P is ...read more

The size of a rivet is determined by its intended use and the structural requirements of the application.

• The size of a rivet is determined by the load it needs to bear.

• The size of a rivet is also influenced by the thickness and material of the materials being joined.

• Factors such as shear strength, tensile strength, and grip range are considered when determining the size of a rivet.

• For example, in heavy structural appli...read more
