Dharamraj Construction Interview Questions and Answers

Types of beams include simply supported, cantilever, continuous, and fixed beams.

• Simply supported beams are supported at both ends and have no restraint at the supports.

• Cantilever beams are supported at one end and have no support at the other end.

• Continuous beams have more than two supports and are capable of transferring moments.

• Fixed beams are supported at both ends and are capable of transferring moments and shear ...read more

The density of steel is approximately 7.85 grams per cubic centimeter.

• Density of steel is a measure of how much mass is contained in a given volume of steel.

• It is commonly expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

• The density of steel can vary depending on its composition and specific type.

• For example, the density of carbon steel is around 7.85 g/cm³, while stainless steel has...read more

An estimate is a calculated approximation of the cost, time, or quantity of a project or task.

• An estimate is used to determine the approximate cost, duration, or quantity of materials required for a project.

• It is based on available information, historical data, and expert judgment.

• Estimates are essential for budgeting, planning, and decision-making in construction projects.

• Estimates can be prepared for various aspects ...read more

The largest scale in civil engineering is the macro scale, while the smallest scale is the micro scale.

• The largest scale in civil engineering is used to study large structures and systems, such as bridges, highways, and dams.

• The smallest scale in civil engineering is used to study the behavior of materials and components at a microscopic level.

• Examples of the largest scale include designing a city's transportation netw...read more

Cement is a binding material used in construction to hold together different components of concrete.

• Cement is a fine powder made from a mixture of limestone, clay, and other minerals.

• It reacts with water to form a paste that hardens and binds the aggregates together.

• It is a key ingredient in the production of concrete, mortar, and grout.

• Different types of cement are available for specific construction purposes, such as...read more

Water cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix.

• Water cement ratio determines the strength and workability of the concrete.

• A lower water cement ratio results in stronger and more durable concrete.

• The water cement ratio should be carefully controlled to achieve the desired properties of the concrete.

• For example, a water cement ratio of 0.5 means that for every 1 kg o...read more

The weight of steel can be calculated using the formula: weight = volume x density.

• Calculate the volume of the steel component using appropriate geometric formulas.

• Determine the density of the specific type of steel being used.

• Multiply the volume by the density to obtain the weight of the steel.

• For example, to calculate the weight of a steel beam, you would measure its dimensions and use the formula: weight = volume x ...read more

WMM stands for Wet Mix Macadam and WBM stands for Water Bound Macadam.

• WMM is a type of road construction method where aggregates are mixed with water to form a base course.

• WBM is a type of road construction method where aggregates are bound together with water and compacted to form a base course.

• WMM is commonly used for highways and heavy traffic roads.

• WBM is commonly used for low-traffic roads and rural areas.

• WMM prov...read more
