Yes, DPC (damp proof course) is required in boundary walls to prevent rising damp.

• DPC is necessary to prevent moisture from rising up through the walls.

• It helps in protecting the structure from dampness and water penetration.

• Common materials used for DPC include bitumen, plastic sheets, and chemical compounds.

• Proper installation of DPC is essential to ensure its effectiveness in preventing dampness.

Shear and bending moment diagrams show the variation of internal forces along a beam.

• Shear diagram shows the variation of shear force along the length of the beam.

• Bending moment diagram shows the variation of bending moment along the length of the beam.

• Shear force changes sign at point of concentrated load or reaction.

• Bending moment is zero at points of concentrated load or reaction.

The grade of steel bar commonly used in construction work varies depending on the specific requirements.

• The most commonly used grade of steel bar in construction work is Fe 415.

• Fe 415 steel bars have a minimum yield strength of 415 N/mm².

• Other grades of steel bars used in construction include Fe 500, Fe 550, and Fe 600.

• Fe 500 steel bars have a minimum yield strength of 500 N/mm².

• Fe 550 steel bars have a minimum yield strength of 550 N/mm².

• Fe 600 steel bars have a minimum yiel...read more

Site plans are detailed drawings that show the layout of a construction site and its surrounding area.

• Site plans provide a visual representation of the proposed development on a piece of land.

• They show the location of buildings, roads, utilities, landscaping, and other features.

• Site plans help ensure that the development complies with zoning regulations and building codes.

• They are used by architects, engineers, and contractors to understand the project and coordinate their wo...read more

Types of foundations include shallow, deep, and special foundations.

• Shallow foundations: spread footings, mat foundations

• Deep foundations: piles, drilled shafts

• Special foundations: caissons, cofferdams

The ratio of M-20 concrete is 1:1.5:3 (cement:sand:aggregate).

• The ratio of M-20 concrete is 1 part cement, 1.5 parts sand, and 3 parts aggregate.

• For example, if you have 1 kg of cement, you will need 1.5 kg of sand and 3 kg of aggregate to make M-20 concrete.

Cement is a binding material used in construction to hold together different materials.

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

• It is mixed with water to form a paste that hardens over time, known as concrete.

• Cement is used in various construction applications such as building foundations, roads, bridges, and dams.

• Different types of cement are available for specific purposes, such as Portland cement, which is commonly used in general ...read more
