Steel consumption for overhead tanks varies based on capacity, design, and material thickness.

• Steel consumption increases with larger tank capacities

• Thicker steel material will require more consumption

• Design factors such as reinforcements also impact steel usage

Grade of steel and cement refers to the quality and strength of the materials used in construction projects.

• Grade of steel is determined by its chemical composition and physical properties, such as yield strength and tensile strength.

• Common grades of steel used in construction include ASTM A36, ASTM A572, and ASTM A992.

• Grade of cement refers to its compressive strength and fineness.

• Common grades of cement used in const...read more

Ductile Iron (DI) pipes are a type of iron pipe known for their high strength and durability.

• DI pipes are made from ductile iron, which is a type of cast iron that has been treated while molten to change its carbon content, resulting in a more flexible and less brittle material.

• They are commonly used for water and sewage transportation due to their corrosion resistance and ability to withstand high pressure.

• DI pipes co...read more

Water treatment plant process involves multiple steps to remove impurities and make water safe for consumption.

• Coagulation and flocculation to remove suspended particles

• Sedimentation to settle out floc

• Filtration to remove remaining particles

• Disinfection with chlorine or other chemicals to kill bacteria and viruses

• pH adjustment to ensure water is not too acidic or basic

Chlorination is a water treatment process that involves adding chlorine to water to disinfect it.

• Chlorination is commonly used in water treatment plants to kill bacteria and other harmful microorganisms

• There are different types of chlorination methods such as gas chlorination, liquid chlorination, and tablet chlorination

• Gas chlorination involves adding chlorine gas directly into the water supply

• Liquid chlorination invo...read more

Flexible pavement and rigid pavement are two types of pavements used in different types of road projects.

• Flexible pavement is made of multiple layers of materials that can flex under traffic loads.

• Rigid pavement is made of a single layer of concrete or asphalt that is rigid and does not flex.

• New projects involve constructing roads from scratch, while realignment projects involve changing the alignment of existing roads...read more

The question describes the application of prime coat and tack coat on a WMM surface.

• Prime coat is a low viscous cut back bitumen used to fill up pores and voids on a WMM surface.

• Tack coat is a light application of bitumen, asphalt, emulsion, or dilute water applied on the prime coat.

• The purpose of the prime coat is to bond the WMM surface with the subsequent layers of asphalt.

• The tack coat helps in providing a strong b...read more
