QDVC Interview Questions, Process, and Tips

Waterproofing methods include membrane waterproofing, cementitious waterproofing, crystalline waterproofing, and bituminous waterproofing.

• Membrane waterproofing involves the use of a thin layer of waterproof material, such as rubber or PVC, applied to the surface.

• Cementitious waterproofing uses a cement-based mixture that forms a barrier against water penetration.

• Crystalline waterproofing involves the application of ch...read more

SRC concrete contains supplementary cementitious materials that enhance its durability and resistance to chemical attack.

• SRC stands for Sulphate Resistant Cement

• SRC concrete is specifically designed to resist the damaging effects of sulphate attack

• Non-SRC concrete does not contain any additional materials to enhance its resistance to sulphate attack

• SRC concrete is commonly used in marine structures, wastewater treatmen...read more

Fiber concrete is used to enhance the strength, durability, and crack resistance of concrete structures.

• Fiber concrete improves the tensile strength of concrete, making it more resistant to cracking and shrinkage.

• It enhances the durability of concrete by reducing the permeability and increasing resistance to chemical attack.

• Fiber concrete can be used in various applications such as road pavements, industrial floors, pr...read more

Concrete plasticizer is a chemical admixture used to improve the workability and durability of concrete.

• Concrete plasticizers are added to concrete mixtures to reduce water content and increase flowability.

• They improve the strength and durability of concrete by reducing the amount of water needed for proper hydration.

• Concrete plasticizers can also enhance the workability of concrete, making it easier to pour, place, an...read more
