RCC VEDA

Why is Steel used as reinforced material in RCC?

• Steel is not reactive to water

• Thermal coefficient of steel is same as that of concrete

• Steel provides compressive strength to the structure

• None

Among the properties of cement, to determine the compressive strength , what should be the face area of cement mortar cube prepared for conducting the compression test (cm² )

• 50

• 15

• 225

• 176

Maximum permissible limit of sulpates in water (mg/l)

• 200

• 3000

• 400

• 500

Yield strength of Fe 250 bar

• 415

• 250

• 500

• None

The yield plateau in mild steel can be avoided by

• Cold working Process

• Strain hardening

• Heating

• Electrolysis

TMT stands for

• Thermo mechanically treated bar

• Total metal toughness

• Thermal Metal Toughening

• Toughened Mechanised Technology

The inner core of TMT bars is:

• Brittle

• Soft and ductile

• Rigid

• Fully quenched

What is the full form of RCC in construction?

• Reinforced Cement Concrete

• Ready-mixed Concrete Composite

• Rolled Compacted Concrete

• Reinforced Coarse Cement

The term “reinforced” in RCC refers to:

• The use of admixtures

• Addition of steel bars

• Extra thickness of concrete

• Post-curing techniques

Which type of water is suitable for mixing concrete?

• Acidic water

• Softened water

• Drinking-quality potable water

• Industrial wastewater
