Legend:

• VI = Very Important
• I = Important
• R = Required
• D = Desirable
• 1 = Some degree
• 0 = Variable

Additional Notes:

• Maintenance (Clause 5.7): Flooring should allow easy maintenance and repair to restore original condition.
• Structural Stability: Floor finish performance depends on the structural floor's strength and stability; movement or chemical spillage can cause failure.

Practical Tip:

Choose floor finishes based on the most critical requirement (abrasion, chemical resistance, slip resistance) for your industry type, balancing cost and durability.

IS 4971: Cement Concrete and Stone Flooring - Key Points

1. Plain Cement Concrete (Clause 6.1.1)

• Used widely for industrial floors.
• Resistant to mineral oils and greases; slowly attacked by acids, vegetable oils, fats, sugars.
• Properties (Table 2):

VG = Very Good, G = Good, P = Poor

2. Bedding and Jointing Materials (Clause 8.1.1 & Table 5)

• Must adhere well, be durable, and resist chemical attacks.
• Materials include:

• Bedding and jointing can be different; chemical-resistant mortar recommended for joints in severe exposure.

3. Recommended Finishes for Dairy Floors (Table 4)

• Heavy impact: Steel tiles embedded in granolithic concrete.
• Wet and chemical exposure: Paving bricks or chemical-resistant resin mortar joints.
• Cold storage: Acid-resistant bricks or tiles embedded in cement mortar with resin joints.

4. Stone Flooring (Clause 6.3)

• Use natural stones with good abrasion and chemical resistance.
• Should be laid on a proper bedding mortar and jointed suitably.
