What are the different grades of sealing compounds in IS 1834?

Grade A for normal conditions and Grade B for areas exposed to jet fuel spillage (Clause 3.1).

What is the acceptable penetration range for the sealant?

15 to 50 (in 0.1 mm units) at 25°C, 100g weight for 5 seconds (Table 1).

What is the maximum permissible flow for the sealant at high temperatures?

Maximum 5 mm when tested at 60°C for 5 hours (Table 1).

This standard specifies the physical requirements and testing methods for hot applied sealing compounds used in concrete joints. It classifies sealants into Grade A for normal pavements or structures and Grade B for airfields where resistance to jet fuel spillage is required.

Practical Notes

Avoid heating the sealant beyond the safe heating temperature specified by the manufacturer to prevent polymer or rubber degradation.

Joint faces must be thoroughly cleaned, dried, and properly primed before pouring the sealing compound to ensure adequate adhesion.

Grade B must be explicitly specified for airfield pavements or industrial zones subjected to aviation fuel and lubricant spills.
