1. SCOPE

This standard lays down the requirements for classification, general qua]ity,dimensions and physical requirements of pulverized fuel ash-lime bricks used in buildings.

NOTE - Pulverized fuel ash-lime bricks having wet compressive strength less than 30 N/mm2 approximately 300 kgf/cm2 are covered in this standard and for higher strength ( see IS 2180 and IS 1077 ).
