CHEMICAL RESISTANT BRICK PROPERTIES:

Khodiyar has been manufacturing chemical resistant brick and tiles since 1995, for 2 decades khodiyar has continuous made improvement in quality of brick and tiles manufacturing.

KCIPL owns 3 tunnel kilns and 6 vacuum extrusion machines makes the chemical resistant brick properties superior than other players in india.

KCIPL Chemical Resistant Brick Properties – Specification

  • Khodiyar acid/alkali resistant bricks comply with ASTM C-279 with type II and III specification.
  • It also complies with DIN EN 993-16 and IS 4860 with class I specification where minimum water absorption and maximum acid resistance is required.
