Abstract

The present paper deals with the treatment of Bambusa tulda with ten different fire retardant-cum-preservative compositions to offer protection against fire. The performance of treated bamboo against fire was tested for flame penetration, inflammability and rate of burning test as per Indian standards. Bambusa tulda treated with only four compositions passed all fire retardant tests.

Abstract

Bamboos are versatile material for countless applications. Their wider use for construction is encouraged because of growing scarcity of timbers. Since it has a very low natural durability, protection against biological degradation is of vital importance for long-term services. Protective measures without chemicals are preferable, but often limited in their effectiveness. For using preservatives, the restricted permeability of culms tissue, choice of preservative and treatment method and environmental effects as well as economical aspects have to be considered. Treatment of Dendrocalamus strictus and Bambusa nutans in green round form with holes revealed higher retentions of copper-chrome-arsenic (CCA) than bamboo without holes by Alternate pressure method. Lower retentions were recorded in both the species treated by full cell process.
