Abstract
The double salt calcium phosphateβcalcium sulphate monohydrate, hereafter referred to as fertilizer, was used to impregnate some grass commonly used for roofing houses. It was found that this treatment significantly changed the thermal characteristics of the material. Reasons are adduced to explain these observations.

The effect of potassium aluminium sulphate, (hereafter referred to as alum) on the energy of pyrolysis/combustion of wood cellulose was investigated using thermogavimetric analysis (TGA). It was observed that the energy of pyrolysis of all the materials employed increases with flame retardant loadin
The behaviour of wood with the heat-compressed treatment method was evaluated. Fire retardance and endurance of wood treated with basic nitrogen compounds and phosphoric acid were much improved by the compressed method using a hot press. In this way, the concentration of chemical contents and the de
