<p>A method of making a finished product includes the steps of (a) providing a dry feedstock selected from the group consisting of particles or fibres of a lignocellulosic material; particles of an expanded mineral; particles of a foamed set hydraulic binder; particles of an undensified silica fume or a mixture of two or more thereof; (b) mixing the feedstock with: (i) a suitable amount of a thermosetting resin in finely divided dry powder form; (ii) a suitable amount of a first binding agent selected from the group consisting of an alkaline earth metal oxide or hydroxide; or a mixture of two or more thereof, in finely divided dry powder form; and (iii) a second binding agent such as a pozzolan in finely divided dry powder form; to give a starting material; (c) subjecting the starting material of step (b) to suitable conditions of temperature and pressure to cause the thermosetting resin to set to form a cohesive product; (d) providing to the cohesive product of step (c) water in an amount sufficient to permit the reaction of the first and second binding agents to form a binder; and (e) allowing the binder to set to form the finished product. The finished product may, for example, be a board.</p> |
