<p>For manufacturing a composite material, organic fibrous material like paper, straw, hay, grasses, moss, leaves, reed is mixed with alkali silicate and a fluosilicate as well as with a metllic oxide or a basic metallic silicate forming a higher melting silicate and submitted to a treatment under pressure and temperature. This produces a composite material having high mechanical strength and fire-proof quality.</p> |
