A composite material for blast, impact and fire resistant barriers is formed by curing a mixture of a phenolic resin, a neutral, noncorrosive curing agent therefor, fine powders including a hydraulic material, water, fibres, and aggregate. The cured mixture is provided with a continuous reinforcement which may comprise a core of the cured mixture or a protective outer layer. In the preferred arrangement, the composite material is formed into panels for the construction of blast walls. |
