A composite material suitable for use in making containers or structures exposed to corrosive chemical attack is achieved by mixing a synthetic plastics resin material with two different hardeners and employing a filler of particulate siliceous material which may be sand, gravel, quartz stones or the like. Structures made from the material are both structurally self supporting and resistant throughout the body thickness to corrosive chemical attack. A skim coat of the same resin with a filler of fine particles, less than 0.5 mm, can be employed, in which case the body can incorporate larger particles, such as 6 mm and above. The synthetic resins employed may be selected from the group comprising vinyl ester, polyester, bisphenol, epoxy and isophthalic resins. |
