A porous construction material is made by mixing a cementitious material, rubber bits and water. The construction material comprises cured cementitious material and rubber bits in which the rubber bits are bonded together in a porous matrix by the cementitious material. The rubber may be obtained from scrap tyres. The material is cast in place and cured <U>in</U> <U>situ</U>, or cast in block-forming moulds and cured prior to use in e.g. the formation of embankments, walls, roads or bridge decks. Other uses are as fill or back fill for earth works and in land reclamation. |
