  • Porous material and cementitious compositions prepared therefrom
    Patent number: 6248166
    Abstract: A method of treating a shell sand by heating it to 300° C. maximum for a time sufficient to remove substantially all of the water and organic content while maintaining substantially all of the inherent porosity of the shell sand. Generally, the time required varies between 10 minutes maximum at 300° C. to about 1 hour at 95° C. The resulting material is useful in cementitious compositions, particularly mortars, these being characterised by a high flexibility and an exceptionally high degree of resistance to fire or heat.
