CBP 128 ABSTRACT GEL FORMING COMPOSITIONS A substantially dry powder composition which when mixed with water forms a gel comprises a swelling clay, a sodium silicate having a silica to soda weight ratio of about 2.65:1 or below and an inorganic gelling agent for the sodium silicate which gelling agent does not introduce ions which signifi- cantly lower the gelling capacity of the clay. The composition is particularly suitable for use in coal mines as an anti-combustion material.
