The invention discloses an attapulgite volcaniclastic rock high
alumina refractory aggregate sand. The technical scheme is characterized in that the attapulgite volcaniclastic rock high
alumina refractory aggregate sand is composed of highly viscous attapulgite clay powders, attapulgite clay
tailings, volcaniclastic rock mixtures, high
alumina earth, kaoline,
coal gangues and
bentonite tailings. Materials are subjected to uniformly stirring, smashing, soaking, extruding,
calcination, smashing and screening, and then the materials are packaged to form a finished product of the attapulgite volcaniclastic rock high alumina
refractory aggregate sand. The attapulgite volcaniclastic rock high alumina refractory aggregate sand has the advantages that the particle strength is high, the
creep deformation at the high temperature is small, the
corrosion resistance is high, the
thermal shock stability is good, and the like. According to the attapulgite volcaniclastic rock high alumina refractory aggregate sand, a large number of various wastes are utilized in the materials of the attapulgite volcaniclastic rock high alumina refractory aggregate sand, the
resource utilization rate is increased, waste materials are changed into valuable things, the occupied land is reduced, the environment is protected and purified, the energy is saved, the production cost is lowered, the
economic benefits are improved, and the attapulgite volcaniclastic rock high alumina refractory aggregate sand is suitable for refractory concrete constructions.
