Fireproof material and fireproof plate, and fireproof wall structure for tunnel and construction method
Disclosed are a fireproof material, a fireproof plate, a fireproof wall structure for tunnels and a construction method. The fireproof material includes the following components in weight ratio: 20-35 parts of aluminosilicate; 10-25 parts of calcium carbonate; 5-15 parts of magnesium oxide; 5-15 parts of silica; 20-40 parts of a binder; and 5-10 parts of a curing agent, the binder includes at least one of lithium silicate, potassium silicate and sodium silicate in combination with at least one of quartz sand and industrial sugar; and the curing agent is at least one of lithium oxide and magnesium oxide. In the preparation, firstly forming the mixture of aluminosilicate, magnesium oxide and silica into particles at 900° C.-1250° C., and then mixing the particles with calcium carbonate, the binder and the curing agent, and then pouring same into a forming mold and heating and pressing to form the fireproof material.
