Abstract

The invention discloses a calcium silicate board produced from industrial waste slag, which is prepared from the following raw materials in percentage: 35-45% of quartz ore waste slag, 15-25% of cement, 10-20% of carbide slag, 10-20% of reinforced fiber, 5-15% of fly ash and 1% of perlite. According to the calcium silicate board provided by the invention, the wastes are changed into valuable substances through secondary utilization of materials such as the quartz ore waste slag, the fly ash, the carbide slag and the like, thus lowering the production cost, and relieving environmental pollution. The calcium silicate board provided by the invention has favorable performance; the strength is greater than 12 MPa, and the density is greater than 1.20 g / cm<3>; the calcium silicate board has Level A noninflammability and favorable moisture protection and sound insulation effects; and the calcium silicate board has high processability, and can be subjected to cutting, drilling and other operations.

Description

technical field [0001] The invention relates to a building material, in particular to a calcium silicate board produced by utilizing industrial waste slag. The present invention also relates to the production process of the calcium silicate board. Background technique [0002] Calcium silicate board is a commonly used building material. It is mainly made of high-quality and high-grade cement as the base material, combined with natural reinforcing fibers, and then processed by special techniques such as molding, pressurization, and high-temperature steam curing.
