Abstract

The invention belongs to the technical field of treatment and resource utilization of environment-friendly building, building material and solid waste, particularly relates to application of ceramic waste in preparation of high-strength light aggregate, and further discloses high-strength light aggregate prepared from ceramic waste and fly ash, and a preparation method thereof. According to the light aggregate disclosed by the invention, fly ash and solid waste such as ceramic wastes generated in each stage of a ceramic production process are used as raw materials, and the high-strength lightaggregate is prepared from different additives based on the interaction of the characteristics of the ceramic wastes generated in different stages, and has good performance advantages, so that the production cost of the light aggregate is reduced, and the solid waste utilization is maximized so as to obtain building ceramsite with the advantages of light weight, high strength, low heat conductioncoefficient, high refractoriness, good chemical stability, good durability and good thermal insulation and sound insulation performances.

Description

technical field [0001] The invention belongs to the technical field of environmental protection buildings, building materials and solid waste treatment and resource utilization, in particular relates to the use of ceramic waste for the preparation of high-strength light aggregate, and further discloses a high-strength aggregate prepared by using ceramic waste and fly ash. Light aggregate, and further discloses its preparation method. Background technique [0002] Aggregate, also known as aggregate, is a granular loose material used to prepare concrete or mortar. Most of the ordinary aggregates are natural aggregates, and some are industrial waste aggregates (such as metallurgical slag, etc.). As the current building materials gradually develop in the direction of energy saving, environmental protection, light weight, and heat insulation, light aggregates gradually replace ordinary aggregates and become the preferred aggregate material for the construction industry. Light ag...
